Abstract

The invention discloses a heavy truck cab mass and mass center real vehicle measuring and calculating method, a heavy truck and a medium, and belongs to the technical field of heavy trucks. The heavy truck cab is installed on a suspension system, and the suspension system comprises a suspension spiral spring shock absorber, a turnover hydraulic cylinder assembly, a suspension stabilizer bar and a suspension swing arm assembly; the method comprises the following steps: obtaining sprung bearing masses of left, right, front and back suspended spiral spring shock absorbers of the heavy truck cab to determine the total mass of the heavy truck cab; determining front-back coordinates and left-right coordinates of the mass center of the heavy truck cab according to the sprung bearing mass and the distance between the suspended spiral spring shock absorbers; when the torque of the overturning hydraulic cylinder assembly is zero, the overturning angle of the heavy truck cab passing through the gravity center is obtained; and determining the height coordinate of the mass center of the heavy truck cab according to the forward and backward coordinates and the overturning angle. And the mass center of the heavy truck cab can be measured and calculated with low cost, short period and high efficiency.

Description

technical field [0001] The invention relates to the technical field of heavy truck vehicles, in particular to a method for measuring the mass center of a heavy truck cab and a real vehicle, a heavy truck vehicle and a medium. Background technique [0002] The cab mass and center of mass of heavy trucks are used as design input parameters, which engineers need to use in the subsequent R&D process. Due to the difference in configuration, the quality and center of mass of the heavy truck cab of the same model will be quite different. At present, the measurement of the mass and center of mass of the heavy truck cab requires transporting a separate cab assembly to a professional site for measurement. The main methods include the suspension method, the rotation method or the use of the height of the center of gravity and the moment of inertia. It is also necessary to make special tooling fixtures. The current heavy truck cab quality and centroid measurement methods cannot be car...
