| 摘 要： | 基于纸浆模塑材料的弹塑性力学特性，利用有限元软件ABAQUS对大型纸浆模塑平托盘在受压情况下的应力场和应变场进行了分析。结果表明，为了准确地预测托盘的力学响应，必须考虑材料的塑性。同时，对给定尺寸的某一纸浆模塑平托盘的最大承受载荷进行了设计。研究结果以期为大型纸浆模塑平托盘的设计和制造提供指导。

| Abstract: | Based on the elastic-plastic properties of moulded pulp material, the strain fields and stress fields of a large-scaled moulded pulp pallet under compressive load are analyzed by using finite element software ABAQUS. Results indicate that the elastoplasticity must be considered for accurately forecasting the mechanical response of large-scaled moulded pulp pallet. Furthermore, the maximal loading capacity of a given sized moulded pulp pallet is determined. The results of the simulations are expected to provide some design parameters for the optimal performance of large-scaled moulded pulp pallet. |
