1.The measurement control system uses the high-performance motion controller from National Instruments (NI) as its core component, with functional units templated and standardized, featuring flexible configuration, strong interchangeability, and ease of after-sales service;
2. Control Methods: Load and displacement, two fully digital closed-loop real-time control methods, with disturbance-free switching; three actuators can be loaded individually or simultaneously, capable of multi-channel parallel independent data measurement, display, and storage;
3. Loading Time: The time required to load to a specified value under displacement control is referenced to the speed range of the servo actuator, while under load control, the fastest loading time to a specified value is 2 seconds, with no upper limit;
4. Holding Time: The holding time for loading to the target is infinitely adjustable, with a minimum of 1 second and no upper limit;
5. Data processing method for test curves can be integrated with test operation parameters to form an overall test module, offering flexible combinations and easy access, enabling the saving and retrieval of all parameters;
6. Safety protection functions include overload protection and software-set protection measures, ensuring the safety of personnel and equipment.
7.Load device The load device is installed on three movable crossbeams. The load device is mainly composed of load actuator, load sensor, actuator frame, limit device, locking device and so on.This test bench is a 3-channel test bench, with 3 sets of load devices, which are installed on three movable crossbeams respectively.
8.Servo electric cylinder The servo electric cylinder system is used to receive control electrical signals and control the movement of the electric cylinder according to the control information, which is the core of the action execution part of the whole equipment.
9.The load sensor adopts the spoke sensor, which is specially designed for both tension and compression. It can meet the requirements of different precision tests, with high accuracy, small distortion, stable performance, good lateral force resistance, wide range of measurement and convenient installation and use.
10.Measurement Control System The measurement control system uses a multi-function board card from NI Corporation of the United States. It is a rugged, reliable, high-performance industrial-grade control card with industry-standard certification. It is particularly suitable for applications requiring waveform acquisition, high-speed control, or signal processing.
