基于数值模拟方法的液压支架结构优化

Structural Optimization of Hydraulic Support Based on Numerical Simulation Method

基于CAE优化原理,采用数值模拟方法优化了液压支架的底座结构以及连杆机构尺寸。以底座的外主筋厚度,内主筋厚度以及底板厚度作为设计变量分别进行灵敏度分析,通过基于ANSYS的优化计算,将底座质量降低了5%,应力峰值降低了8%;以连杆机构的尺寸为设计变量,通过基于ADAMS的优化计算,降低了顶梁端点轨迹横向摆动,有效地提升了液压支架的支护效率。

Based on CAE optimization principle, the pedestal structure and linkage size of hydraulic support are optimized by using numerical simulation method. The sensitivity analysis is finished with the pedestal outside main reinforcement thickness, inside main reinforcement thickness and bottom thickness as design variables. Through the optimization calculation based on the ANSYS,the quality of pedestal was reduced by 5%, the peak stress was reduced by 8%. With the size of the connecting rod mechanism as the design variables,through optimization calculation based on the ADAMS,the endpoint trajectory top beam transverse swing is reduced,which can effectively improve the efficiency of hydraulic support.
