Constructional Design The Automobile Test-bed System Of Shifting Mechanism

The shifting mechanism of the test-bed system for the current testing equipment to shift the existence of the low measurement accuracy, detection of slow, low degree of automation, performance, instability, inconvenient to operate and so on, design a test bed that have a control high precision, simple operation, high automation, performance and stability characteristics. The closed-loop control of electrical servo test system technology, the closed-loop control of servo-pneumatic system technology and the closed-loop electro-hydraulic servo control system technology are used in the system. DSP is also used in the system. The purpose of this system is to complete the static and dynamic strength of selected files and impact strength test.The idea of the source designation and realization of the specific ways detail in the test about the shifting mechanism and hydraulic power supply.
