基于ANSYS的热电池组合结构有限元动态分析

Research of dynamic analysis of thermal battery structure with finite element method based on ANSYS

随着热电池结构技术的发展,热电池组合结构在承受振动、冲击等力学环境中,所表现出的力学动态特性对热电池组合结构的设计具有重要的指导价值。热电池组合结构本身具有一定的刚性和固有频率,这些特性均是热电池组合结构动态设计中的重要参数。为了避免外力频率和固有频率相同而发生共振,采用ANSYS workbench12.0建立了热电池组合结构的有限元模型,并基于该模型,对热电池组合结构进行了静态强度分析以及模拟力学环境中的结构动态特性分析。

With the development of thermal batteries structure technology, the dynamic characteristic presenting under the mechanical environment of vibrates and impact, had an important guideline value for designing the combination structure of thermal battery. The combination structure of thermal battery in itself had a certain degree of rigid and natural frequency, which were the important design parameter for dynamic loading. To avoid the resonance as foreign frequency was close to natural frequency, a finite element model of thermal battery combination structure by ANSYS workbench12.0 was built. Based on the model, the static strength and dynamic characteristic under a simulation mechanical environment were studied.
