Modern computers provide the number crunching capability necessary to solve the complex fatigue evaluation, CirVibe provides the model development and methods. Testing remains an important part of understanding product life, but CirVibe makes the product development process efficient.
CirVibe methods provide product understanding during demanding product development schedules. CirVibe's highly automated pre- and post- processors eliminate the need for a user to be a FEA specialist, yet FEA specialists can use CirVibe for time saving advantages. Time is spent evaluating and applying results, rather than spent with input detail and error chasing. The ease of analysis permits evaluation of parameters, support modes, and component position for developing optimum screens or for obtaining maximum life when used during the design process. Since actual test data can be entered into CirVibe, fatigue damage differences due to changes in frequency or transmissibility response of test units can be easily evaluated. By concentrating on the results, the user can gain an understanding of life-usage and draw on experience to optimize environmental stress screens or optimize design capabilities. The ability to rapidly analyze variations in support conditions and vibration requirements make CirVibe an ideal tool for evaluation of Commercial Off The Shelf , COTS hardware.
to End User of CirVibe:
Value of CirVibe for COTS - Vibration
All electronic systems experience shock and vibration - loading that occurs when transported by ground, air, sea or rocket. Often an equivalent life vibration requirement (Accelerated life test) is established for testing equipment to verify its capability to survive the loads experienced over a life of service in the field.
All involved in the COTS final usage (the designer, producer, system developer and end user) should be confident of the capability of the hardware to meet the design goals. Often hardware is qualified for use with a single qualification test and application of a simple empirical formula for life verification. One test is not much assurance that all similar products can meet the requirements. Electronic systems have potential for large variations in geometric features and material properties that can have substantial effects on vibration life capability.
Expensive testing programs can be used to cover uncertainty associated with changing requirements (upscreening), or allowance for parameter variations.
CirVibe tools make the testing process effective and cost efficient. With CirVibe tools, rapid analysis of variations in geometries, properties, vibration spectrums and support conditions is possible. Results are shown in life usage on a component level basis, providing product understanding never before available at this level of effort.
Through experience in test programs supported by CirVibe analysis, all involved in COTS can have understanding and confidence in the vibration life capabilities.
