摘　　要：针对某型号服务器的振动试验要求,对实验室原有夹具进行了优化设计。在设计过程中充分利用了试验验证与有限元模拟分析相结合的方法,确定了有限元模型应该达到的设计指标。优化设计过程中遵循着先优化结构质量分布,再优化结构刚度分布,最后优化结构关键尺寸的思路对实验室原有夹具进行并完成了优化设计。在夹具加工完成后对夹具进行了验证试验,验证试验结果表明优化后的夹具各项指标均符合设计要求,优化设计取得成功。For the need of a certain server’s vibration test,the new fixture is designed and optimized based on the lab’s original fixture.The experimental verification and finite element analysis by ANSYS software are combined during the fixture’s design and optimization to confirm the index should be meted by finite element model.The way of optimization is following the order of mass optimizing,stiffness optimizing and critical size optimizing.The experimental verification were done after the new fixture have finished,the result of verification meets the demand.
