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.
