The transmission connecting plate is one of the critical components in an engine, serving to connect the engine and the transmission, bearing part of the weight of both the engine and the transmission, and protecting the clutch and flywheel. Given its harsh working environment, the structural design of the transmission connecting plate directly impacts the overall performance of the vehicle. Additionally, the selection of bolts significantly influences the component’s strength. This paper focuses on a specific transmission connecting plate, introducing the characteristics of its spatial layout, the placement of mounting positions for the suspension system, material selection, and the establishment of a three-dimensional model. Finite element analysis software is employed to conduct modal and strength analyses of the entire system. Based on the load analysis, potential material strength risks are assessed, and the strength of the bolts is evaluated. Through bench testing, the reliability of this design methodology has been validated.
