Chain drives being efficient means of power transmission are preferred for this product. The limitation, of course, being catastrophic failure at virtually no prior notice. At high speed, accidents are very likely in case of failure in the chain link. The problem needs to be looked into and investigated for identifying causes for failure. Similarly, upcoming variants to be incorporated with the new solution to eliminate such challenges in the future. The design for the chain would be subjected to F.E Analysis as an Analytical Methodology to find the effect of loads (tension) on the link. The link being a `unit’ of the existing chain would be assessed for performance while tensile loads are exerted at both its ends. Safe loads would be determined and the design tested for safe use in the Automobile. The problem for this work being evaluation of the design using Analytical methodology followed by experimentation to validate it. An existing chain link would be used for benchmarking the research work. Finite Element Analysis tools like HyperMesh and ANSYS are suitable to find the performance of the link under tensile loads. Recommendation over the best suited geometry or material would be presented to conclude the work. KEYWORD: Analytical Methodology, ANSYS, Chain, Chain link, tensile loads. I. INTRODUCTION Chain drives offer non-slip, light weight, inexpensive, compact power transmission compared to belt or gears, but usually at the cost of increased noise and vibration. A brief history of chain drives and the important milestones in their practical development through the late twentieth century can be found in Conwell All chains ‘stretch’ during their lifetime and eventually need replacing. Chains don’t stretch in the same way elastic bands do – they get longer because the metal in the links gradually wear away and makes the overall length of the chain increase. As the chain stretches, the amount of free play increases and you eventually have to move your rear wheel back a bit to take up the slack. If there’s too much slack, the chain will jump around lots whenever you change speed. If there is too little slack, the chain will get over tensioned when you slow down and the back end of the bike becomes un weighted. When you replace the chain, always replace the sprockets too – they’re much cheaper than the chain anyway. It’s a false economy not to, since putting a new chain over worn sprockets will make your chain wear out faster. It’s much easier to loosen the bolt which holds the front sprocket when the chain is still on the bike. You put the bike into a high gear and get someone to stand on the rear brake while you loosen the holding bolt a bit. Since the front sprocket is still attached by the chain to the rear sprocket, it can’t spin around while you try to loosen it. Roller chain, which is the ultimate in chain design, and constitutes the majority of chain produced today, is a relatively new invention. Now they have achieved the highest levels in the world for both quality and quantity. This holds true for conveyor chain, as well. The industries that are the main
