Touch Haptics Test System，Automotive interior material tactile perception quality testing program system
The Touch Haptics Test System is a precision laboratory instrument designed to evaluate the tactile perception and haptic quality of automotive interior materials. The system measures key parameters such as indentation force, rebound force, sliding friction, stick-slip behavior, and surface roughness under controlled conditions, providing objective data for material selection, design optimization, and quality control. This ensures user comfort, perceived luxury, and consistent tactile experience in vehicle interiors.
Application
(1) Automotive seat surfaces: leather, fabric, synthetic leather, and composite materials.
(2) Instrument panels, center consoles, and decorative trims: soft-touch plastics, coatings, laminates.
(3) Door panels, armrests, glove compartments: tactile evaluation of touch surfaces.
(4) Steering wheels, gear knobs, cup holders: high-frequency touch surfaces.
(5) Surface treatment and coating optimization: microtexture, friction tuning, coating selection.
(6) Material development and quality control: batch testing, formula improvement.
(7) User experience and ergonomics research: quantitative evaluation of tactile comfort and perceived quality.
Standards
(1) Domestic automotive interior tactile evaluation standards.
(2) OEM internal haptic quality standards (BMW, VW, Ford, etc.).
(3) ISO surface roughness and friction standards: ISO 4287. ISO 4288.
(4) VDA tactile evaluation methods.
(5) ASTM E2530 – Haptic evaluation method.

(2) High-precision force, displacement, and vibration sensors.
(3) Environmental simulation: adjustable temperature to replicate fingertip touch.
(4) Intelligent analysis: automatic generation of curves and haptic scores.
(5) High repeatability with standardized fixtures and control system.
(6) User-friendly PC/PLC operation with automatic data recording.
Test Procedures
(1) Fix the material sample in the test fixture, ensuring a flat and stable surface.
(2) Install the test head and set initial contact pressure.
(3) Adjust temperature and testing parameters: indentation, sliding speed, friction stroke.
(4) Start the test program and monitor real-time data for force, displacement, friction, and pulse frequency.
(5) After testing, save data and generate a tactile perception report.
(6) Use protective enclosure if necessary for operator safety.
