TRIO 5 Support · 模型 293444
This is my entry for: https://grabcad.com/challenges/redesign-the-structural-support-of-the-metropolis-metro-underframe Due to the complexity of the problem, I focused only on optimizing the beam itself. I left the system of fixing the beams to the main frame unchanged (at this moment I think it is a very good solution and I will not suggest anything else). I focused on reducing the weight of a single support and reducing the number of components it consists of. The solution proposed by me is optimized for robotic welding. For simplifying the assembly, I used one type of 37mm washers (and so I used for simulation). A propose two solutions: with 3 and 5 supports. A single beam weighs 25.275 kg and consists of 7 components (original bracket weighs approximately 56.5 kg and consists of 16 components). In addition, the entire current set weighs 282.5 kg and consists of 5 beams. Where in my proposed solution 3 supports are enough, which gives a total weight of 75.825 kg per set. Which gives more than 400kg of weight savings on the one wagon. However is possible to use 5 of supports (total weight approx 126,5kg per set). If you use 5 supports , I propose also a lighter beam of the same form but from thinner materials (calculations below). Lighter beam weighs 16.68 kg per piece, so all set of 5 weighs 83,4 kg.
