資料介紹

針對原有磁后坐電機檢測裝置標定方法存在測試誤差大、步驟繁瑣等缺點，提出用光電探測方法對磁后坐電機檢測裝置進行精確標定，并對該裝置加力板速度進行測試。該方法通過機械運動，將光信號轉換成電信號，通過濾波放大得到精確的電壓脈寬信號，即時間信號，這個時間信號就是計算用的時間，再用遮光板寬度換算，得到該裝置加力板的速度。測試結果表明：該方法測試精確、簡潔方便，是一種有效可行的方法。

Abstract:: Previous calibrating method for magnetic setback generator checking device exists shortcomings such as big error in testing and tedious procedure， optical-electric measuring and detecting method is put forward， and calibrated the magnetic setback generator checking device accurately， as well as test the velocity of gusset plat of the checking device. Herein mechanical movement is used to transfer the optical signal to electric signal ， then filter and amplify it. The voltage pulse width signal（time signal） is obtained， which is as the time for calculating， the velocity of gusset plat is calculated through the width of sun shading plate. Testing results indicate that the optical-electric velocity measuring method has the performances of measuring precision， easy and simply， and it is also efficiency and availability.
