摘要
为实现水泥装车自动化,设计了一款新型的水泥装车机,研究了其中关键结构落包板在承受水泥包撞击时的应力变化情况,利用ANSYS进行有限元仿真分析,并对落包板进行结构优化。为分析落包板的尺寸、应力、质量之间的关系,建立响应面模型,并利用多目标优化算法对模型进行优化。优化后落包板的两个局部最大应力分别减小了22.6%、46.5%,同时质量减轻16.5%,可提高装置的经济性与安全性。
In order to realize the automation of cement loading,a new type of cement loading machine is designed.Stress in the key structure falling plate when being hit by the cement package is studied,and the finite element simulation analysis is performed by ANSYS.The structural optimization of the falling package plate is carried out.For analyzing the relation between size,stress and mass of the falling plate,a response surface model is established and optimized using multi-objective optimization algorithm.Simulation and optimization results show that the maximum local stress of two falling plates are reduced by 22.6%and 46.5%,respectively;and the mass of the device can be reduced by 16.5%,implying the improvement in economy and safety of the device.
