The system makes use of the system of hydraulic to drive the redirector’s output end and makes it to do axle motion . At the output end of the redirector there is also a system that text the output end by the hydraulic system. The system offers the load resistance to the redirector. Meanwhile , by gathering and analyzing the signals from the sensors ,the system can test the capability and the reliability of the redirector . The system is a typical mechatronic system . As requirement of the experiment , the testing parameters include the motion of the input end ,when it is idling ; the motion and the rotated corner when it is working ; the output power and the output distance ,etc . The whole system is consist of the hydraulic assistant system ,the hydraulic testing system ,the driving system for the step-motor , the frame parts ,the fastener parts ,sensors , SCM and the personal computer ,etc . The system make use of step-motor to control input end ,which can make the input motion more smooth .Taking advantage of the hydraulic system to test the output end of the redirector .Compare with the other system ,it has a light weight ,a tight volume ,and it can also achieve the stepless speed , so it has a wide scope of timing .Its transimission is smooth , so it is easier to coordinate with the electric system ,and to realize the automatic motion and operation. The system can test out the capability parameters of the redirector of the roadlouse and it can reach to a fixed precision ,so it can satisfy the requirement of the experiment .
