摘要
针对2000kN数控精密金属粉末液压成形设备的框架机身进行了结构分析和优化设计,对框架机身的简化模型进行静、动态有限元计算。在静态分析中对其进行强度校核和刚度校核,通过模态分析给出了机身振动的固有频率及相应振型。在此基础上,采取结构改进措施,降低了设备机身的制造成本,保证了设备性能。
Through finite element static and dynamic analysis, structural analysis and optimization of the main frame of hydraulic powder-forming equipment were done. With static analysis, strength check and rigidity check were finished, and with modal analysis, natural frequencies and mode shapes of the main frame were presented. As a result, some structural improvements were used to reduce the cost of manufacturing the main frame and ensure the performance of the equipment.
