Due to the configuration of the high-power power pack, the diesel multiple unit（DMU） makes noise control more difficult than that of the electric multiple unit（EMU）.In this paper, through the reasonable design and management of the noise control of a DMU,the noise indicators of the whole vehicle can meet the contract requirements.At the same time, the problem of excessive noise in toilets is analyzed in detail, and an optimized solution is developed.This solution is universal and can be applied to other EMU projects.

分析与总结了EN 15273机车车辆限界中车辆动态限界的计算原理及计算过程,同时详细阐述了满足常用的G1、G2、GA、GB、GC限界要求时,车辆的横向、垂向位移量的计算方法及公式选择,以期为限界计算初学者提供参考,同时为车辆研发设计过程中固化机车车辆限界计算过程打下基础.
