Abstract

The invention provides a measuring tool and method for vehicle centroid. The measuring tool for the vehicle centroid comprises a horizontal test platform as well as a first scale and a second scale which are arranged on the test platform, wherein a wheel front axle and a wheel rear axle of a vehicle are clamped on the first scale and the second scale respectively; the second scale is fixedly connected to the test platform, the first scale is movably connected to the test platform, and the position of the first scale in the length direction of the test platform and the height of the first scalerelative to the test platform can be adjusted. According to the measuring tool and method for the vehicle centroid, the tool is simple in equipment structure, easy to operate and low in cost, and accurate vehicle centroid coordinates can be obtained.

Description

technical field [0001] The invention relates to the technical field of vehicle measurement, in particular to a vehicle center-of-mass measurement tool and a measurement method. Background technique [0002] The position of the center of mass of the vehicle is an important performance index that affects the safety and handling of the vehicle, and is an important measurement parameter in the process of vehicle product development and experimentation. [0003] The methods for measuring the position of the center of mass of the vehicle in the prior art include a swing method, a suspension method, a platform support reaction force method, and the like. The swing method is to place the vehicle on the test platform, and the vehicle swings freely along with the test platform, and then calculate the center of mass position of the vehicle according to the single-degree-of-freedom weak damping microseismic principle; the suspension method is based on the fact that the object must pass ...
