摘要: 采用全液压转向系统的重载运输车辆在颠簸、急转弯工况下,系统负载会发生突然变化,此时系统会出现压力冲击、液压能异常损失,严重时会导致液压元件损坏和系统崩溃,针对该实际问题,提出一种集成于全液压转向系统的液压能量再生模块,以实现回收并利用冲击能量、减缓转向系统压力冲击的目的。基于AMESim分别对含有能量再生模块的有负载反馈全液压转向系统和无负载反馈全液压转向系统建立数学模型,研究能量再生模块的动态特性,并对含有该模块的试验样车开展了不同路况下的路面试验。仿真和试验结果均表明:能量再生模块能量再生效果好,在重载运输过程中能有效吸收压力冲击,且能量再生模块释放液压能平稳有效。

Abstract: Heavy trucks using full hydraulic power steering system experience load suddenly changed during bumpiness or sharp turns, the system would suffer pressure shocks, losses of hydraulic energy, serious hydraulic component damages and even system collapse. To solve the problems, a power regeneration module was introduced, which was integrated into the full hydraulic power steering system to collect and re-utilize the energy and reduce the pressure impacts. Based on AMESim, mathematical models with power regeneration were established for full hydraulic power steering system with and without load feedbacks. To study the dynamic characteristics of power regeneration, and the module was tested with a heavy truck under different road conditions. Both of the simulation and test results show that the power regeneration module has good effectiveness, may effectively absorb pressure shocks in the processes of heavy load transportation, and may also smoothly release hydraulic pressure. 

Key words: full hydraulic power steering, power regeneration, load feedback, AMESim simulation, dynamic characteristics
