速度测试仪是汽车实验室不可缺少的设备,如汽车碰撞试验的汽车碰撞速度测试,汽车座椅头枕冲击试验的冲击速度测试,汽车转向机构冲击试验的冲击速度测试,汽车电动门窗升降机的升降速度测试,以及汽车四门两盖疲劳试验的关门速度测试等。文中介绍的手持式测速仪就是根据汽车试验需要开发的,同时还研发了一套独特的转盘型标准速度校对方法,非常容易推广使用。
Speed tester is indispensable in the automotive laboratory equipment, such as car crash test car crash speed test, car seat headrest impact test impact speed test, car steering mechanism impact test impact speed test, lift the car electric windows and doors lift Speed test, as well as the car four-door fatigue test closing speed test. The article describes the hand-held speedometer is based on the needs of automotive testing developed, but also developed a unique dial-type standard speed proofing method, very easy to promote use.
