Vibration testing has an important role during vehicle development allowing test engineers to characterize the effect of long-term, road-induced vibration and shock on the performance and service life of automotive systems and vehicle/engine components. NVH Engineers use vibration testing specifications such as MIL-STD, ASTM and many more in order to improve quality and safety.
Packaging vibration testing develops protocols and design standards that define how packages should perform to ensure protection of their contents during the ever changing risks of the global distribution environment. Such industry standards would be ISTA and ASTM specifications.
Vibration testing is critical and almost always demanded on military hardware supplied to defense contractors and government entities ensuring the durability of components, electronics and assemblies. Qualification Tests, Environmental Stress Screening (ESS), or test specifications such as MIL-STD 810, MIL-STD 516 or similar may all be part of the test process.
Electronic vibration testing encompasses a wide variety of products that are used in daily life. Weeding out design failures, shipping/handling flaws and assembly errors before entering the marketplace for cell phone, personal computer or even radio manufacturers is a must to ensure device longevity.
Vibration Research works closely with the vibration education departments at universities and colleges around the world providing our very best offerings to the students and faculty in order to produce competent and capable engineers for the work force. License keys that allow for multiple users and multiple software modules are essential in an educational setting. Applications vary all over in an educational setting. Some examples are modal testing, data acquisition, introduction to the vibration, sine sweep, random testing and shock testing among other applications.
Commercial testing laboratories provide capital facilities and in-depth testing expertise to industry. They see a broad range of applications such as MIL-STD, Modal Testing, HALT/HASS, Data Acquisition, Vibration Testing, Seismic and Drop Shock testing among various other applications. Most test labs have a wide enough range of shaker applications to fit any applications.
When testing critical, high-value products it’s essential to understand the extent of random vibration conditions and product responses during start-up. This is especially important on short duration tests, as hidden test conditions would lead to product designs based on under or over-testing. Using Vibration Research’s iDOF development of space vehicles, satellites and aircraft will have the smoothest control lines in the industry. Aerospace applications include military standards such as MIL-STD 810 and DO-160.
In the medical industry, the use of vibration testing is critical since hidden damage from vibration can have significant side affects. Vibration affects individual components in a product, the product itself, the product with packaging and packages stacked together. Some common test standards for production testing are ASTM D999 and D3580.
Consumer Goods is an especially competitive market so vibration testing is critical to your company’s integrity, device reliability and robustness, along with product life cycle. Some tests include environmental conditioning (HALT/HASS), package validation and accelerated fatigue testing. Using these vibration tests we can determine weaknesses and failure conditions before becoming a warranty issue or a critical safety risk.
