Problems solved by technology

However, in the general suspension motion simulation, a simple rigid body kinematics model is often used, ignoring the mechanism displacement caused by the force deformation of flexible components such as rubber bushings in the system, and the motion trajectory of the wheel cannot be accurately simulated. Wheel pack results don't match reality very well
[0005] Therefore, there is currently no method for generating an envelope of wheel motion that can accurately simulate the wheel motion trajectory

Abstract

The invention provides a method for simulating a motion curve of an automobile front steering wheel. The method comprises the steps that a wheel jumping and steering first coupling relation curve of the automobile front steering wheel is obtained; a wheel jumping and steering second coupling relation curve considering elastic piece deformation of the front steering wheel is obtained; a wheel jumping and steering final coupling relation curve of the automobile front steering wheel is obtained by combining the first coupling relation curve and the second coupling relation curve; a motion curve file of the front steering wheel is generated according to the final coupling relation curve. The invention further provides a method for manufacturing an envelope surface of the automobile steering wheel. The obtained motion curve of the front steering wheel can reflect a wheel track more accurately, and the reflection is more close to the actual situation; the obtained envelope surface has high reliability and safety.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method for simulating the motion track of the front steering wheel of the automobile and making an envelope surface. Background technique [0002] The vehicle's wheel motion envelope refers to the movement space occupied by the wheel tires during the process of the wheels bouncing up and down with the suspension and turning to each limit position under various driving conditions of the vehicle. It determines the opening shape of the wheel cover and the fender, and can also be used to check the dynamic clearance and motion interference between the wheel and the surrounding subsystems and components, and may even drive the wheel track, Adjustment of the minimum turning radius of the vehicle, etc. Therefore, in the development stage of the vehicle project, analyzing and designing a more accurate wheel package at an appropriate development node plays an important role and sign...
