This design not only improves the adaptability of the tool rack, but also allows for adjustments based on different testing needs. In addition, the tool rack is equipped with a damping structure installed on the unit rack. This ensures that when the workpiece to be tested is placed on the tool rack for testing, the tool rack itself and the workpiece to be tested do not have a resonance phenomenon. This design greatly improves the accuracy and reliability of the test, as the presence of a resonance point can interfere with test results, causing data distortion. By eliminating the resonance point, the vibration test tool can provide a more stable and accurate testing environment, ensuring the authenticity and effectiveness of the test data.

[0030] The unit rack includes a top frame and a bottom frame, with the top frame located at the top of the entire structure. The bottom frame is connected to the bottom of the top frame to provide a stable foundation. The damping structure is designed between the top frame and the bottom frame to absorb and reduce energy transmission caused by external impact or vibration. To ensure that the damping structure can effectively perform its function, the damping structure is connected to the top frame and the bottom frame, so that the entire unit rack can maintain stability and functionality when facing various vibrations.
