摘要
介绍了拓扑优化方法的基础理论知识,提出吸能支架的等效模型及理论计算方法。借助Optistruct软件,对保险杠吸能支架进行拓扑优化,设计出合理的吸能支架截面形状,解决了吸能支架在碰撞力作用下向外弯曲偏移的问题。通过低速碰撞试验证明了结构设计的合理性。
The theoretical basis of topology optimization design method is simply presented. The ener- gy absorbing bracket equivalent model and theoretical calculation are put forward. The topology optimization of the energy absorbing bracket is carried out by Optistruct. A reasonable absorption crosssection shape of the energy absorbing bracket is designed. The problem of bracket outward bending offset in the collision force is solved. Then, the rationality of the structural design by low-speed crash tests is proved.
