| Abstract (English): |
To achieve the design philosophy of energy conservation, emission reduction, cost decreasing and benefit increasing, taking the engine mount bracket of a medium-sized truck as the research object, this paper adopts a multidisciplinary topology optimization design method, comprehensively considering factors such as structural strength, stiffness and mode to achieve the lightweight design of the mount bracket on the basis of meeting the durability and Noise, Vibration, Harshness (NVH) performance. Lightweight design of the mount bracket structure is performed based on multiple working conditions, and factors such as material strength, modal frequency and stiffness performance are considered comprehensively. While ensuring the rational optimization of the structure, the mount bracket weight is reduced by 20.8%, while the performance is greatly improved, with a modal increase of 13.9% and an average safety factor increase of 35%.
