Vehicle Oil Sensor Vibration Isolation Technology Research

Abstract

During the acceleration of the vehicle, the oil sensor will generate violent vibration, which will affect its measurement accuracy. For the vibration problem of the oil sensor, a vibration isolation device is proposed to achieve the purpose of vibration isolation. To this end, this paper takes the oil-liquid sensor vibration isolation device as the research object, establishes a two-dimensional CFD simulation model with the help of Fluent software, and studies the influence of different damping media and spring stiffness on the oil-liquid sensor integration device. The results show that the use of a spring with a stiffness coefficient of 1500N/m in the horizontal direction, a spring with a stiffness coefficient of 3000N/m in the vertical direction and diesel oil or kerosene as the damping medium can effectively improve the vibration isolation effect of the vibration isolation system for the oil-hydraulic sensor, reduce the data acquisition error caused by severe vibration, and provide a theoretical basis for the optimal design of the vibration isolation system for the oil-hydraulic sensor.
