In order to optimize the structure of the electric car body frame, the static analysis of the car frame were carried on. For the goal of the frame's weight minimum, OptiStruct software was used to topology optimization design. And the optimal material distribution program of the frame ...
A concern in topology optimization is that the design concepts developed are very often not manufacturable. Another problem is that the solution of a topology optimization problem can be mesh dependent, if no appropriate measure is taken.

For the topology optimization, manufacturing constraints of preferred draw direction are applied in order to obtain an optimized material distribution which can be manufactured in the die-cast process. Results from OptiStruct provide a guide for design, but are not optimal for manufacturing due to ...
