某雷达模块的振动夹具设计

随着电子产品环境适应性要求的提高,特别是振动性能要求的不断提高,振动试验在电子产品环境试验中的作用日益显著。振动试验通过模拟产品在运输、安装及使用过程中所遇到的各种振动环境影响,来确定产品是否能承受各种环境振动,从而判断其能否达到实际使用要求。同时,振动夹具在振动试验中起着重要的作用,其设计的好坏决定着振动试验的成功与否。文中首先对振动夹具的设计进行了理论分析,然后通过某雷达模块振动夹具的设计过程,提出了利用软件仿真并进行逐步优化的设计方法,总结了设计振动夹具的心得,为以后的振动夹具设计提供参考。

Design of Vibration Fixture for a Radar Module

With the increase of environmental suitability, especially the vibration performance for electronic products, vibration tests play a more and more important role in environmental trials of electronic products. Through simulations of various environmental vibration impacts during the process of transportation, installation and operation, it is determined whether the product can withstand various environmental vibrations and whether it can meet the actual operation requirements. The vibration fixture plays a significant role in the vibration tests and determines whether the vibration test is successful or not. In this paper the design of the vibration fixture is theoretically analyzed first. Then with the design process of the vibration fixture for a radar module as an example, the design method of software simulation and gradual optimization is put forward. The vibration fixture design experience is summarized at last to provide some reference for future vibration fixture design.
