Sažetak
The dynamic performance of a single axle bogie straddle-type monorail vehicle (STMV) includes safe operation and lateral stability. Sensitivity analysis is used to creatively propose a multi-objective fuzzy robust optimisation (MOFRO) method aimed at improving its lateral stability under unpredictable factors. The key suspension parameters were determined through sensitivity analysis based on orthogonal experiments. The fuzzy set method transforms multi-objective functions into single objective optimisation to find the global optimal solution. The results show that the proposed strategy improves the lateral stability of the vehicle under dynamic operating conditions, significantly reducing yaw acceleration RMS, lateral acceleration RMS, and overturning the coefficient by 8.3%, 5.4%, and 26.8%. This method provides a new framework for optimising suspension design and addresses the challenge of lateral stability under dynamic conditions.
