摘要: 在分析稳定土拌和机全轮转向试验平台工作原理的基础上,对四轮转向各个工况进行试验,绘制出系统的伯 德图,确定了系统的传递函数; 利用MATLAB/SIMULINK 软件对转向系统进行动态仿真。结果表明: 系统具有的幅 值裕度为13.4 dB,相位裕度为48.9°,显示该稳定土拌和机转向试验系统具有一定的储备; 试验系统的响应速度较 快,系统的稳定性符合要求; 四轮转向比传统的二轮转向转弯半径减小约20%左右。

Abstract: Based on the analysis of the all-wheel steering test platform for stabilized soil mixer,a series of tests for each steering working condition are carried out. The transfer function of the system is determined,and Bode diagram is also drawn out. Meanwhile,the system is simulated dynamically by use of MATLAB/SIMULINK software. The research results show that the amplitude margins and phase margins of the steering system are respectively 13.4dB and 48.9°,which meets the stability reserve requirements of the steering system for stabilized soil mixer; the fast response speed and the stability of experimental system also meet the requirement; what's more,all-wheel steering decreases about 20% turning radius than 2 wheel steering does.

Key words: all-wheel steering, experimental research, simulation analysis
