Structural Dynamics Simulation Analysis and Optimization of Hexaherdral Tooling

为满足某产品振动试验,合理的设计工装可以体现出产品遭遇真实的振动环境。本文利用ANSYS软件对六面体工装进行了模态分析、正弦振动和随机振动分析,得到了六面体工装和工装加模拟件的振型、应力及加速度响应。最后根据仿真计算结果对六面体工装薄弱环节及缺陷进行优化,保证试验产品能经受振动试验考核。

To meet the vibration test of a product,a reasonable design of tooling can reflect the real vibration environment encountered by the product.In this paper,ANSYS software is used to analyze the modal analysis,sinusoidal vibration and random vibration analysis of the hexahedral tooling,and the mode shape,stress and acceleration response of the hexahedral tooling and the tooling and simulation parts are obtained.Finally,according to the simulation results,the weak links and defects of the hexahedral tooling are optimized to ensure that the test products can withstand the vibration test assessment.
