[Abstract]:Gears, as parts of motion and power transmission, are widely used in automobile, ship, aerospace and other fields. With the development of science and technology, More and more requirements for gear quality are put forward. A portable gear transmission noise testing system is developed in view of the difficulties of high dependence on workers' experience in the field detection of gear transmission noise. Used for the field measurement of gear transmission noise. The main work is as follows:. A scheme of embedded gear transmission noise test system based on ARM(Advanced RISC machines and DSP(Digital Signal processing technology is presented. A prototype of gear transmission noise testing system is developed. The hardware part of the system mainly includes gear noise signal acquisition module, low-pass filter module and AD conversion module, timing control module DSP control and signal processing module arm processing and graphics display module. Communication and storage module and instrument electric box etc. The software part of the system is designed. The time sequence control program and signal processing program of FPGA(Field-Programmable are programmed. The communication program includes the graphical interface display program of arm and so on. The noise signal is collected by DSP and FPGA. Then the data of transmission noise signal is transmitted to ARM through communication module to realize the graphic display of noise signal. The performance test and experimental verification of the developed gear transmission noise test system are carried out. The experiment includes the testing experiment of each module of the system and the testing experiment of the whole system. The experimental results show that the performance of the developed gear transmission noise test system is good. It can be used to analyze the transmission quality of gears.
