3. Functional characteristics of testing machine:
The testing machine is mainly composed of a main machine, a microcomputer control unit, a strong current control unit and test accessories.
The main machine adopts welding structure design and manufacturing, horizontal loading design, large drum adopts international standard design, the design diameter of 1707.6mm, as far as possible to simulate the road condition, excitation speed regulating motor to drive the drum to achieve stepless speed regulation, to realize the test of different driving speeds, loading bracket adopts low-damping linear element transmission, servo motor drive closed-loop control. The load sensor completes the measurement of applied load, so as to realize the closed-loop control of fatigue test load and the emergency shutdown function of fatigue damage.
The test process is automatically controlled by the computer. After the test load and test mileage are set by the computer, the computer automatically controls the servo motor to load and automatically stops when the test mileage is reached.
Computer control system with safety protection, overload, tire, wheel damage and other accidents can be automatically unloaded and shut down.
Equipped with strong current control box, complete the drive control of excitation speed regulating motor, with power on, off, motor start, stop, speed increase or decrease and other operation functions.
Microcomputer control unit, configuration computer, computer for Lenovo brand machine, mainstream configuration, computer built-in signal amplification A/D conversion board, complete sensor signal amplification and signal analog-to-digital conversion, computer software for WINDOWS platform software, with test parameter setting, dynamic test waveform display, test data storage, output test report and other functions.
The printer prints the test report.
