摘要
根据某鼓式制动器制动蹄的实体模型,运用CATIA软件建立制动蹄三维模型。将三维几何体导入有限元分析软件ANSYS Workbench,对此模型进行分析计算,得出制动蹄的各阶频率及其振型,并对计算结果进行模态分析。在模态分析和模态振型的基础上,提出对制动蹄进行拓扑优化的方法。通过给定约束条件,优化获得最佳结构拓扑外形,通过对该拓扑外形进行CAD再设计,即可获得满足工程要求的结构。通过分析、优化和设计,可对制动器实现轻量化,带来直接的经济效益。
The three-dimensional model is built for the structure of a solid brake hoof model by using the software CATIA. Then import the geometry into the finite element analysis software ANSYS with new interface of Workbench, and analyze its dynamic behaviors. The inherent frequencies and the vibration modals are obtained, and the modals and the influence factors are analyzed interiorly. Based on this modal analysis, the method of topology optimization is proposed. The structure of optimal topology shape can be obtained through a given constraint condition and we can gain the structure which satisfies the requirement of engineering through redesigning the topology shape with CAD. The brake can achieve lightweight and lead to the better economic benefit through the analysis, optimization and design.
