传统的机械技术和现代电子技术的结合产生了万能试验机，万能试验机可对各种材料进行拉伸、压缩、弯曲等多项力学性能试验，万能试验机有测量范围宽、精度高、响应快等特点。工作可靠，效率高，可对试验数据进行实时显示记录、打印。
Combined with the traditional mechanical technology and modern electronic technology produced 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.
电子万能试验机的力值测量
Electronic universal testing machine force measurement
1.力值测量
The 1 force measurement
经过测力传感器、放大器和数据处置系统来完成测量。最常用的测力传感器是应变片式传感器，当外力作用在传感器上时，惹起传感器输出电压的变化，而传感器输出的电压经过放大器和数据处置系统。将电信号转化成数值，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.变形的测量
2 deformation measurement
经过变形测量安装来测量，它是用来测量试样在实验过程中产生的形变。
To measure the deformation measurement setup, it is used for measuring the specimen deformation generated during the experiment.
该安装上有两个夹头，经过一系列传动机构与装在测量安装顶部的光电编码器连在一同，当两夹头间的间隔发作变化时，带动光电编码器的轴旋转，光电编码器就会有脉冲信号输出。再由单片机对此信号停止处置，就能够得出试样的变形量。
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.横粱位移的测量
3 the beam displacement measurement
其原理同变形测量大致相同，都是经过测量光电编码器的输出脉冲数来取得横梁的位移量。
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.
