volume reduction 68,65%-75% GE · 模型 274395
We are a team of people of KMWE and TU Delft trying to optimize the volume for the GE engine bracket. At TU Delft a Topology optimisation was done for a 4 bolt solution ( first run 150 iterations on 4x28 cores reduced to 50 iterations) resulting in a volume reduction of 68,65% When further trails to reduce of volume were done after 260 hours computing time; 4:20h wall time on 4x27 cores (400 iterations) we came to the conclusion only 3 bolts are necessary for the load cases resulting in a 75% volume reduction. And still meeting all the demands for the contest if 3 bolt connection is allowed. When even further optimising the topology we could even loose 2 bolts. But surprisingly resulting in only a 74,64% volume reduction. Which is less than the 3 bolt solution. Since the optimised topology models are in stl we have started to first create a volume model with stp extension so we meet the competition recuirements. This takes a lot of time! When we are sure we are also allowed to use less fixing connections we will work on the other models
