| 摘 要： | 速度特性图、示功图是车辆减振器的重要动力特性参数,设计了一种机械式速度试验机。为克服传统的机械式试验机磨损快,滑块质量过大的缺点,设计了特殊的润滑与密封装置。同时广泛采用弹性铰链以消除联结间隙,大大降低了噪声。本机还设计了慢速装置(0.05m/s)以测量滑动摩擦力。用试验机对三轮汽车减振器进行实测,结果表明系统测量可靠,操作快捷、方便。

| Abstract: | Velocity characteristics and indicator diagram are important parameters of shock absorbers.Based on the comparison of various schemes of the structure,a mechanical test machine is designed.A special lubricating device is designed to overcome the default of high friction of traditional mechanical machine.And elastic hinges are applied to avoid the gap of joints,thus greatly reduce the noises.Also,a low-speed device(0.05m/s) is designed to measure the slip-friction of absorber.Furthermore,a computer data acquisition and control system is designed for the test machine.A kind of shock absorber has been tested by machine,and the test results prove that the test machine is high-quality,and its operation is quick and convenient. |
