| Abstract: | Operating principle of hydraulic retarder is briefed in the paper, and the relationship curve is given between rotor speed and braking torque obtained from bench test of the hydraulic retarder. A braking model of the vehicle driving downgrade with constant speed is established with Matlab software, and then the effect of parameters like control cycle, initial liquid charge and variation of liquid charge in each control cycle, etc. on constant speed control effect is analyzed with simulation. Road test is ca... |
