仿真分析在热管理控制阀振动工装设计中的应用

Application of Simulation on TCV Vibration Tooling Design

振动工装是新能源汽车热管理控制阀开展振动相关的试验时必备的配套产品,它的质量好坏将直接影响试验的测试结果。本文针对某汽车热管理控制阀在进行振动耐久试验时热管理控制阀支架在安装孔附近出现破坏的问题,采用有限元分析的方法对振动工装进行了模态分析。结果表明,振动工装的固有频率太低,会导致其传递给支架的振动能量太大,因而造成支架破坏。将振动工装进行优化,支架没有发生破坏现象,试验顺利通过。这为后续新能源汽车热管理控制阀振动试验工装的设计和工程试验提供参考。

Vibration tooling is a necessary product for vibration test of new energy vehicle thermal management control valve(TCV),its quality will affect test results directly.In the process of the vibration durability test,a new energy vehicle TCV bracket is cracked.To solve the problem,the modal analysis of the vibration tooling is carried out by finite element method.The results show that if the natural frequency of the vibration tooling is too low,the vibration energy transferred to the bracket will be too large,resulting in the cracking of the bracket.After the vibration tooling is optimized,there is no crack of the bracket,and the test can be passed smoothly.This provides a reference for the subsequent vibration tooling design and engineering test of new energy vehicles TCV.
