Validate FEA results & prove product durability
By condensing a lifetime of stress and wear into a short period of time, noise and vibration testing can reveal hidden design weaknesses. Moreover, beyond merely withstanding short-term physical forces, developers need to ensure that their products will maintain the integrity and quality that represents the brand in the longer term.
Although product qualification and verification are done through extensive simulation in the development phases through simulation, it is also necessary to do physical testing on prototypes and end-of-line items. This both validates simulated results provided by vibration measurement and analysis to prove product durability to customers.
