Were starting. A high note so were here at the fps Group Checking out an engine block that is almost complete and im here with mehdi puzi the Vice President of fps group and hes going to tell me about why this uh engine block this v16 beast of an engine block is so exclusive to uh countries that you can actually count with the fingers in one hand and whats so special about making of this that not very many countries are able to make it so right please thank you so much for the time uh actually we are the First Company that do the maintenance of the locomotives in iranian railway, since 10 years ago we start the major overhall of the engines in our factory in pare and industrial zone, right . Uh, after some years we face to a problem that we have a problem with engine blocks, this is the main parts of the engines that we have, right . So we are going to sort to how to manufacture these engine block in our country. Uh before that they are importing these engine blocks from foreign country and because of the sheer size and weight this is five ton beast uh its going of to be pretty expensive to import really unmanable yeah its unbelievable thats its because its uh something that um under embargo and its very hard to find the uh countries yeah right manufacturer to import it forget about this uh we are doing the. Um drying, make drying, this is specially kind of engine blocks in all over the world, because what makes this special . All the engine blocks in the normal or general types of engines are casting, but this is fabricated engine blocks, mean we have the separate parts of the engines and we do the assemble of these, so you dont cast these different parts, no, there is no casting parts. In all the uh engine block engine block yeah these are uh forged and these parts separately forged and then assembled together so how does forging work and how is it different from casting and what kind of properties does it have that casting parts dont forging is um different from casting casting you have mold and you uh put the melt uh melted metal into the mold and after. The process you have the final uh parts, but in in uh forging you have to do the you dont have the melt, metal, its goes the temperature to higher, it almost melt, yeah, its not quite melt, and after that you put the pressure, its under the um press device, so its like you have mold, but instead of pouring metal in it, you put the pressure from both sides or like from. Direction into this and then you pressed it into the mold, because of that the characters of the final parts its different, how is it different and why is it better to use forging instead of casting . Most of the time the hardness is very important for us, the toughness is very important to us and whats the difference between hardness and toughness . Hardness is something that it shows the uh being put pressure or impact it doesnt sness you you have. The bending, its how brittle it is, and how much pressure you can on the different s until it break, so this is tougher and harder, harder, yeah, in. Forged parts we have the hardness and toughness increased increased yes okay after we do the assembling all the parts of the engine block after that we should go to the other parts mean we put the crank shaft right the liners power packs head cylinder and all together i think thats the those are the power packs yeah these are the power packs this is the v type engines its not the line one the v type engines eight cylinders on one side the other on the other yeah we have both sides its uh we have power whats the advantage of v type engines compared to the uh the space its much smaller than the other lines one and the power of these engines are increased and we have 16 cylinder in this space if you have one to nine ones the leng should be five meters or so maybe more than five meters now its four okay so when can we expect to actually see this being uh finished and then installed on to an actual train, this is the final parts, we do the test of these uh engine blocks, hope in three months we have the final uh engine blocks and then assemble the other parts, because we do the maintenance of the major overhall of the engines before for imported engines, for imported engine blocks, no the engine the engines are working over the locomotives and when the time is ready we have to to the major over, we have the test device for doing the test and we can measure, we can measure some parameters for the what we do in the measure, right . Because of that, hope in three months we have the complete engine. Okay, heres hoping well be able to see the first train with domestically made engine block and engine as a whole uh sooner rather than later, thank you. Very much for the information, moving right along, not all cables are built the same and so were here at yahoot Cable Manufacturing Company where theyve where they make uh cables that are meant for heavy industries and in particular rail and Transportation Industry when it comes to uh subway trains that are powered by electricity uh, so different cables obviously have Different Levels of resistance to heat, when you think of cables, you probably think the charging cable of your phone or your laptop or other home appliances. The thing with those cables is that they they are based off of thermal plastic substances and uh those thermoplastic substances are based on oil, so they have little to no resistance to heat, and when currents uh eb and flow into these cables uh. Heat is generated and the live and neutral wires within the cable uh can actually melt, the shielding can melt and theyre all based on oil, so they can melt and the cable itself can melt, and uh the the arking that will happen because of the live and neutral uh wires coming into contact with each other, can actually create a sport and actually uh you know put the whole thing up in flames, is very unsafe kind of cabling that can run through lot of. Apartments and houses, so the solution is to switch to Something Like this, or other cables that are based on silicium, the the mineral silicium, so these are not thermoplastic based substances, they are thermosets which have much higher resistance to heat, lets take a look at the the substance itself in the paste form, so this is what a silicium paste or silicon looks like, and out of these we get these heavy duty cables which are actually used in railway and transportation so this red bit is made of silicium and theres another layer of insulation that is made up of fiberglass uh so the silicium layer has a resistance of up to 200 degrees celsius and the fiberglas insulation adds another 600 degrees of resistance up to 800 degrees so uh stuff like this that you actually see here Something Like it this flame has actually been running for the past two or three days since the beginning of this exhibition and you can see that uh this uh thermals thermoset material once it is uh coming into contact with heat and flame it actually turns into ceramic and creates another better layer of insulation than silicium itself so it becomes a more insulating material and you can actually see here that the temperature is at around 800 degrees so there are different tests. That need to be run uh to get the certificates for these cables uh to be able to use them in railway and the power trains uh within the subway system so this is a pretty good demonstration. Of how resilient these cables are, and this lamp has been on for this entire time, uh, the circuits, the the flow of electricity has not been cut for this whole time. Lets talk about another subject that is outside of a train but still within the confines of uh railway and transportation uh we have the laser profile meter and to explain more about it i have ali salehpur the ceo of to tell me about how it works and how it applies to the Railway Industry . Hello, this device is use laser for measurement the z area and move in x and y and then we have a point clot and in here we can show the point clot, so it shows us map of whatever 3d object that is underneath it, yeah yeah yeah we can scan everywhere, for example we can scan centimeter to centimeter, for example this one is 10 millimeter. Into 4 mm whats the smallest diameter that we can actually scan in the in z one micrometer in x and y 30 m so how do we analyze this data and where do we use it uh and after we take a point cloud we use the software for show the topography and then uh we can put for example we can put the line like this and see the profile and see the uh so how much the so this is the profile, so this is the scan itself, the the black line, and we can measure how much this line diverges from the wave that is the average of this uh this this profile and that will give us the roughness number, so the the smaller this range is we can understand that the smoother this surface is correct, this this green line, yes and independ on the product we wants to scan, some product is less. Than micrometer and some products is more and we choose the laser and choose the device for how to scan how to small scan of the area so this green line is the difference between the the red which is the average and the name is right so and uh the roughness so how do we use it in the Railway Industry whats the application in the railway for example we wants to scan the rail and understand whats the damage on the rail we can put this device for example on the train and train moving on the rail and scan the rail and after the scan we can understand which are deformity everythings and another using and we can using on the wheel when we will using on the train they have deformation and we can scan the wheel and understand what the roughness and whats the damage on it uh thats going to be it for this particular product uh to some closing thoughts. In the 10th railway and transportation expo, i got to see firsthand just how thorough and diverse this industry is in iran. I saw Companies Making everything from train cars, wheels, engine blocks and power inverters and lot of things in between with very few missing links, so heres hoping in the 11th, 12th for 13th version of this expo, i see less missing links and less of a way between us and making a uh a. Train from start to finish all by ourselves, heres hoping that happens sooner rather than later. Hope youve all enjoyed it and uh, i will see you in the next week. این بیمار کاندی جراحی با سیستم نویگیشن هستش. یک شکل سه بعددی ما از این تصاویر بیمار که قبلاً گرفته شده ازش تشکیل میدیم و باید مطابقتی از این شکل و شکل سه بعدی و صورت بیمار داشته باشیم. این دستگاه یه دستگاه خیلی پیچیدهه ای راه اندازی نگهداریش تعمیر نگهداریم کار سختیه دوستان طراحی کردن. ما با هم مرحل ابتدااییشو انجام دادیم بعد آوردیم در بالین و الان چندین سالیم استفاده میکنیم ما الان هیچ احساس نیازی نمیکنیم خارجی بریم this system, one is american and the other one is german.
