【摘要】：差动液压回路广泛应用于制动系统,尤其是在蓄能器的充液控制下保障了制动压力的稳定。在研究差动液压缸数学模型和蓄能器制动动态数学模型的基础上,对制动过程中油缸有杆腔和无杆腔的压力分布情况进行了仿真和实验研究,得到了一致的结果。研究结果表明:蓄能器充气压力的合理选择对液压系统的制动效果影响很大,应选择在系统工作压力的0.7~0.9倍之间;制动过程中压力出现波动情况,制动效果受无杆腔的制约,这为实际生产中制动系统的控制和选型提供依据。
[Abstract]:Differential hydraulic circuit is widely used in braking system, especially in the hydraulic control of accumulator to ensure the stability of braking pressure. On the basis of studying the mathematical model of differential hydraulic cylinder and the dynamic mathematical model of accumulator braking, The simulation and experimental study on the pressure distribution of the rod cavity and the rod less cavity in the cylinder during the braking process are carried out, and the results are consistent. The results show that the reasonable selection of the charging pressure of the accumulator has a great influence on the braking effect of the hydraulic system. The pressure fluctuates in the braking process, and the braking effect is restricted by the rodless cavity, which provides the basis for the control and selection of the braking system in actual production.
