基于MATLAB/Simulink和ADAMS的拖拉机建模与振动仿真分析
Tractor modeling and its vibration analysis based on MATLAB/Simulink and ADAMS
摘要
Abstract
Based on the theory and method of multi-body dynamics study, the mathematical and mechanical vibration model of JS-754 tractor was established using MATLAB and ADAMS software. The ride comfort of the tractor was simulated with the input signals of random vibration and pulse. The mathematical model consists of 3 degrees of freedom vibration model of tractor using the second equation of Lagrange. From the dynamic characteristics of the tire, a tractor vehicle tire coupling system was established. The mechanical model of JS-754 tractor was established by virtual prototyping technology, and the relationship between the various parts of the vehicle was deifned. Simulation results showed that vertical Root-Mean-Square (RMS) acceleration was acquired which equals 0.390 9 m/s2 on D grade road and the maximum response of the vertical vibrational acceleration velocity was less than 34.59 m/s2 on the seat. The signal of tire characteristics with the tractor driving was obtained, the frequency range of vibration was concentrated between 3 and 5 Hz on the seat by simulation. The research shows that the ride comfort of JS-754 tractor is good. The proposed method of tractor vibration modeling is of great reference value, and it can provide the theoretical basis and modeling ideas for the research on the ride comfort of the tractor and other non-road vehicles.关键词
