Overview

It is mainly used for reciprocating fatigue test of arc spring or torsional spring in the specified torque range, reciprocating fatigue test in the specified Angle range, editing of fatigue test mode, alternating test of various modes, and static performance test of torsional spring.

Features

Central Computer Control

• The system is designed with a computer as the main body, utilizing PCI bus technology for full digital control.
• Integrates PID regulation, measurement and amplification, screen display, data acquisition, and data processing into one advanced unit.
• Offers high integration and represents a cutting-edge solution in domestic dynamic control technology.

Dynamic and Static Closed-Loop Control

• Enables closed-loop control for test force and displacement/deformation, with seamless switching between control modes.
• Supports dynamic tests (test force, displacement, frequency, signal category, and waveform control) and automatic control experiments based on user-defined spectrums (process control).
• Allows real-time adjustments of test parameters or smooth switching of control modes without interrupting the ongoing test.

Signal Generator Unit

• Provides various test waveform inputs, including:
  • Sine wave, square wave, triangle wave, trapezoidal wave, statically loaded oblique wave, and custom waveforms.

Hydraulic Control Unit

• Offers complete hydraulic control for the testing system, covering:
  • Motor start/stop, pressure mode switching (high/low), and other operational functions.

Measurement and Control Software

• Operates on the Windows XP platform, with a menu-based interface for easy operation.
