Vibration Testing

Vibration testing is a method used to assess the vibration resistance of a product, material, or system under controlled environmental conditions. By simulating the vibrations that the object may encounter in the real environment, engineers and researchers can:

Assess durability: Determine the long-term vibration endurance of the object, to ensure longevity and avoid damage during use. Identify weaknesses: Inspect and find components, parts, or design points that are susceptible to vibration damage, and make appropriate improvements. Test performance: Evaluate the impact of vibration on the object’s performance, ensuring function and accuracy are not affected. Simulate real-world conditions: Test vibrations similar to those in transportation, operation, and usage environments, to predict and prevent damage.

Common vibration types in testing:

• Random vibration: Simulates any vibration, commonly encountered in the natural environment such as wind, waves, earthquakes.
• Sine vibration: Vibration with constant frequency and amplitude, often used to determine the resonant frequency of the object.
• Shock vibration: Simulates sudden, short and strong vibration such as collision, bumps during transportation.
• Swept sine vibration: Change the vibration frequency from low to high to determine the resonant frequency and vibration sensitivity of the object.
• Transportation vibration: Simulates vibration during transportation by truck, train, airplane,…

Data analysis:

Data collected from vibration tests is used to:

• Identify the vibration characteristics of the object such as amplitude, frequency, acceleration,…
• Assess the impact of vibration on the object.
• Compare the effectiveness of different designs.
• Predict the life of the object.

Resonance:

Resonance occurs when the vibration frequency of the excitation coincides with the resonant frequency of the object. When resonance occurs, the vibration amplitude of the object increases significantly, which can lead to damage.

In addition, some other common terms in vibration testing include:

• Vibration sensitivity: The object’s response to vibration.
• Vibration level: Vibration amplitude or acceleration.
• Vibration system: A system that includes a vibration source, amplifier, controller, and sensor.
• Vibration standard: Standards that specify vibration requirements for different products.

Important testing parameters in Vibration:

• Frequency:
• Amplitude:
• Acceleration:
• Time:
• Vibration type:
• Random vibration
• Sine vibration
• Shock vibration
• Vibration level:
• Vibration amplitude
• Vibration acceleration
• Vibration velocity

Vibration Standards:

• ISO 16750-3:2012: Applies to electric and electronic systems/components for road vehicles.
• IEC 60068-2-6: Vibration – Test methods – Part 2-6: Sinusoidal vibration with constant amplitude.
• ISO 16063-21: Vibration and shock – Guidance for the determination and assessment of the vibration sensitivity of machines.
• MIL-STD-810G: Test methods for military equipment.

Vibration Data Analysis:

• Identify vibration characteristics: Amplitude, frequency, acceleration, etc.
• Assess the impact of vibration: Fatigue, noise, etc.
• Compare the effectiveness of different designs.
• Predict the life of the object.

Overview of Vibration Testing Systems:

• Shaker: Creates vibration in the system.
  • Types: Electromagnetic and mechanical shakers.
  • Electromagnetic shakers: Use electromagnets to generate vibration force, often used for high-precision applications.
  • Mechanical shakers: Use motors to generate vibration force, often used for heavy industrial applications.
• Accelerometer: Measures vibration acceleration.
  • Types: Various types with different measurement ranges and suitable for different environments.
  • Installation: Mounted on the product or system to be tested.
• Fixture: Holds the product or system in place during testing.
  • Design: Ensures accurate and uniform vibration of the product or system.
• Controller: Controls the shaker’s operation and collects data from the accelerometer.
  • Programmable: Can be programmed to generate different vibration patterns.
  • Real-time display: Displays vibration data in real time.
• Analysis software: Analyzes the collected vibration data.
  • Identifies vibration characteristics: Amplitude, frequency, acceleration, etc.
  • Assesses the impact of vibration on the product or system.

Additional Components of Vibration Testing Systems:

• Power amplifier: Amplifies the control signal to provide sufficient power for the shaker.
• Cooling system: Reduces the temperature of the shaker during operation.
• Soundproofing system: Reduces noise generated by vibration.

Applications of Vibration Testing Systems:
