Optimization on Dynamic Performance of Mining Dumper Frame

HUO Jun-jie;Shenhua Beidian Victory Energy Co. ,Ltd.;  
In order to solve the problems existed small structure strength and large mass of mine dumper frame,the dynamic performance optimization of mine dumper frame structure were realized. Firstly,parametric models of the frame structure were built by using the APLD language of the ANSYS software,the crucial natural frequency,which was the key factor to influence dynamic performance of frame,were determined by modal analysis. Then,considering frame weight as the objective function,the static strength of frame,transient response and crucial natural frequency as the constraint conditions,the sensitivity analysis of all structure parameters were performed to determine the design variables of frame dynamic optimization. Finally,the first order method were used to optimize the dynamic performance of frame by taking the frame crucial natural frequency as the objective function. The results showed that the optimization could improve the static and dynamic performance of frame,and reduce frame weight which improved the economic efficiency of mine dumper transport.
