Abstract

The invention relates to a method of measuring the mass center height of an automobile, and belongs to the technical field of automobile measurement. According to the variation relationship between the position of a mass center and loading of a front shaft and a rear shaft in the braking process of the automobile and the principle of moment equilibrium, moment of finishing points of front wheels and the ground of the automobile before and after braking is taken, a moment equilibrium model is built, shaft loading data before and after braking and acceleration in the process of braking are collected, and the accurate mass center height of the automobile is obtained through calculation. Different from an existing static automobile mass center height measurement method, the method of measuring the mass center height of the automobile does not need lifting and hanging mechanisms and an additional measurement device, and is capable of accurately measuring not only a double-shaft automobile, but also a large-size bus, a truck and a multi-shaft automobile.

Description

technical field [0001] The invention relates to a method for measuring the height of a center of mass of a vehicle, belonging to the technical field of vehicle measurement. Background technique [0002] The position of the center of mass of the vehicle is an important performance indicator that affects the safety and handling of the vehicle, and has always been one of the important measurement parameters in the process of vehicle product development and experimentation. The commonly used methods for measuring the position of the center of mass of the vehicle include weight response method and platform reaction support Method, suspension method and zero position method, these methods are static measurement methods, need lifting, suspension mechanism. The weight response method is a measurement method that lifts the front wheels of the vehicle to a certain height. After lifting, most of the body weight is borne by the rear axle under test. For a loaded vehicle, its own weight ...
