基于 A NSYS 的高性能高压水压试验机机架疲劳分析

摘要

Fatigue damage is the most common phenomenon in the form of destruction of machinery and equipment .High performance and pressure hydraulic testing machine frame frequently carries thousands of tons of load in the practical work .In order to guarantee its service life ,in this paper ,the finite element analysis software ANSYS Workbench is used for fatigue analysis .First of all ,it's exerted the meshing and boundary and then the frame strength is analyzed .Finally on the basis of strength analysis ,the fatigue analysis makes sure the frame design reliability of the high performance and high pressure hydraulic testing machine .It ensures its actual service life and reduces the accidents and economic losses caused by fatigue damage .%疲劳破坏在机械装备领域诸多破坏形式中最为常见.高性能高压水压试验机机架在实际工作中频繁地承受几千吨载荷 ,为保证其使用寿命 ,利用有限元分析软件ANSYS Workbench对其进行疲劳分析.首先对其进行了网格划分和边界的施加 ,然后对机架进行强度分析 ,最后在强度分析的基础上 ,进行了疲劳分析 ,验证了高性能高压水压试验机机架设计的可靠性 ,保证了其实际使用寿命.
