Electronic universal testing machine force measurement

1.力值測量

The 1 force measurement

經(jīng)過(guò)測力傳感器、放大器和數據處置系統來(lái)完成測量。常用的測力傳感器是應變片式傳感器，當外力作用在傳感器上時(shí)，惹起傳感器輸出電壓的變化，而傳感器輸出的電壓經(jīng)過(guò)放大器和數據處置系統。將電信號轉化成數值，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

2 deformation measurement

經(jīng)過(guò)變形測量安裝來(lái)測量，它是用來(lái)測量試樣在實(shí)驗過(guò)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(gè)夾頭，經(jīng)過(guò)一系列傳動(dòng)機構與裝在測量安裝頂部的光電編碼器連在一同，當兩夾頭間的間隔發(fā)作變化時(shí)，帶動(dòng)光電編碼器的軸旋轉，光電編碼器就會(huì )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

3 the beam displacement measurement

其原理同變形測量大致相同，都是經(jīng)過(guò)測量光電編碼器的輸出脈沖數來(lái)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.
