Introduction to the main machineThe machine consists of a working platform, a servo motor and reducer imported from Japan, a high-precision dynamic torque sensor, a load sensor, a fixture, a static torque sensor, and a guide rail.The loading mechanism uses a servo motor to drive the reducer to apply torque to the sample. The torque value and clamping load of the sample are measured by the sensor. At the same time, the torsion angle is detected by the photoelectric encoder. The detected signal is transmitted to the measurement control system to complete the measurement of the sample torsion index and the drawing of the curve.-Safety load: 150% rated load;-Excellent linearity under forward and reverse load, linear error 0.3% FS;-Dynamic load accuracy is 0.3% of indicated load.-The flange sensor itself has a concentric design structure.-The flange torque sensor is much shorter than the shaft torque sensor, so it is less affected by its own weight 7.2 Controller IntroductionThe electrical core is the NAICE TEST controller specially used for the test machine by our company. It is a controller developed based on DSP test technology to meet the GB/T228.1-2010 test. It has full digital control, multi-channel acquisition and other functions. The system is powerful, accurate in data processing, simple to operate, and easy to use and maintain.NAICE TEST controller performance features:1. NAICE TEST uses FPGA chip, embedded with customized ARM core, full-path parallel operation, and achieves the computing workload of a single-core CPU above 1GHz with a 100MHz computing clock speed. External communication uses 100M adaptive Ethernet TCP/IP protocol with RJ45 interface. It has strong anti-interference ability, long-term stable operation, and fast closed-loop speed.2. NAICE TEST integrates data acquisition, closed-loop control, and I/O operation, and can be applied to dynamic testing machines with closed-loop control requirements. It can be directly connected to the host computer software through high-speed Ethernet. It is widely used in various test instruments that require high-speed acquisition and control, such as automotive fatigue, fastener analysis, conventional fatigue, lateral vibration, and electro-hydraulic servo.3. NAICE TEST is a true multi-task parallel processing system. It uses FPGA to parallel and synchronously process all closed-loop control data, which can ensure that the system has high response speed, high control accuracy, smooth control switching, accurate data acquisition and synchronization.4. NAICE TEST displays the PID closed-loop adjustment effect on the debugging software with a curve graph, and intuitively sees the adjustment effect of the PID parameters. During closed-loop control adjustment, the control effect curve after changing the PID parameters is displayed on the debugging software, making PID adjustment real and simple.5.
