The XYZ three-directional amplitude test machine for rackets is a high-precision three-dimensional vibration analysis device specifically designed for tennis rackets, badminton rackets, squash rackets, etc. By simulating the complex vibrations in the X, Y, and Z directions of the racket at the moment of hitting the ball, it comprehensively assesses the amplitude attenuation characteristics, resonance frequency, structural stability, and material damping performance. This equipment is widely used by racket manufacturers, professional teams, and research and development laboratories to ensure that products meet international standards such as ITF, ISO 18436, and ASTM E1876, providing scientific guarantees for the controllability, shock absorption performance, and competitive safety of rackets.
Product Overview
This machine tests the vibration curves and data of the three axes (up and down, left and right, front and back) of the amplitude, frequency, and time of the racket or the middle tube after being subjected to a certain angle of elasticity.

Core Functions
Multi-axis Vibration Testing
1. Three-axis vibration simulation:
1) Independent or combined vibration on X/Y/Z axes, frequency range 5~5000Hz (sine wave/random wave/shock waveforms), acceleration 0~50g (accuracy ±0.5% FS), simulating the vibration transmission paths of forehand, backhand, and smash strokes.
2) Amplitude range ±10mm (resolution ±0.001mm), detecting the vibration decay rate of the racket frame, shaft, and handle (a damping ratio ≥0.05 is considered excellent).
2. Resonance frequency analysis: Sweeping frequency test (0.1~2000Hz), locating the resonance points of the racket body (e.g., typical resonance frequency of tennis rackets 50~150Hz), evaluating the feel of hitting and fatigue risk.
Environmental Coupling Test (Optional)
1. Temperature and humidity cycling: Temperature range -20℃~+60℃, humidity 30%~95% RH, verifying the impact of thermal expansion of carbon fiber/vibration damping materials on vibration characteristics.
2. Dynamic load superposition: Simultaneously applying 0~100kg vertical load, simulating the pressure-vibration compound conditions during hitting.
Intelligent Monitoring and Diagnosis
1. Real-time multi-parameter collection:
1) Three-axis acceleration (±0.5% FS), displacement (laser distance measurement ±0.001mm), strain (fiber Bragg grating ±5με), temperature (infrared thermal imager ±1℃).
2) High-speed camera (10,000fps) captures the crack propagation path of the racket frame, 3D digital image correlation (DIC) technology generates full-field vibration mode cloud maps.
AI Performance Optimization: Machine learning algorithms analyze frequency response functions (FRF), recommending vibration damping design optimization solutions (such as silicone rubber handles, honeycomb shaft structures).
Data Traceability: One-click export of PDF/Excel reports (including vibration transfer functions, modal shape diagrams), supporting integration with MES/ERP systems.
Technical Highlights
1. High-Precision Excitation System:
Three-axis electric vibration table (each axis independently controlled), phase synchronization accuracy ±0.1°, dynamic response ≤ 1ms, supports multi-axis random vibration (PSD spectral density control). Modular fixture design, quick switching between tennis rackets (circular racket throat), badminton rackets (square racket throat), and other irregular structures, with adjustable clamping force from 10 to 500N. Intelligent vibration damping analysis: Built-in modal analysis software, automatically extracts modal parameters (mass, stiffness, damping matrix), and generates Campbell diagrams to predict the critical speed of the racket body.
2. Safety and Energy-Saving Design:
1) Fully enclosed soundproof cabin (noise < 65dB), emergency stop, overload protection, meeting ISO 13849 (PLd level) safety standards.

4. Standard Compliance: Built-in over 30 test procedures including ITF, ISO, and ASTM, and can generate global certification reports with one click.
Application scenarios and industry value
Production quality inspection: Three-directional vibration consistency screening of rackets before leaving the factory to ensure that the amplitude attenuation rate deviation of the same batch is ≤ ±3%.
Professional teams: Optimize the racket body's shock absorption design based on players' power application habits (baseline type / net front type) to improve the feel of ball control.
Research and development innovation:
1. Compare the vibration suppression effect of carbon fiber laminates (0°/45°/90°).
2. Verify the performance advantages of new shock absorption materials (such as graphene foam, liquid metal dampers).
Certification testing: Mandatory items such as ITF professional racket vibration standards, ASTM E1876 modal analysis, etc.
