动力总成悬置系统的可靠设计

As the influence of uncertainty factors such as manufacturing error of suspension stiffness on PMSs, a reliable design flow was proposed to perform reliable design of PMS. Variations of reliability were analyzed under different design states. Analysis results of deterministic design was used to show necessity of enhancing reliability of systems. A three-step flow, including performing, choosing and decision was proposed to perform reliable design of a PMS. Finally, this flow was used to perform reliable design of one PMS. Results indicate that a reasonable decision contributes to commonly enhance system reliability. In some cases, a continuously stable region may be found in feasible field at multiple levels of uncertainties, this is an ideal result and it also shows effectiveness of the proposed design flow.
