基于Pro/Mechanica的新型生物质颗粒成型机箱体结构分析及优化

摘要

The structure parameters of biomass (at room temperature) movable plunger-ring die biomass pellet briquetting machine is input into the Pro/Mechanica module. Using CAE technology, a finite element analysis of virtual structure model of the support body of the machine is made to study its stress and deformation. The sensitivity analysis of structure parameters influencing the mechanical properties is carried out and a mathematical model of the support body is established when the support body has the lightest weight. Through optimization calculation, the parameter value to make the structure reach its best mechanical performance is obtained. Based on the optimization result, the original design is improved, which reduces the weight of the support body by 22.98%, thereby saving materials and making the structure safer and more reliable, and at the same time shortening the product development cycle and reducing production and testing cost.%将生物质可移动柱塞式环模颗粒成型机结构参数输入到Pro/Mechanica模块中，通过CAE技术对成型机箱体的虚拟结构模型进行有限元分析，研究其应力和变形情况，并对影响其力学性能的结构参数进行灵敏度分析，建立了箱体质量最轻时的数学模型。通过优化计算，得到使结构达到最佳力学性能时的参数值，并根据优化结果对原始设计进行了改进，使箱体质量减轻了22.98%，既节省材料，又使结构更加安全可靠，同时也缩短了产品开发周期，降低了生产和试验成本。
