| Abstract: | Finite element model of a minibus body is created by Hypermesh software based on CAD model. By Optistruct and LMS. virtual-lab software, the body structural modals and acoustic modals in the free state are calcalated. Analyzing its impact on ride comfort, and making relevant recommendations to guid body design expectations in the minibus pre-design phase, which is in a timely manner to compensate for the defects in the design, and enhance its market competitiveness. |
