| Abstract: | In order to control the load of hydraulic power steering pump according to the test specifications in engine test ,a measurement and control system for a loading device was developed .The system was composed of measurement and control u-nit with a 16 bit microcontroller ,servo motor driver and industrial control computer .Using Ethernet to realize the communica-tion between upper and lower computer ,the parameters such as the oil pressure ,oil temperature and steering resistance were measured in real time .The synchronization time was defined according to the start flag from engine test bench system and the steering pump load was adjusted by controlling the angle of power steering gear .The test results show that the measurement and control system can meet the requirements of continuous loading for the steering pump in engine test. |
