Abstract:To test photometric characteristics of motorcycle lamps automatically, a fiveaxis test equipment was developed. Working principle of the equipment was firstly introduced. Then mechanical structure of five dimension motion(X, Y, Z, A and C), control subsystem based on a motion control card and a I/O card HY6120, test subsystem built on a multifunctional photometer, and software of the equipment were developed. Afterwards an experiment of the photometric characteristics of a front position lamp was successfully performed with the equipment. Study shows that photometric characteristics of headlamps, front position lamps, rear position lamps, stop lamps and signal lamps can be automatically and efficiently tested with the fiveaxis test equipment with good accuracy. The test equipment has been used in a motorcycle manufacturing company and meets the testing requirements of photometric characteristics of motorcycle lamps well.
