摘要
在电子设备结构设计过程中,动力学仿真分析技术可以预测产品设计时的薄弱点,优化结构设计方案,提高产品可靠性,避免实验验证后的重大返工,大大缩短产品研制周期、降低生产成本。利用ANSYS Workbench有限元分析软件针对电子设备进行了动力学仿真分析,其中包括模态分析和随机振动分析,并进行了相应的实验,以验证理论分析所提取的仿真模型及所施加边界条件的合理性。结果表明理论分析和实验验证结果吻合得较好。
In the process of structure design of the electronic equipment, the dynamics simulation analysis can predict the weakness of the product design, optimize structure design scheme, improve the reliability of product and avoid major rework after experimental verification, so it can shorten the development cycle and reduce the production cost. According to a certain type of electronic equipment, the ANSYS Workbench was used to carry out dynamic simulation analysis including modal analysis and random vibration analysis, and identifying experiments are carried out to verify the rationality of simulation modal and boundary condition. The result shows that the theory analysis fits well with the experimental verification.
