Abstract

The invention discloses a multi-axle vehicle axle load determining method and system and a vehicle. The multi-axle vehicle axle load determining method comprises the steps that according to the givenaxle load and the axle loads of a plurality of axles, the balance constraint of the multiple axles in the vertical direction is obtained; according to the multiple distances between the vehicle mass center and the multiple axles and the axle loads of the multiple axles, the torque balance constraint of the multiple axles is obtained; according to the comprehensive rigidity of suspension frames andtires of the multiple axles, the multiple distances between the vehicle mass center and the multiple axles, the free strokes, generated by the heights of the suspension frames of the multiple axles,of the suspension frames of the multiple axles and the axle loads of the multiple axles, the suspension and tire deformation coordinate constraint of the multiple axles is obtained; and according to the balance constraint of the multiple axles in the vertical direction, the torque balance constraint of the multiple axles, and the suspension and tire deformation coordinate constraint of the multiple axles, the axle loads of the multiple axles are determined. The multi-axle vehicle axle load determining method and system and the vehicle have the following advantages that axle load distribution of the multi-axle vehicle can be accurately determined.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a method for determining the axle load of a multi-axle vehicle, a system for determining the axle load and a vehicle. Background technique [0002] The axle load of a multi-axle vehicle is a necessary parameter for general layout, frame strength check, vehicle dynamics analysis, especially vehicle braking performance and handling stability performance analysis and evaluation in the process of vehicle scheme design. For vehicles with two or more unbalanced suspensions, the calculation of the axle load is a typical statically indeterminate structure, and it is impossible to use a single static balance to analyze and calculate the axle load of the vehicle. Contents of the invention [0003] The present invention aims to solve at least one of the above-mentioned technical problems. [0004] Therefore, the first object of the present invention is to propose a method for determinin...
