摘　　要：为探明叉车在偏载状态工作时,门架系统中左右起升液压缸的作用力是否均等,以某叉车中门架为例,运用Hyper Works软件,采用2种不同的边界条件进行有限元分析,分别模拟左右作用力均等和作用力不等2种情况;并对该门架进行应力应变电测试验,再将有限元分析结果与测试结果进行对比,得出结论:左右作用力不等的方案更接近电测试验结果,即叉车门架系统在偏载状态工作中左右起升液压缸作用力不等,为叉车门架系统的分析提供依据.In order to find out if the force of the right and the left hydraulic cylinders is equal when the forklift mast system in partial load condition, this paper does the finite element analysis by Hyperworks to simulate the situations of the right and left force is equal and unequal in two different boundary conditions. Then we conduct the stress and strain test for the forklift mast and compare the results of the finite element analysis and the test. Finally, we get the conclusion that the scheme of unequal force is closer to the result of the electrical experiment, which proves the force of the right and the left hydraulic cylinders is not same in partial load condition, and provides the basis for the analysis of the forklift mast system.
