Product Overview:

Rotary Simulated Transportation Vibration Tester (Racehorse-type Vibration) simulates continuous bumping conditions during highway logistics transportation. It complies with international packaging and transportation test standards ASTM D999 and ISTA. It is used to conduct transportation reliability tests on packaging boxes of toys, electronics, home appliances, gifts, ceramics and other products, inspect the cushioning structure of packages and the vibration resistance of products, and assess the risk of damage during transportation. Equipped with a microcomputer numerical control system, the equipment operates stably with low noise and features convenient clamping. It is widely applied in quality inspection laboratories and factory production lines.

Core Product Features:

✅ High-precision CNC Control
Microcomputer numerical control timing; touch screen digital display enables real-time monitoring of vibration rotation speed. Rotation speed display accuracy: 0.1 RPM; rotation speed control accuracy: ≤±3 RPM.

✅ Low-noise Stable Operation
Adopts synchronous silent belt transmission and DC motor soft start, equipped with shock-absorbing rubber feet to reduce overall operating noise and prevent impact vibration.

✅ Quick Clamping and Positioning
The worktable is fitted with adjustable sliding rail stoppers made of aluminum profiles, enabling rapid positioning and fixing of cartons of various specifications for time-saving assembly and disassembly.

✅ No Fixation Required for Installation
Heavy-duty steel base frame with shock-absorbing rubber pads. No expansion bolts needed for fixation. The machine can be put into operation once placed on flat ground and allows easy relocation.

✅ High Cost Performance
The procurement cost of the equipment is approximately 1/10 of that of similar imported equipment from the United States, greatly cutting laboratory testing expenses.

Test Principle and Process:


The equipment generates rotary elliptical vibration via an eccentric mechanism to simulate the bumpy environment during truck transportation. Fix the test packaging box onto the aluminum profile fixture of the workbench, set the rotating speed and test duration, and the equipment will vibrate continuously automatically. It will stop automatically once the timing ends. Open the package and inspect the product for defects such as cracks, loose components and functional failures to determine whether the packaging scheme meets transportation requirements.

  Applicable Industries:
Packaging reliability tests for toys, Bluetooth earbuds / consumer electronics, household appliances, craft gifts, ceramic products and various finished product packaging boxes.
