Simulating the Real World: Why "3D Torsion Testing" is Critical for Robot Cable Longevity

Simulating the Real World: Why "3D Torsion Testing" is Critical for Robot Cable Longevity

January 15, 2026

In the dynamic world of industrial automation, robotic arms rarely move in a single plane. They twist, bend, and rotate simultaneously. For the high-flexible cables powering these machines, this creates a complex stress environment known as "3D Mechanical Stress."

Standard testing machines often test bending or torsion separately. However, to truly guarantee that a cable won't fail inside a multi-axis robot, you need to simulate both forces at the same time.

Today, we introduce the solution for this exact challenge: The TH-5814 Cable 3D Torsion Testing Machine by Suzhou Tophung.

What is 3D Torsion Testing?

The TH-5814 series is engineered with a unique composite torsion-bending combination structure. Unlike traditional testers, this machine fixes the upper end of the cable sample to a bending fixture while the lower end is secured to a rotating platform.

This setup allows for a synchronous test, subjecting the metal wire to repeated torsion and bending actions simultaneously. This is the only way to accurately detect plastic deformation defects that occur under complex, real-world usage.

Key Features of the TH-5814 Series

1. Compliant with Global Standards For manufacturers exporting globally, compliance is key. The TH-5814 is suitable for high flexible cable testing requirements according to major international standards, including TUV 2TFG 2577, UL RP5770, VDE-PB-0022, IEC60227-2, and CRIA 0003.

2. High Efficiency & Throughput Time is money in the laboratory. The TH-5814 features 3 test stations, allowing you to test multiple samples at once.

  • Test Speed: Adjustable from 0 to 60 times/min.

  • Torsion Angle: 0° to ±720°.

  • Bending Angle: 0° to ±120°.

  • Flexibility: The torsion and bending starting angles can be synchronized or set independently via the PLC touch screen.

3. Intelligent Failure Detection Testing until destruction is useless if you miss the exact moment of failure. The TH-5814 can equipped with 30 pairs of monitoring interfaces.

  • Real-time Monitoring: The device can be extended to multi-channel resistance monitors to track connectivity online.

  • Instant Alarm: If a line break occurs, the system triggers a sound and light alarm, and the interface displays a detailed fault description.

4. Precision Accuracy Data reliability is ensured by high-precision sensors and original 6-point calibration technology. The measurement accuracy is better than the national 0.5 level (the highest level), with a resolution of up to 1/500,000.
