The Study On Comprehensive Performance Test System Control Of Gear-shift Operating Rod

The shift control mechanism of comprehensive performance test bench for domestic auto shift control mechanism integrated performance testing project status and put forward. Shift control mechanism of automobile comprehensive performance test bench is electro-hydraulic technology, electrical technology as the core, the electrical and mechanical technology, electro-hydraulic servo technology, put forward to the electro-hydraulic servo simulation technology of cable load shift control mechanisms, to electrical closed loop control technology to complete the system drive loading and measurement of new ideas. Realization of the cable in the process of moving load simulation precision simulation; shift control mechanism of friction, impact load, shift gear clearance projects such as automatic precision measurement.In the testing process, the whole process control management by computer, using a sensor to collect the test data, using Lab Windows software according to the test requirements, can be directly in real-time, on processing various test data.According to the overall plan design, this paper completed the experiment platform erection of the structure, control system and design of test system.
