Problems solved by technology

At present, most of the research on tracked vehicle steering in domestic academic circles is an extension based on the theory of track-ground adhesion moment. The research on the steering process of the vehicle gives a relatively simple calculation formula under the condition of track slippage, but the article does not take into account the slipping speed in the horizontal and vertical directions, so the conclusion needs to be further studied
In "Analysis of Tracked Vehicle Steering", Cheng Junwei deduced

Embodiment 1

[0059] Such as Figure 1-2 As shown, the invention of this example is a method for testing the steering performance of a tracked vehicle, and the method is realized by a test system; the method includes the following steps:

[0060] (1) Input vehicle operation signal;

[0061] (2) collecting signals by the test system;

[0062] (3) Obtain steering performance parameters.

[0063] The vehicle operation signal in the step (1) is the driver's operation state, including steering wheel angle and accelerator pedal opening.

[0064] The rotation angle of the steering wheel is measured by a cable-type displacement sensor; one end of the cable of the sensor is fixedly installed on the steering wheel through a turntable, and the sensor and the bracket are fixed on the instrument panel bracket. Since the measurement result is a scalar quantity, it is necessary to record the steering state when turning, that is, left steering or right steering.

[0065] The opening of the accelerator ...

Abstract

The invention relates to a method for testing the steering performance of a tracked vehicle. The method comprises the following steps of testing parameters related to the performance of the vehicle in an actual steering test through a testing system, obtaining changes of kinematic parameters and dynamic parameters in the steering process of the tracked vehicle, verifying the reasonability and accuracy of an established steering kinematic and dynamic model of the tracked vehicle, the reasonability of a steering radius correction coefficient formula and the reasonability of a steering angular speed correction coefficient formula, checking the variation range of a steering radius correction coefficient and the variation range of a steering angular speed correction coefficient under general ground conditions, analyzing and verifying the influences of various factors on tractive force and braking force of tracks on the two sides of the tracked vehicle, and examining the variation trend of the kinematic parameters and the variation trend of the dynamic parameters. The various steering parameters generated during steering are obtained at the same time, coupling characteristics between vehicle system dynamics and structural dynamics are accurately reflected, and effective measures are provided for the system structure design, demonstration and improvement on the tracked vehicle.

Description

Technical field: [0001] The invention relates to a method for testing the performance of a tracked vehicle, more particularly to a method for testing the steering performance of a tracked vehicle. Background technique: [0002] Recently, tracked vehicles have played an important role in the military field. After searching the existing technical literature, it was found that Han Baokun, Li Xiaolei, Sun Fengchun and others pointed out in the "Development and Prospect of Tracked Vehicle Dynamics Simulation Technology" published in "Acta Armaments" in May 2003, Volume 24, No. 2, that crawler The purpose of vehicle dynamics modeling and simulation can be divided into: steering analysis, stability analysis, ground pressure distribution and prediction of traction characteristics. According to the different dynamic characteristics of different tracked vehicles, people have established different tracked vehicle models, such as the stationarity model represented by NRMM, the ground p...
