Abstract:

In order to improve the running performance of variable-gauge trains when working on different gauge lines， a PCA assigned signal-to-noise ratio-based method is used to optimize the suspension parameters. It established the dynamic simulation model of 1 435/1 520 mm high-speed variable-gauge train based on SIMPACK. The key suspension parameters were selected by parameter test method Pareto diagram. Based on the optimal Latin hypercube design method， 200 groups of key suspension parameters were selected for simulation test. The signal-to-noise ratio is used to analyze the dynamic performance. Assigning the weights of various dynamic indicators through principal component analysis， and obtain the optimized values of key suspension parameters for variable-gauge trains under two different gauge combinations. The results of parameter optimization are tested and verified， which show that the dynamic performance of the optimized suspension parameters on the two gauges meets the standard requirements， and the vehicle has better dynamic performance.

Key words: railway transportation, variable-gauge trains, optimize parameter, dynamic index, the optimal Latin hypercube, principal component analysis
