针对某型号内燃动车进行振动测试,通过分析悬挂部件之间的振动传递、测点之间的相干性及振动频率关系得出静压泵振动和车体局部的弹性振动是导致内燃动车车体地板垂向加速度较大的原因。
According to the vibration test of a certain type of internal combustion motor vehicle, the vibration of static pump and the local elastic vibration of the vehicle body are obtained through the analysis of the vibration transmission between the suspension components, the coherence between the measuring points and the vibration frequency. Vertical acceleration greater reason.
