Packaging Transportation Simulation Vibration Tester China Manufacturer
Rotary Type Vibration Test Machine is intended to simulate the vibration during cargo transportation to figure out whether the package and the content inside can resist these conditions.
The eccentric bearing inside the machine is able to produce an elliptical motion track during rotation, generating the fixed displacement at one-inch peak to peak and at a predetermined frequency.
Although It is a non-simulation Integrity performance vibration test, It is widely used to test the strength of the combination of products and the package and the robustness of the package.
It effectively helps people in determining the strength of the interior goods during transportation and the protective ability of the package to the contents when subjected to rotatory vibration at a constant frequency. It can be used as a single test or as part of a series of tests.
Test Principle
A package sample with the same weight as that in practice is placed on the vibrating table and clamped firmly with the guide rails and four edge fixtures to prevent it from moving during the test.
The table shakes the sample at a low-frequency oscillation with a fixed displacement. The temperature and humidity conditions, test duration, vibration frequency, and sample placement state are all predetermined.
If necessary, a specific load can be added to the test sample to simulate the condition that the package is at the bottom of a stack.
The influence of the simulated working conditions obtained in the laboratory on the goods is used as the basis for the evaluation of the product and the packaging.

What’s the Significance of Performing Rotary Vibration Test on the Package Box?
In our daily life, no matter what the product is, it will inevitably suffer vibration during transportation. The difference is just the magnitude of the vibration. The influence arising from it is different according to different products.
For example, the glass and earphones are also transported by a vehicle. Obviously, the glass is more sensitive to vibration than the earphones in the process of shipment and has stricter requirements for the vibration level.
In order to choose a safe and suitable transportation method and eliminate the loss caused by transportation, we must find a device that can conduct packaging vibration testing.
Usually, the packaging vibration testing is carried out using a rotary vibration test machine or random vibration test machine.
Both can reproduce the vibration that may be encountered during the transportation journey, so as to detect whether the package and content will be damaged, and then try to find a reasonable packaging solution.
The benefits of rotary vibration testing:
- Helps analyze the strength of the product packaging, evaluate whether the existing packaging can protect products inside during shipment, so as to find a better packaging solution.
- Able to reduce product damage caused by defective packaging, thus to save unnecessary costs.
- Conducive to satisfying your customers. When your customers receive a good package and products in good condition, they will feel particularly pleased, and give you a good comment.

FAQs
The rotary vibration tester has a constant amplitude and is suitable for products with a single package. It is mainly to simulate bumps and vibrations during vehicle transportation to determine the damage to the products. In case of different road conditions such as bumps, uphills, downhills, turns, etc., the product collides with the product in the packaging box, and the product collides with the box, so as to further improve the product quality and product packaging quality.
The vibration of the electromagnetic vibration tester derives from the movement of the energized conductor under the action of electromagnetic force in the magnetic field. An exciting force is generated when the alternating current signal is passing through the moving coil in the magnetic circuit, and a vibration motion is generated in the magnetic circuit at the same time, which is similar to a speaker.
Its cost is much higher than the rotary vibration tester. The electromagnetic vibration tester is suitable for products that require high frequency.
This electromagnetic shaker is used to detect early failures, simulate actual working conditions and structural strength.
- Must use the power supply specified by the manufacturer. It is strictly forbidden to use unmatched voltage.
- When installing the sample to be tested, it must be mounted firmly. Place the package in the center as much as possible. If the sample is found to be unclamped during the test, it should be re-clamped after stopping the machine. Operation is strictly prohibited when the machine is not stopped.
- The bottom area of the carton sample cannot exceed the edges of the work table.
- The weight of the test sample should not exceed the maximum load. If with long-term overload use, It may lead to failure and shortened life of the testing machine.
- Adjust the speed governor to the “0” position before starting to prevent the circuit from burning out. After turning on the power, slowly rotate the frequency adjustment knob to make the table reach the required oscillation frequency.
- This transportation vibration tester is a used to test on the packaging box after the product is packaged. Do not directly perform the product vibration test to avoid scratching and damaging the sample.
- The control box is a power control component and must not bear heavy objects and severe vibration.
- Both the control box and the table have heat dissipation holes, which should not be blocked by any objects and debris.
- When the machine is found to have abnormal sound during operation, immediately stop it for inspection, or contact us for handling before it continue to run.
Don’t worry, we have according solutions for your situation.
Considering the tall packing boxes, for example the refrigerator box with a small base area, but a relatively high height. It is liable to topple and fall in vibration test if fastened by our regular guard rails.
In order to prevent this from happening, we will extend the guard rails to a higher position to match the height of your package and configure with 4 more clamps (8 clamps in total with 2 layers) to hold the carton firmly.
In a word, the height of guard rails can be tailored on the basis of your package height.
Sure, we can tailor a table with the suitable length and width for you to accommodate your package. You just need to tell us the accurate size of your package to be tested when inquiring. Our sales specialist will submit a proposal only fits your requests.
Rotary Motion is a constant elliptical motion trajectory.
The shaking table is attached to the eccentric bearing. When the eccentric bearing rotates under the drive of the motor, the entire plane of the test platform will cyclically move in the upper, front, lower and back directions to draw an elliptical trajectory, which is also similar to the up and down trajectory of a horse’s body when it is running.
When the operator adjusts the speed of the rotary motion, it is equivalent to adjusting the traveling speed of the entire vehicle or ship.
This rotary vibration testing equipment is able to simulate the scenes of the collision or squeezing between products, and between products and the packaging box containing them when the vehicle loaded with goods is subjected to bumping, uphill, downhill, turning or under other road conditions.
There are no strict restrictions on the products in the packaging box, and almost all products can be accepted. But in practical applications, packaging vibration testing is mainly suitable for fragile and easily broken or deformed items, such as pottery, ceramics, LED lights, glass, glass products, computer or mobile phone displays, fruits, eggs, etc. If you are not sure whether it is applicable to your product, you can always “CONTACT US“, our sales specialists are happy to answer any questions from you.
