Embodiment 1

[0046] Such as figure 1 As shown, a method for calculating the axle load of an articulated three-axle passenger car includes the following steps:

[0047] S1: Obtain the mass of each component of the front carriage, and the horizontal distance from the corresponding centroid position to the support axis of the front carriage;

[0048] S2: According to the mass of each component and the horizontal distance from the corresponding centroid position to the support shaft of the front car, use the preset algorithm to calculate the axle load of each support shaft of the front car;

[0049] S3: Obtain the mass of each component of the rear compartment, and the horizontal distance from the position of the corresponding center of mass to the support shaft of the rear compartment;

[0050] S4: According to the mass of each component and the horizontal distance from the corresponding centroid position to the support shaft of the rear compartment, the axle load of each support shaft of th...

Abstract

A method for calculating the axle load of an articulated three-axle passenger car, comprising the steps of: obtaining the mass and center of mass of each component of the front compartment, and the horizontal distance from the position of the corresponding center of mass to the support shaft of the front compartment; For the horizontal distance of the support shafts of the front carriage, use the preset algorithm to calculate the axle loads of the support shafts of the front carriage; obtain the mass and center of mass of each component of the rear carriage, and the horizontal distance from the position of the corresponding center of mass to the support shaft of the rear carriage; according to each component The weight of the mass and the horizontal distance from the corresponding center of mass to the support shaft of the rear compartment, the axle load of each support shaft of the rear compartment is calculated using a preset algorithm; finally, the total axle load of each support shaft is obtained according to the axle load of each support shaft. Through this method, the axle load distribution can be checked without waiting until the actual prototype vehicle development is completed, reducing design changes in the prototype vehicle development process and shortening the product development cycle; and the scheme can be adjusted in time during the design process to optimize the axle load distribution.

Description

technical field [0001] The invention relates to the technical field of mechanical measurement, in particular to an axle load calculation method of an articulated three-axle passenger car. Background technique [0002] With the development of cities and the increase of population, articulated buses occupy an important position in public transportation because of their maximum transport capacity among buses. The safety of passenger cars is also a concern of people. During the design process of passenger cars, it is necessary to calculate the axle load and calculate the axle load distribution ratio. The ideal axle load distribution can achieve the stability of the car and make the tires wear evenly, while the unreasonable axle load distribution will affect the dynamic performance, braking performance, passability, economy and operation stability of the vehicle. If the axle load distribution ratio is unreasonable according to the axle load calculation, the vehicle layout scheme...
