摘　　要：叉车企业在设计叉车门架时,倾向于使用过量材料来保证叉车门架的强度,这样既增加相关配套设备和负担,也违背轻量化设计原则。以额定载荷为3 t的叉车为研究对象,对叉车门架的主要组成部件进行有限元强度分析,并对举升不同重力的货物时允许司机所产生的叉举操作误差进行计算。应用ADAMS软件对叉车工作过程进行运动仿真分析,计算叉车门架产生的偏转角度和货叉受力等。在仿真分析的基础上,对叉车门架进行拓扑优化,结果表明拓扑优化后外门架的质量减小9%。When forklift company is designing forklift gantry,it tends to use excessive material to ensure the strength of the forklift gantry,which not only increases the relevant supporting equipment and burden,but also violates the principle of lightweight design.Taking a forklift with a rated load of 3 t as the research object,the finite element strength analysis of the main components of the forklift gantry was carried out,and the forklift operation error allowed by the driver when lifting goods with different gravity was calculated.ADAMS software was used to simulate and analyze the working process of forklift,and calculate the deflection angle and fork force generated by the forklift gantry.On the basis of simulation analysis,the topology optimization of the forklift gantry was carried out,and the results show that the mass of the outer gantry is reduced by 9%after topology optimization.
