Abstract

The invention belongs to the technical field of simulation of gearboxes, and provides a method for designing a universal model of a Matlab based dead axle gearbox in order that the universal model can be applied to simulation of an AMT (automated mechanical transmission) system and can complete dynamic analysis during gear shift and control strategic debugging. The method designs a universal gearbox dynamic model which is integrated with a synchronizer and shafting, realizes prediction of performance of a control system, solves the problem that variation laws of torque and rotation speed during gear shift cannot be obtained, provides a powerful support for selecting gear shifting laws during development of the AMT system and power breakage control during gear shift, and gives a big help for improving gear shifting stability and reliability of friction components of vehicles. By the method, development period of the AMT system is shortened, development cost is reduced, work efficiency is improved, and great and progressive significance is provided for project development.

Description

technical field [0001] The invention belongs to the technical field of gearbox simulation, and in particular relates to a design method of a general model of a fixed-axis gearbox based on Matlab. Background technique [0002] At present, most of the AMT system simulation platforms in China are simply built for gearboxes, and cannot perform dynamic analysis of the shifting process, while very few gearbox models built are designed for a single gearbox, which has no versatility and requires Long-term design and debugging cannot quickly provide support for the control system design. [0003] Therefore, it has become an important task to design a general model of fixed-shaft gearbox, speed up the design progress of the simulation platform, and provide support for the design and debugging of the AMT control system as soon as possible. Contents of the invention [0004] (1) Technical problems to be solved [0005] The technical problem to be solved in the present invention is t...
