主要特点

Real-Time Down Force Control

Real-Time Down Force Control automatically maintains the programmed normal load by continuously compensating for contact wear throughout the test. Advanced closed-loop force control ensures stable contact conditions, delivering superior accuracy, exceptional repeatability, and reliable friction and wear measurements. Ideal for long-duration fretting, fatigue, and durability testing under consistent loading conditions.

Single or Dual Voice Coil Drive (1Hz to 500Hz)

An electromagnetic voice coil actuator delivers precise linear reciprocating motion from 1 Hz to 500 Hz. The FFT-1 features a single voice coil for standard testing, while the FFT-2 incorporates dual coils to double the force capacity. Both floor-standing systems provide exceptional dynamic performance for demanding, high-power fretting wear and fatigue applications.

High Accuracy Position Control from few um

High-accuracy displacement control delivers up to 1 nm resolution for precise fretting wear, fatigue, and tribology testing. Advanced closed-loop motion control provides micron-level stroke accuracy, ultra-low noise, and fast dynamic response, ensuring stable micro-motion over millions of cycles for highly repeatable and reliable wear and friction measurements.

Test Under Real-World Conditions (room to 800 °C)

Evaluate fretting wear, friction, and fatigue from ambient temperature to 800°C using advanced environmental control. Simulate real operating conditions encountered in aerospace, automotive, energy, and industrial applications to generate accurate, application-relevant data and accelerate material selection, coating development, and product reliability.

Frictionless Motion for Superior Accuracy

The frictionless magnetic flexure design eliminates bearing friction, delivering pure reciprocating motion and exceptional waveform accuracy. Intelligent closed-loop control automatically compensates for friction changes, maintaining constant stroke amplitude and ensuring highly repeatable fretting, wear, and fatigue testing over millions of cycles.

Capture Every Friction Event

High-frequency piezo force sensors and ultra-low-noise electronics measure friction in real time with exceptional sensitivity. Detect wear transitions, fretting regime changes, and early damage initiation before visible failure, delivering deeper insights into material behavior and more reliable tribological performance evaluation.

为何高负荷摩擦试验至关重要

当两个接触面在高接触压力下发生微小振荡运动时，就会产生磨擦损伤。与传统的滑动磨损不同，磨损碎屑会滞留在接触区域内，从而加剧摩擦、加速材料劣化、引发裂纹并导致部件过早失效。 诸如花键、燕尾接头、螺栓连接、轴承座和电气触点等关键部件，在重载条件下特别容易发生摩擦磨损。

要再现这些严苛的工况，仅靠标准的磨擦试验机是远远不够的。FFT-1 高功率磨擦试验机专为高负荷磨擦、磨损、摩擦和疲劳试验而设计，具备卓越的载荷能力、纳米级位移控制以及实时摩擦测量功能。 其无摩擦磁性挠杆技术、音圈驱动以及先进的环境控制选项，使研究人员能够准确模拟实际使用条件，优化材料和涂层，并从容地提高部件的耐久性。

常见问题解答

A fretting tester reproduces the small oscillatory motion — typically microns to a few millimeters — that occurs between nominally clamped surfaces under vibration. By controlling stroke, frequency, load, and environment while measuring friction continuously, it quantifies fretting wear and the damage that leads to fretting fatigue and fretting corrosion. The FFT-1 and FFT-2 are floor-standing fretting testers for high power applications.
Both share the same platform, controls, and sensors. Choose the FFT-1 for standard high power fretting testing with a single voice coil. Choose the FFT-2 when the test demands double the force range — its dual-coil drive covers the heaviest contacts.
Labs that need fretting testing beyond benchtop capability: aerospace fastener and joint programs, automotive and heavy machinery component testing, electrical connector development using ECR, and research groups studying crack initiation with acoustic emission under high-load fretting contact.
The FFT-1 uses a single voice coil drive; the FFT-2 uses a dual-coil drive that doubles the force range. Platform, controls, position resolution, and sensor options are otherwise identical.
The FFT-M is a compact benchtop fretting tester. The FFT-1 and FFT-2 are floor-standing, high power machines for larger forces and heavier fixtures, built on the same voice coil and flexure principles.
Displacement control reaches 1 nm resolution with micron-level accuracy and very low noise. The controller compensates for friction changes in real time to keep the stroke on target throughout the test.
Yes. High frequency piezo sensors measure friction in real time, with ultra low noise amplifiers resolving small friction changes that mark wear transitions and fretting regime shifts.
Yes. An optional acoustic emission sensor detects the onset of cracks as they form, correlating damage events with cycle count, friction, and stroke data.
Magnetic flexures remove rolling and bearing friction from the motion path, so the measured friction comes from the test contact alone and stroke control stays stable at micro-motion amplitudes.
Yes. Customizable liquid containers support submerged tests, and environmental control covers fretting wear studies across a wide range of temperature.
