Abstract: Based on the reliability-based optimization design theory,
the reliability sensitivity technique and the robust design method, the
reliability-based robust design of vehicle components with non-normal
distribution parameters is extensively discussed and a numerical method
for reliability-based robust design is proposed. The reliability
sensitivity is added to the reliability-based optimization design model
and the reliability-based robust design is described as a
multi-objection optimization. On the condition of known first four
moments of basic random variables, the respective program can be used to
obtain the reliability-based robust design information of vehicle
components with non-normal distribution parameters accurately and
quickly. According to the numerical results, the approach pro-posed is a
convenient and practical reliability-based roust design method.
