Numerical analysis of local reinforcement of composite case under complicated load

The composite case of SRM was analyzed under the combined load condition, consisting of axis pressure, external pressure and bending moment. The analysis results show that the layer design of the case structure isn't proper, which can lead to structure failure because of the bad distortion coordination. Therefore, the local reinforcement of structure under complicated loads is investigated via numerical simulation, and the optimized scheme is proposed. The result shows that load-bearing capability can be greatly improved. This method is available for improving the structure design.
