摘要
以一种新型10MN液压机为例,利用UG和ANSYS软件建立简化的液压机有限元模型,分别对机身结构、上横梁、下横梁进行静力学分析。根据应力以及变形分布规律,验证了10MN液压机在满吨位工况下的合理性。在满足液压机机身强度和刚度的基础上对液压机增加压力,仿真得到该液压机最大允许工作压力为12MN,并对该工况下的上、下横梁的结构进行优化设计,获得最优参数并实现轻量化设计目标。
Taking a new 10MN hydraulic press as an example,a simplified finite element model of the hydraulic press is established using UG and ANSYS software,and the static analysis is carried out on the fuselage structure,upper beam and lower beam respectively.According to the stress and deformation distribution law,the rationality of the 10MN hydraulic press under the full tonnage working condition is verified.When the strength and rigidity of the hydraulic press body are satisfied,if the pressure of the hydraulic press is increased,the maximum allowable working pressure of the hydraulic press is obtained by simulation as 12MN.The structure of the upper beam and the lower beam under this working condition is optimally designed to obtain the optimal parameters and achieve the goal of lightweight design.
