摘　　要：应用ABAQUS有限元软件,模拟分析了纸浆模塑托盘支腿在压缩载荷作用下的非线性变形特征和屈曲行为。通过建立简化的托盘支腿模型,设置不同壁厚,对各模型进行了有限元非线性屈曲分析,得到了模型受载变形全过程的力-位移曲线。结果显示,支腿最大承载能力随壁厚增加而增大,支腿承载能力取决于支腿壁厚区间。The non-linear buckling behavior of the outrigger unit of molded pulp pallet under load compression was simulated and analyzed by using finite element software ABAQUS. The simplified models of the outrigger unit were established. Finite element non-linear buckling analysis was carried out on the models with different wall thickness and the force-displacement curves of outrigger units were obtained. The result showed that with increases of wail thickness, the load-bearing capacity of the structural unit increases; the wall thickness range of an outrigger unit mainly determines its load-bearing capacity.
