Abstract

The invention discloses a method for calculating static steering torque of a wheel-shoe interchangeable chassis, which relates to the technical field of static steering torque calculation methods for vehicles in a track running mode. It includes the following steps: S1: Initialize parameters, analyze the vehicle load, and obtain the position of each wheel train at the same time; S2: Obtain the bearing capacity of the road wheel axle; S3: Obtain the steering torque generated by each road wheel; S4: Generate the track assembly static steering torque. The present invention can calculate the required steering torque of the wheel-shoe interchangeable chassis without calculating the ground contact pressure distribution, thereby avoiding the complicated process caused by calculating the ground contact pressure distribution, and greatly reducing the complexity of calculating the steering torque.

Description

technical field [0001] The invention relates to the technical field of a static steering torque calculation method of a vehicle in a crawler running mode. Background technique [0002] The wheel-track interchangeable chassis has two driving modes of tires and tracks, so it has the advantages of both tires and tracks, and thus has the advantages of fast driving speed and low ground contact ratio. However, the steering process of the tracked driving mode of the wheel-track interchangeable chassis is different from that of general wheeled vehicles and tracked vehicles, and the steering capability of its steering system needs to be several times that of wheeled vehicles. However, it is one of the most important design parameters for the special steering system of the wheel-track interchangeable chassis to accurately calculate the steering torque required by the wheel-track interchangeable chassis. [0003] At present, the calculation method for the steering torque of the wheel-...
