某混凝土搅拌车差动制动防侧翻控制仿真分析

Simulation of Rollover Prevention Control Based on Differential-braking for a Concrete Mixer Truck

针对混凝土搅拌运输车侧翻事故多发的现象,该文介绍了差动制动的防侧翻原理,基于ADAMS/Car建立了搅拌车的整车动力学模型,设计了针对搅拌车的差动制动防侧翻控制系统,并结合ADAMS/Car和Simulink建立了联合仿真试验模型,仿真试验结果表明,通过虚拟试验仿真可以合理的选择侧翻门限值,设计的差动制动防侧翻系统可以有效防止高速转向引起的车辆侧翻。

As the phenomenon of many rollover accidents of the concrete mixer truck,it has introduced the principle of differential braking control strategy,and designed a control system towards concrete mixer truck to avoid rollover accidents.Based on ADAMS/Car and Simulink the analysis has proved that through choosing the reasonable rollover limit value,differential braking control strategy can prevent rollover accident caused by high speed turning,but has nearly no influence on safe running.
