Abstract

The invention discloses a compact shelter vibration isolation simulation method for a miniaturized power van. The method comprises the following steps: acquiring a simplified model of a compact shelter vibration isolation system of the miniaturized power van; the vibration isolation system simplified model comprises a shelter frame structure simplified model, a generator set simplified model for connecting a generator and an engine, and a vibration isolation seat simplified model; building finite element models of the shelter vibration isolation system, wherein the finite element models comprise a finite element model of a shelter frame structure, a finite element model of a generator set and a finite element model of a vibration isolation seat; the inherent frequency of the shelter frame structure is calculated, and the inherent frequency of the shelter vibration isolation system is calculated; and comparing the inherent frequency with the working frequency of machines such as a generator and an engine to ensure that the inherent frequency avoids the working frequency of the machines. According to the method, the inherent frequency and harmonic response of the compact power van shelter frame structure and the vibration isolation system are calculated based on the finite element model, the research and development period of a miniaturized power van can be effectively shortened, and the research and development cost is reduced.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a vibration isolation simulation method for a compact shelter of a miniaturized electric vehicle. Background technique [0002] In order to adapt to the traffic capacity of power supply vehicles on narrow roads in urban and rural areas, on the premise of ensuring the power generation power of the power supply vehicles, a split-type miniaturized compact power supply vehicle has been introduced to the market. In order to adapt to the design of miniaturized and compact shelters of power supply vehicles, it is especially necessary to properly modify the conventional diesel generator sets of power supply vehicles. In order to ensure that the retrofit design of the power supply vehicle can meet the noise specification requirements, it is necessary to suppress the vibration of the generator set. The selection of conventional vibration isolation seats needs to wait until the p...
