A universal online detection test-bed of transmission is developed

the automatic shift of transmission is realized by the test-bed using the industry control computer control mechanical arm.Data analysis model is established based on neural network algorithm

and neural network training is completed by the gradient descent method.The network can discriminate transmission quality successfully.The establishment of expert system is good to solve nonlinear problems of shift strategy and determine the gear parameters accurately.The fatigue test

transmission efficiency test and other test items can be completed by the test-bed.The system has good reliability

high intelligence and has the good application value in the aspect of automatic detection and fault diagnosis of gearbox.
