摘要
以提高柔性定位平台的疲劳寿命、减轻柔性定位平台的质量为目的,对搭建的初始模型进行有限元分析并获得位移和应力云图,得到位移和应力随着载荷变化的趋势,通过疲劳分析获得最低寿命点的寿命。对柔性定位平台进行拓扑优化,根据优化后的结果对柔性定位平台重新建模,将优化前后模型相对比。结果显示:优化后的柔性定位平台提高了寿命,降低了质量。
To improve the fatigue life and alleviate the quality of flexible positioning platform,the finite element analysis of initial model is carried pout to abtain displacement and stress nephogram,the trend of the displacement and stress with the load change,and gain the life of the lowest life point through fatigue analysis.Topology optimization of flexible positioning platform is conducted,and with the optimation result,the flexible positioning platform is remodeled and the comparison is made between pre&post optimization models,which shows that the service life of flexible positioning platform is improved while the quality is reduced.
