What are the main components that affect the performance of the material tensile tester? What are the main components that can affect the performance of the material tensile tester in order to better select the tensile tester? Suzhou Puyi provides the following for reference 2. Transmission system: The transmission system of the electronic universal material testing machine. The transmission system of the pulling machine used earlier on the market has the use of a speed reducer and an ordinary belt. The main drawbacks of these two transmission methods are: the need to add lubricant regularly before the Those who do not guarantee the synchronization of the drive will affect the test results. In order to consider the stability of the equipment and test accuracy, most of the market today uses arc tooth synchronous belt wheel deceleration to ensure the synchronization accuracy of the transmission, high transmission accuracy, high efficiency, smooth transmission, low noise, no maintenance and long service life. 3. Sensor: The accuracy and linearity of the sensor directly determine the accuracy and stability of the test data of the yield strength of the ribbon. At present, the material strength tester on the market uses a S -type sensor for the small force , and the value is generally used for the general purpose. Radial sensors, the internal sensor is generally resistive strain gauges, if the accuracy of the strain gauge is not high or the resistance of the fixed strain gauge with anti-aging ability is not good or the sensor material is not good will affect the accuracy and service life of the sensor. 4. Motor: The power source ( motor ) of the tensile testing machine is also called the motor. At present, the material tensile testing machine on the market adopts ordinary three-phase motors or variable-frequency motors. This kind of motor adopts analog signal control, slow control response, and inaccurate positioning. The general speed range is narrow. There is no speed at high speed or no speed at low speed, and speed control is inaccurate. Using AC servo motor, the control method adopts all-digital pulse control, wide speed range, up to 0.001-1000mm/min , accurate control and positioning, fast response, 0.01 seconds can be added to full speed, the motor can guarantee full-scale speed control accuracy , And long life. 5 , measurement and control systems: test machine measurement and control systems ( ie, software and hardware ) , the current market, some of the tensile machine measurement and control system using 8 -bit microcontroller control, low sampling rate, and poor anti-interference ability, the other is the AD converter If the AD converter has a low resolution, the measurement will not be accurate. The measurement and control system shall adopt a controller developed by 32 -bit ARM technology. This controller is based on a 32 -bit ARM platform with a sampling rate of up to 200 times per second, plus a 24 -bit high-precision low-noise sound high-speed AD converter. The measurement and control system has higher precision and more stable control of the entire test process. The measurement and control software is the latest development of a new generation of all-digital three-closed-loop control software. The entire test process can achieve constant force control, constant displacement control, constant deformation control, low frequency fatigue control, and program arbitrary control. To sum up the above points, we hope to provide you with a reference when you are purchasing a tensile testing machine, and to select a tensile testing machine that is more suitable for your product.
