Component Qualification Using 3D Laser Vibrometry and Transmissibility Models
This paper details the application of 3D laser vibrometry in the qualification of a lightweight cable structure for operational usage under a number of vibration environments. The paper describes how transmissibility models were developed, based on laser vibrometry, and applied to numerous vibration environment specifications in order to reduce the number of ground-based testing sequences required. The paper also describes how a spatially dense measurement model removed the requirement to develop a detailed finite element model and the associated expensive material dataset.
