Driving shaft runout checking method

Abstract

The invention provides a driving shaft runout checking method. An existing template of ADAMS software is modified and optimized to establish a driving shaft runout checking system, so that runout analysis can be performed on a driving shaft more accurately, the feasibility of design checking is realized, and the defects of the existing design checking are overcome. Through setting, measurement andsimulation of configuration parameters, checking analysis of the sliding distance and pendulum angle of the driving shaft can be finished, and the configuration parameters are optimized according toa simulation results to realize an optimal result design. Simulation is simple, accurate and efficient, that is, optimization and analysis of a design result can be finished through parametric design(including parameters such as shaft sleeves and supports), the design feasibility is enhanced, and the complexity and fallibility of secondary checking are lowered. The template can be modified timelyto adapt to the simulation analysis of different models of the same structure suspension; only hard points and related performance parameters need to be changed; and platformization and generalization are realized.

Description

Technical field [0001] The invention relates to the technical field of automobile detection, in particular to a method for checking the beating of a drive shaft. Background technique [0002] When designing a new car, a car manufacturer needs to check the drive shaft runout. At present, manufacturers mainly use the CATIA (Computer Aided Three-dimensional Interactive Application) system for simulation modeling, such as the use of the DMU (Digital Mockup) module in the CATIA system for drive shaft runout verification. [0003] However, using the DMU (Digital Mockup) module in the CATIA system to check the drive shaft runout has the following shortcomings: [0004] 1. In the CATIA DMU module, each component needs to be disassembled and analyzed, and the movement relationship between the components needs to be established. The construction process needs to calculate the relationship between the movement pair, the degree of freedom, and the drive. The process is cumbersome and the result...

AI Technical Summary

Problems solved by technology

[0004] 1. In the CATIA DMU module, it is necessary to disassemble and analyze each component, and establish the kinematic relationship between each component. During the construction process, it is necessary to calculate the relationship between the kinematic pair, the degree of freedom, and the drive. The process is cumbersome and the result is easy. Wrong, the motion model cannot be simulated after the construction is completed, and it is not easy to check the reason;

[0005] 2. In the CATIA DMU module, it is mainly the motion check of pure geometric relationship, which cannot effectively integrate the parameters of shaft sleeves, supports and other parts into the design check, and the design check is not accurate;

[0006] 3. The motion simulation analysis of CATIA DMU is relatively complicated. After the motion analysis results are inappropriate and the hard points are re-adjusted, the measurement and result analysis need to be re-established. The process records cannot be saved effectively, and the process is cumbersome;

[0007] 4. CATIA DMU has limitations for the motion analysis of vehicles with the same platform structure, that is, it cannot realize the generalization of the platform
