Suggestions for optimizing the suspension design of a self-propelled modular vehicle
Abstract
The article is devoted to improving the suspension design of a self-propelled modular transporter (SPMT) using optimization methods. Based on the conducted studies of the stress-strain state of the SPMT suspension and mathematical modeling of forces in the elements of the SPMT suspension, the following are proposed: 1) updated coordinates of the hydraulic cylinder rod mounting axis; 2) cutouts in the upper levers and the metal suspension body; 3) localized reinforcements in the lower arm mounting assemblies; 4) rounding in areas of sharp transitions. These design changes will reduce the average and maximum stresses in the SPMT suspension design by 4-10%, as well as reduce the weight of the suspension by 6-8%, without changing the material of the SPMT suspension components.
