通过对握索支架的尺寸、形状联合优化,来实现该部件结构最优化。通过Hyper Works软件对握索支架的有限元分析,得到了模型的位移变化和应力分布情况。通过尺寸、形状联合优化设置握索支架数学模型并求解,得到了优化后的模型。为了实现模型的最优化,对优化后模型进行重建并进行有限元分析,来判断刚度和强度是否满足条件。最后在满足刚度和强度条件下,实现握索支架结构最优化。尺寸、形状联合优化方法有利于节省材料、人力、物力、加工费用等,也为林业机械零部件轻量化研究提供有效参考。
By optimizing the size and shape of the grip support, the structural optimization of the component can be realized. Through the finite element analysis of the grip support by Hyper Works software, the displacement and stress distribution of the model are obtained. Through the optimization of size and shape, the mathematic model of grip support was optimized and solved, and the optimized model was obtained. In order to optimize the model, the optimized model is reconstructed and subjected to finite element analysis to determine whether the stiffness and strength meet the conditions. Finally, to meet the stiffness and strength conditions, to achieve the optimal structure of the grip wire holder. The method of joint size and shape optimization can save material, manpower, material resources and processing cost, and also provide effective reference for the light weight research of forestry machinery components.
