Vibration testing has its roots dating back around 40 to 50 years. Initially, the concept wasn't widely recognized or appreciated for its significance. It wasn't until World War II that the importance of vibration testing became evident. Many aircraft, ships, vehicles, and equipment experienced failures during use, with a significant percentage of components failing due to unexpected vibrations. Research later revealed that most components couldn’t endure long-term resonance from their own structure or from vibrations during transportation, leading to loosening, cracking, and mechanical failure. These issues caused not only zero-loss situations but also substantial financial losses. Once these findings were made public, vibration testing—specifically through vibration test benches—gained widespread attention, prompting heavy investments in research and development.
With the establishment of modern vibration measurement and analysis theories, the methods and logic behind vibration testing have continuously evolved. Today, with the frequent movement of goods across global supply chains, vibration testing has become even more critical. The primary goal of a vibration test bench is to simulate controlled vibrations during testing, ensuring that products can withstand real-world transportation or environmental vibrations throughout their lifecycle. This process also helps validate product design and functionality. According to statistics, a 3% improvement in design quality can lead to a 20% increase in recycling rates and a reduction of 18% in unnecessary costs. Vibration simulations come in various forms, such as resonance search, resonance dwell, cycle scan, random vibration, and stress screening, each tailored to specific testing needs.
