【詳細說明】
傳統(tǒng)的機械技術(shù)和現(xiàn)代電子技術(shù)的結(jié)合產(chǎn)生了拉力試驗機，拉力試驗機可對各種材料進行拉伸、壓縮、彎曲等多項力學(xué)性能試驗，拉力試驗機有測量范圍寬、精度高、響應(yīng)快等特點。工作可靠，效率高，可對試驗數(shù)據(jù)進行實時顯示記錄、打印。
Combined with the traditional mechanical technology and modern electronic technologyproduced the universal testing machine, universal testing machine can be of various materials tensile, compression,bending and a number of mechanical property test, the universal testing machine has wide measurement range, high precision, fast response characteristics. Reliable operation, high efficiency, but the test data aredisplayed in real time recording and printing.
電子拉力試驗機的力值測量
Electronic universal testing machine force measurement
1、力值測量
The 1 force measurement
經(jīng)過測力傳感器、放大器和數(shù)據(jù)處置系統(tǒng)來完成測量。zui常用的測力傳感器是應(yīng)變片式傳感器，當(dāng)外力作用在傳感器上時，惹起傳感器輸出電壓的變化，而傳感器輸出的電壓經(jīng)過放大器和數(shù)據(jù)處置系統(tǒng)。將電信號轉(zhuǎn)化成數(shù)值，即所施加力的大小
The force measuring sensor, amplifier and data processing system to complete the measurement. The force sensor is the most commonly used strain gauge sensor, when the external force on the sensor,arising from changes in the output voltage of the sensor, and the sensor output voltage through the amplifier and data processingsystem. The electrical signal is converted into numerical, i.e. the appliedforce
2、變形的測量
deformation measurement
經(jīng)過變形測量安裝來測量，它是用來測量試樣在實驗過程中產(chǎn)生的形變。
To measure the deformation measurement setup, it is used for measuring the specimen deformation generated during the experiment.
該安裝上有兩個夾頭，經(jīng)過一系列傳動機構(gòu)與裝在測量安裝頂部的光電編碼器連在一同，當(dāng)兩夾頭間的間隔發(fā)作變化時，帶動光電編碼器的軸旋轉(zhuǎn)，光電編碼器就會有脈沖信號輸出。再由單片機對此信號停止處置，就能夠得出試樣的變形量。
There are two chuck the installation, after a series of drive mechanismand arranged on the photoelectrical encoder mounted on top of theconnected together, when the two chuck intervals vary, the axial rotation of the photoelectric encoder, photoelectric encoder can output the pulse signal. Then the MCU to signal processing, deformation can be calculated sample.
3、橫粱位移的測量
the beam displacement measurement
其原理同變形測量大致相同，都是經(jīng)過測量光電編碼器的輸出脈沖數(shù)來取得橫梁的位移量。
The principle is the same as the deformation measurement of roughly the same, is through the measurement of photoelectric encoder outputpulse number to obtain displacement of beam.
