1. Introduction
In the modern context of industrial and technological development, ensuring the safety and reliability of products across diverse transportation and usage environments is of paramount importance. For batteries and related products, the UN 38.3 test standard has emerged as a globally recognized and authoritative norm. Its primary objective is to safeguard the safety of battery - containing devices in scenarios such as air transportation. The 10kN vibration table, as a specialized testing apparatus, harnesses its robust sinusoidal vibration testing capabilities to precisely meet the stringent requirements of the UN 38.3 test standard. It offers efficient and reliable testing solutions to battery manufacturers, electronic product producers, and various relevant testing institutions, playing an indispensable role in upholding product quality and transportation safety.
2. Key Technical Features
2.1 Robust Vibration Output Capability
- 10kN Peak Force: This vibration table is capable of generating a peak force of up to 10kN. This substantial force is sufficient to drive test samples of various sizes and weights during sinusoidal vibration testing. Whether it is a small button battery or a large - scale power battery pack, the 10kN force ensures that test samples receive stable and standard - compliant vibration excitation within the specified frequency range. This remarkable force performance enables the vibration table to simulate the vibration intensities likely to be encountered in various actual transportation and usage environments, laying a solid foundation for accurately assessing the structural integrity and reliability of products.
- Broad Frequency Range Coverage: The frequency range of the vibration table can span from as low as a few Hertz (Hz) to as high as several thousand Hertz, typically covering the frequency interval of 1Hz - 3000Hz. This wide - ranging frequency coverage allows for the simulation of vibration frequency characteristics associated with different transportation modes (such as road, rail, and air) and diverse usage scenarios. For instance, during air transportation, the vibration frequencies of aircraft engines and the vibrations of the fuselage caused by airflows can both impact batteries and related products. The 10kN vibration table can precisely adjust the frequency to simulate these complex vibration environments, comprehensively detecting the performance of products at different frequencies.
2.2 Precise Sinusoidal Vibration Control
- High - Precision Waveform Generation: When conducting sinusoidal vibration testing, the vibration table can generate an extremely accurate sinusoidal waveform. Through advanced digital control technology and a precise sensor feedback system, the distortion of the sine wave is kept to a minimum, generally controllable within 1%. This means that the vibration excitation received by the test sample closely aligns with the ideal sinusoidal vibration pattern, thus guaranteeing the accuracy and repeatability of test results. For battery products, precise sinusoidal vibration testing can accurately detect the performance changes of components such as internal electrodes and electrolytes in a stable vibration environment, facilitating the discovery of potential structural defects and safety hazards.
- Flexible Parameter Adjustment: Users can flexibly adjust various parameters of the vibration table, including vibration amplitude, frequency, and acceleration, in accordance with the UN 38.3 test standard and the specific characteristics of products. The vibration amplitude can be finely adjusted within a wide range to meet the requirements of different test scenarios for vibration intensity. For example, when simulating the bumpy vibrations during road transportation, an appropriate vibration amplitude can be set according to the actual road conditions; when conducting air transportation simulation tests, the amplitude can be adjusted based on the vibration data during aircraft flight. The adjustment of frequency and acceleration is equally precise, enabling continuous and smooth changes, which provides convenience for comprehensively testing the response of products under different vibration conditions.
