摘要
在分析大型复杂机械系统的动态特性时,会出现由于其自由度数多而导致分析计算困难的现象,而固定界面模态综合法就是解决这一问题的理想方法。合模机构是压铸机的关键部件,其可靠性和稳定性直接影响压铸机整机的性能和品质。基于固定界面模态综合法,利用ADAMS软件对压铸机合模机构的固有特性进行了分析,评价其现有结构系统的动态特性,为其动力学优化提供依据。
In the analysis of the dynamic characteristics of the large and complex mechanical systems,there will appear the phenomena of calculating with difficulty because of the large number of degrees of freedom.So the fixed-interface modal synthesis method is an ideal way to solve this problem.Clamping mechanism is the key component of the die-casting machine;its reliability and stability have a direct impact on the overall performance and quality of the die-casting machine.Basing on the fixed-interface modal synthesis method,it utilized the ADAMS to analyze the inherent characteristics of the clamping mechanism to evaluate the dynamic characteristics of the existing structural system and provide a basis of its dynamic optimization.
