运用Workbench对热室精密压铸机十字架部件优化设计
|
摘要
十字架是压铸机合模机构中极为重要的部分,其所占质量也较大,因此提高十字架设计的合理性,在满足各工况要求的情况下降低它的质量,从而降低其生产成本具有重要意义.近年来人们对十字架鲜有研究.采用ANSYS Workbench分析方法,得到十字架在最大受力时的受力云图,并在Workbench中采用专业的优化分析模块Design Exploration对十字架进行了结构优化.结果表明:经Workbench优化后的十字架的参数尺寸比优化前有所减小,且在满足应力条件下,使其外观更小巧,制造成本更低.
The cross mechanism plays a major role in die-casting machine clamping mechanism,and the quality of the cross mechanism is bigger also. It is important to improve the rationality of the design of the cross mechanism and to reduce both the quality of the cross mechanism and its production cost while meeting the requirements of various conditions. In recent years,there have been few studies on the cross mechanism,and herein,the ANSYS Workbench analysis method was used to get the stress nephogram of the cross mechanism in the maximum stress state. Besides,the professional optimization analysis module " Design Exploration" in the Workbench was adopted to optimize the structure of the cross mechanism. The results show that under the satisfied stress condition,the parameters of the cross were made smaller in size than before the optimization by using the Workbench,making its appearance smaller and the manufacturing cost lower.
