- Purpose: To evaluate a TV's durability and reliability by simulating real-world environmental stresses. This helps identify defects related to shipping, handling, and long-term use.
- Equipment: The test uses a vibration test system, which includes a powerful electrodynamic shaker (often driven by an amplifier) and a vibration control system. Sensors, such as accelerometers, are used to measure the TV's response.
- Test types:
- Random Vibration: Simulates the chaotic, broad-spectrum vibrations of real-world environments, such as those experienced in a vehicle or during handling.
- Sinusoidal Vibration: Involves applying a continuous, single-frequency vibration that is swept up and down to pinpoint specific resonance frequencies.
- Procedure:
- The TV is mounted onto a shaker table, often the principal axes of the TV.
- A vibration profile is applied, which could involve random or sinusoidal frequencies, with parameters like acceleration, velocity, and frequency carefully controlled.
- Vibration is applied along each of the three perpendicular axes.
- The response of the TV is monitored using sensors to check for any structural damage, performance issues, or premature failures.

2000Hz Horizontal Slip Table Vibration Testing Humidity Range ≤90%
Slip Table for Vibration Shaker System A slip table in vibration testing is an auxiliary table used with a vibration exciter (shaker) to transmit motion in the horizontal direction. It's essential for testing specimens in a horizontal orientation, particularly when the specimen's orientation must be maintained throughout the test. Slip tables also enable testing of large and heavy specimens that might exceed the capacity of the shaker's vertical table.Key Functions and
