| Abstract: | Based on the stable reliability-based optimization theory,the stable reliability sensitivity technique and the robust design method,the stable reliability-based robust design of compressive bar is extensively discussed and a numerical method for stable reliability-based robust design is proposed.The reliability sensitivity is added to the reliability-based optimization design model and the stable reliability-based robust design is described as a multi-objection optimization.The stable reliability-based robust design approach is formulated.The corresponding program can be used to obtain the reliability robust design information of compressive bar accurately and quickly.According to the numerical results,the approach proposed is a convenient and practical stable reliability-based roust design method. |
