基于故障物理模型的可靠性仿真分析方法研究

Research on reliability simulation analysis method based on physics model of failure

以某电源组件为例,提出基于故障物理模型的可靠性仿真分析方法。在产品信息收集、数字样机建模的基础上,通过热测量试验和模态试验完成模型修正与验证,以保证数字样机模型的准确性,提高仿真结果的可信度,为设计改进提供指导。

Taking a power supply module as an example,the reliability simulation analysis method is proposed based on the physics model of failure.Based on the product information collecting and digital prototype modeling,mode correction and verification are completed through the thermal measurement and modal tests to ensure the accuracy of the digital prototype model and improve the credibility of the simulation results,providing guidance to design improvement.
