Before using any test machine, we should fully understand the performance of the product and fixture, so as to better realize man-machine running-in during the operation process. In order to improve production efficiency. Next, we will introduce to you the performance characteristics of the electronic universal testing machine, to help you further understand the equipment.

1. Ball screw, which drives the sensor of electronic universal testing machine, will directly affect the maximum deformation and elongation after breaking if the screw has clearance. At present, some of the screw rods of electronic universal testing machines on the market are T-shaped ordinary screw. In this way, the clearance is relatively large, and the friction force is relatively short. The screw used in Yihuan Instrument Science and Technology is German Yourief high precision clearance-free ball screw. The hardness of surface quenching is HRC58-62, and the service life can reach several decades. And the accuracy is guaranteed to remain unchanged.
2. The transmission system of electronic universal testing machine. At present, some of the transmission systems of testing machine in the market adopt reducer and some adopt ordinary belt. The main drawbacks of these two transmission modes are that the former needs regular lubrication, while the latter can not guarantee the synchronization of transmission and influence the test results. The drive system of the test machine of open source instrument adopts full arc synchronous belt to decelerate, which guarantees the synchronous accuracy of transmission, high transmission accuracy, high efficiency, stable transmission, low noise and long service life without maintenance.
3. The force sensor of the testing machine, because the quality of the sensor determines the accuracy and stability of the testing machine. At present, the small force sensor of the tension machine on the market generally uses S-type sensor, the spoke-type sensor, and the internal resistance strain gauge. If the precision of the strain gauge is not high or the anti-aging ability of the rubber used for fixing the strain gauge is not good, or The poor material of the sensor will affect the accuracy and service life of the sensor. The imported sensor adopted by our company is the American force sensor manufactured by the world famous sensor manufacturer. The sensor has high precision, good linearity, very stable performance, and will remain unchanged for decades.
4. The power source (motor) of the electronic universal testing machine is also called motor. At present, some testing machines on the market adopt ordinary three-phase motor or variable frequency motor. This kind of motor adopts analog signal control, which has slow control response, inaccurate positioning and narrow speed range. If there is high speed, there will be no low speed or low speed, there will be no high speed, and the speed control is inaccurate. The motor used is Panasonic digital AC servo motor. The control mode adopts full digital pulse control, and the speed range is wide. It can reach 0.001-1000MM/MIN. The control position is accurate, the response is fast, and 0.01 seconds can be added to the full speed. The motor can ensure the full range speed control is accurate and the service life is long. It can last for decades without maintenance.
5. The measurement and control system of electronic universal testing machine (i.e. software and hardware). At present, most of the measurement and control systems of pulling machines in the market are controlled by 8-unit single-chip computer. The sampling rate is low, and the anti-interference ability is poor. The other is AD converter, if the digit of AD converter is low resolution. Then the measurement will not be accurate. The company's measurement and control system uses the world's most advanced 32-bit ARM technology to develop the controller HytestV6.0. This controller is based on 32-bit ARM platform, and runs the company's time-to-time multi-task operating system, is more stable program operation, system more stable. Sampling rate can reach 200 times per second. With 24 bits of high precision, low noise and high speed AD converter, the whole measurement and control system can be more precise and stable to control the whole test process. The software of the host computer is a full digital three-step loop control software developed over two years. There are two control modes a. PID control and regulation mode B. Modal Lake Control and regulation mode (the first in the industry). The whole test process can be controlled by constant force, constant displacement, constant deformation, low frequency fatigue and program arbitrary control.
In summary, it is for the performance characteristics of electronic universal testing machine which are related to the introduction, the majority of users in the selection process can be combined with their own situation to choose. Only after having a certain understanding of it, users can choose the products and devices that are more suitable for them. If you have this demand, please call for consultation.
