Vibration Tests
Vibration tests are critical validation procedures performed to evaluate the resistance of products against shock and vibration conditions they may experience throughout their lifetime. During these tests, products are subjected to controlled vibration or shock at specific frequencies (cycles per second), amplitudes, and acceleration levels.
Potential issues observed and analyzed during vibration tests include:
* Loosening of fasteners
* Cracks or damage on structural components
* Intermittent contacts in electronic parts
* Resonance-induced structural failures
Our high-capacity shaker system can be operated in combination with an environmental chamber. With this capability, vibration tests can be performed under temperature conditions ranging from -70 °C to +180 °C, allowing simultaneous mechanical and environmental stress evaluation of the products.
With our test infrastructure, the following can be conducted:
Vibration tests in the 0–2600 Hz frequency range,
Up to 54 kN vibration force,
Up to 108 kN mechanical shock force,
By adjusting the shaker system position, multi-axis tests can be performed in X, Y, and Z directions.

Sine Vibration Test
The sine vibration test is performed by exposing the product to vibration within a defined frequency range (5–2600 Hz) in a gradual manner. This allows identification of the product's resonance frequencies—where vibration response is amplified the most—along with critical regions. The resulting data is then used to support design improvement and optimization.
Modal Test
In the modal test, vibration is applied to the product using a shaker, and accelerometers are used to determine the product's resonance frequencies.
Random Vibration Test
The random vibration test simulates the mixed vibration conditions that a product may encounter during real-life operation (road conditions, transportation, on-vehicle vibrations, etc.) in a controlled laboratory environment. After the test, the product is examined for cracks, loosening, fractures, or performance degradation to assess structural integrity and reliability.
Shock-Impact Test
The shock test measures the product's resistance to sudden impacts and drops. These tests can be performed at force levels up to 108 kN.
Combined Vibration + Temperature Test
The combined vibration + temperature test is an environmental endurance test in which the product is simultaneously exposed to vibration and rapid temperature variations. Vibration is applied under temperature conditions ranging from -70 °C to +180 °C, allowing evaluation of vibration resistance under thermal cycling conditions.
Sine-on-Random Vibration Test
The sine-on-random vibration test is an advanced vibration method in which the product is exposed simultaneously to both real-life mixed vibrations (random) and defined frequency excitations (sine). Testing can be performed at high acceleration levels under temperature cycles ranging from -70 °C to +180 °C.

Salt Spray Test
The salt spray test is one of the most widely used accelerated corrosion test methods. In this test, samples are exposed to a corrosive environment created by continuously spraying a salt solution (typically 5% sodium chloride – NaCl) under controlled temperature and humidity conditions. The purpose is to evaluate
coating quality, corrosion resistance, and surface protection performance
.
After testing, the durability of protective layers such as paint, coating, galvanizing, chrome, and nickel against rusting, blistering, cracking, or peeling is examined. This provides insight into how long a product can withstand real environmental conditions.
