Vibration Equipment

As specialists in dynamic testing, we provide equipment capable of exerting a 6,000 to 40,000 pound force with the capacity to perform closed-loop control from a single input to multiple channel inputs (from 2 to 32) with averaging or notched channel control. Vibration control systems can be programmed for real time monitoring, scheduled for length of time, or level scaled by dB or percentage, or scaled at various durations at different acceleration levels.

We have electro-dynamic shakers at 2-inch stroke and servo-dynamic shakers at 4-inch stroke with a range of capabilities. Most of our electro-dynamic shakers are attached with slip-plates to perform multi-axis testing. Environment Associates has both Unholtz-Dickie and Ling equipment with large size slip tables to fit most test articles and fixtures.

         

Vibration Tests

Environment Associates performs vibration tests to MIL-STD-810, RTCA DO-160, MIL-STD-750, MIL-STD-202, as well as ISTA, EN, IEC, and ASTM specifications. We also provide unique tests like gunfire, transportation packaging and NAVMAT screening.

Vibration Test Profiles

Environment Associates can setup and provide the following vibration test profiles:

Sine – Can operate swept sine or fixed frequency sine wave vibration tests that can be controlled for acceleration, velocity or displacement

Sine on Sine –Operating a mixed-mode tests with multitude sine tones.

Random –Controlled spectrum random tests with spectrally shaped gaussian amplitudes

Sine on Random – Operating a mixed mode test with sine tones on a random background

Random on Random –Operating controlled spectrum random tests with swept random tones

Shock – Standard classical shock pulses

SRS – Shock Response Spectrum analysis.

Field Data Replication – Reproduce actual acceleration waveforms measured in the field.

With over 10 million new energy vehicles in China as of June 2022, representing 3.23% of total vehicles, the shift toward electrification is accelerating globally. The power battery system is the core component of electric vehicles, and its reliability directly impacts vehicle safety. During operation, battery systems endure constant vibration loads, making vibration resistance a critical evaluation criterion.
Vibration Testing Methods
1.1 Sine Vibration
Sine vibration follows a periodic sine function, used for fixed-frequency and sweep-frequency testing. Fixed-frequency tests evaluate resonance resistance at specific frequencies, while sweep-frequency tests (linear or logarithmic) help identify structural resonance points across frequency ranges.
1.2 Random Vibration
Random vibration better simulates real-world conditions like road surface irregularities. Described statistically in the frequency domain, test parameters include frequency range (Hz), power spectral density (PSD), total root mean square acceleration (Grms), and test duration.
1.3 Mixed-mode Vibration
Combines sine and random vibration patterns (e.g., sine-on-random) to simulate complex real-world vibration scenarios.
Battery System Vibration Standards Comparison
2.1 International Standards
Key standards include USABC 1996, SAE J2380 (referenced by UL2580), UN 38.3 (transportation simulation), ISO 12405, and ECE R100-02 (European certification). These vary in test conditions, frequency ranges, and sample requirements.
2.2 Domestic Standards
GB/T 31467.3-2015 (referencing ISO 12405) was revised in 2017 to align with ECE R100-02's 3-hour sweep test. GB 38031, China's first mandatory standard, specifies SOC ≥50% and vehicle-type-specific loads based on real-world data.

Power Battery System Vibration Testing Process
3.1 Vibration Table
Electric vibration tables (5-3000Hz range) are most common, using computer-controlled feedback systems to maintain precise test conditions. Key parameters include maximum thrust, acceleration, speed, displacement, and frequency range.
Diagram of vibration table test principle for battery pack testing
3.2 Test Fixtures
Fixtures must simulate vehicle mounting conditions (flat, suspended, or press-fit) with appropriate stiffness (>test frequency range), minimal mass, and limited lateral movement to ensure accurate load transmission.
3.3 Sensor Placement
Control point sensors near mounting bolts provide feedback for drive signal adjustment, while monitoring points track battery parameters (voltage, temperature, insulation) during testing.
3.5 Case Study: GB38031 Compliance Test
A passenger vehicle battery system underwent pre-test sweeps (57.06Hz natural frequency), random/fixed-frequency vibration in X/Y/Z axes, and post-test sweeps (54.94Hz). Monitoring showed no abnormalities, with normal post-test performance.
Z-axis vibration test results for EV battery pack
At Bonnen Battery, we rigorously test power batteries to national standards, ensuring reliability against operational vibrations. Our commitment delivers high-performance solutions for evolving automotive needs.
