摘　　要：以某压力机机身为分析对象,运用有限元分析软件、采用FULL法对其进行瞬态计算,并对结果进行分析,获得该类机器在动态力作用下的工作特性。运用有限元分析软件、采用退化原理对机身进行拓扑优化计算,根据动态计算结果和拓扑优化分析结果对结构进行优化设计。仿真结果表明:改进后的结构在保证机身刚度的基础上质量减轻5%且应力分布更均匀。The transient analysis of the frame of a pressure machine was made by Full method through finite element analysis software.The simulation results were analyzed to obtain the work characteristics of the machine under dynamic loading.Adopting degradation theory,the topology optimized design of the frame structure was made in other finite element analysis software.According to the results of dynamic analysis and topology optimization,the frame structure was optimized.After optimizing,the weight of the frame is decreased about 5% and its stress distributing is more even.
