利用防抱制动系统（ABS）液压实验台，进行了ABS压力梯度多种工况的实验测试，包括普通制动、长加长减制动和阶梯增压、减压制动等工况研究。实验结果表明：在普通制动、长加长减制动和阶梯制动实验中，主缸压力分别在8、12、15MPa时达到最大极限值，同时阶梯增压和减压在脉冲宽度下的压力梯度随主缸压力增大而呈明显增加趋势。分析了其变化的原因。该研究为ABS轮缸压力的精细调节和精确理论建模提供了重要的卖验依据。

The pressure gradient of the anti-lock braking system （ABS） was experimentally studied using an ABS hydraulic test bench for various conditions including normal brake, on-off brake, and step brake. The pressure gradient was analyzed with the master cylinder pressure and solenoid step pulse width being changed. The results show that for the normal brake, on-off brake, and step brake conditions, the pressure gradient achieves the maximum limit with the master cylinder pressure of 8, 12 and 15 MPa, respectively. The pressure gradient for the pressurization and decompression steps in the pulse width significantly increases with increasing master cylinder pressure. The results provide an important experimental reference for fine-tuning and precise theoretical modelling of ABS wheel cylinder pressure.
