摘　　要：斗杆是电铲工作装置的重要组成部分,降低斗杆的质量对提高电铲的运行性能具有重要意义。为了减轻斗杆的质量,提出Ansys Workbench响应面分析法对电铲斗杆优化设计。为了达到电铲斗杆轻量化,运用UG对电铲斗杆进行建模,以斗杆最小的质量为设计目标,对斗杆进行静力学分析并采用多目标优化方法得到电铲斗杆有限元模型的最优设计方案。在保证斗杆应力和形变的条件下,最终优化后的斗杆质量减轻了4.13%。同时,对尺寸优化前后的斗杆模型静力学结果进行了比较,结果满足电铲斗杆的设计要求。Stick is an important part of the working device of Mechanical Excavator.Reducing the mass of stick is of great significance to improving the running performance of the excavator.In order to reduce the mass of stick,this paper proposes an optimal design of the electric shovel stick based on the response surface analysis method of Ansys Workbench.UG is used to parametrically model the stick.The static analysis of the stick is carried out and the optimal design scheme of the finite element model of the shovel stick is obtained by using the multi-objective optimization method.The mass of the optimized stick is reduced by 4.13%.In addition,the static properties of optimized stick is compared with previous one.The result shows that the requirement of design is satisfied.
