In recent years, in the theoretical analysis of gear transmission, in addition to the new achievements in applied mathematics, mechanics, materials and design theory, The further development of gear transmission technology and the solution of existing problems depend on the application of advanced test technology to a great extent. Based on the performance index of gear transmission and the type of gear test device, a test and test system for comprehensive performance of gear transmission is proposed in this paper. The transmission efficiency, bearing capacity and temperature rise of gear transmission system are carried out on a power open test rig. Vibration and noise testing. The main work of the thesis includes the following aspects:. The main contents of this paper are as follows: 1. The advantages and disadvantages of open test bed, mechanical closed test bed and electric closed drive test bench are analyzed. The common testing contents and testing principles of gear and gear transmission are discussed, which lays a foundation for the design of gear transmission test system. (2) this paper puts forward a kind of comprehensive test and test system for gear transmission, and develops its function realization and overall design research. According to the maximum power and torque transmitted by the expected test object, the driving device and loading device of the test bed are selected. And select the corresponding test instrument, build the gear drive comprehensive test bench. 3According to the performance requirements of the test system, the design of the whole structure scheme of the test and test system is carried out, and the structural analysis of the key parts of the test bench is carried out, so that the overall performance of the test bed can reach the target requirements. 4. The mechanism and transmission path of vibration and noise in gear transmission system are studied. The representation of vibration signal of gear transmission system is analyzed theoretically, and the corresponding vibration and noise test module is configured for the test system. (5) taking vibration and noise test as an example, using BK vibration and noise testing system platform to test vibration and noise of a certain type of automobile transmission under different working conditions, using dynamic analysis software and spectrum analysis technology to analyze the test data. This paper provides the experimental identification basis for the vibration and noise source of gear transmission, and verifies the feasibility of gear transmission performance test on the developed test bench through the practical application test in engineering.
