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 runout of a drive shaft. Background technique

[0002] Automobile manufacturers need to check drive shaft runout when designing new vehicles. At present, manufacturers mainly use the CATIA (Computer Aided Three-dimensional Interactive Application) system for simulation modeling, such as using the DMU (Digital Mockup) module in the CATIA system to check the runout of the drive shaft.

[0003] However, using the DMU (Digital Mockup) module in the CATIA system to check the runout of the drive shaft has the following shortcomings:

[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 i...
