RELIABILITY-BASED ROBUST OPTIMIZATION DESIGN FOR BANJO FLANGE

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