Design of GFRP Engine Mount Frame by Using Topology Optimization

摘要

With the help of topology optimization and coupling analysis, the virtual prototyping technology was first used in designing a GFRP engine mount frame. In this design, the topology optimization technology based on a variable density method was introduced in order to reduce the structural weight while having enough stiffness. Then, a design for manufacturability of GFRP engine mount frame was performed on the basis of the instruction of topology optimization. After that, a coupling analysis combined with the fiber orientation was carried out to verify the performance of the designed frame. The result shows that the designed GFRP engine mount frame not only meets the requirement of strength and frequency, but also reduces about half weight compared with the steel frame, which means a significant lightweight effort.
