摘要
在设计研制了既能保持全动力液压制动系统优点,又能降低整机制造成本的双液动力转换器的基础上,建立了包括转换器在内的全动力液压制动系统动态数学模型。采用仿真与试验相结合的方法,对系统的动态响应特性进行了分析。通过台架试验验证了仿真模型,掌握了主要系统参数对制动压力响应特性的影响规律。应用结果表明,双液动力转换型制动系统能够满足轮式工程车辆的要求。
On the basis of design and manufacture of a dual fluid power converter which can both retain the advantages of full power hydraulic braking system and lower the cost of the whole machine, a mathematic model of responding characteristics in full power hydraulic braking system with the converter was established. By combining the means of simulation and experimentations, the responding characteristics of completed full power hydraulic braking system were analyzed. The simulation model was also verified by experiments and the rules that the system parameters used to affect the responding characteristics of braking pressure were learnt. Through industrial utilization, it can be conducted that the braking systems with the converter can meet the requirements of wheeled construction vehicles.
