Dynamic analysis modular-modeling method for gear transmission system

Abstract

The invention discloses a dynamic analysis modular-modeling method for a gear transmission system. Parts of the gear transmission system are modularly processed to form three modules with specific input and output interfaces, i.e. a shaft module, a gear pair module and a planetary gear module, according to the dynamic rapid evaluation requirements of a gear transmission system configuration design scheme; an overall mass matrix and an overall rigidity matrix of the gear transmission system can be rapidly generated only by using transmission part connecting relationship information, gear basic parameters and shaft structure basic parameters are in the gear transmission system configuration design scheme as input data, so that a dynamic analysis model of the gear transmission system is established, and the dynamic analysis efficiency of the gear transmission system can be greatly improved. In addition, a shaft with a complex structure is discretized into a plurality of shaft sections to form a plurality of shaft units, so that the accuracy of a dynamic calculation result can be improved.

Description

technical field [0001] The invention belongs to the technical field of dynamics and relates to a modular modeling method for dynamic analysis of a gear transmission system. Background technique [0002] Gear transmission system dynamics is a science that studies the dynamic behavior of a gear transmission system in the process of transmitting motion and power. It takes the gear transmission system as the object and takes the dynamic characteristics of the gear pair meshing process as the core to improve and improve the gear transmission system. For the purpose of the dynamic behavior of the system, on the basis of considering the dynamic characteristics of each component of the system, using the theory and method of vibration mechanics, to study the basic laws of vibration, impact and noise in the transmission power and motion of the gear transmission system, for the design and manufacture of small The gear transmission system with vibration, low noise, high reliability and ...

AI Technical Summary

Problems solved by technology

This method has the limitation that it is not universal. If the configuration of the gear transmission system changes, it is necessary to re-analyze the force analysis of each part of the system to establish a dynamic model, which makes it difficult for various gear transmission system structures. The process of evaluating the dynamic characteristics of the type scheme becomes very complicated and inefficient; in addition, abstracting the shaft with a complex structure into a concentrated mass point will affect the accuracy of the dynamic calculation results to a large extent
