Paper Abstract

Holometric testing of vehicle components to improve their structural characteristics is now a proven methodology. The inherent advantages of a full-field, high sensitivity measurement capability are emphasized for the iterative improvement of prototype structures (static and dynamic) and the timely application to understanding structure related concerns on vehicles in production. Successful acquisition of usable and valid test results requires considerable thought and effort to create a test set-up that recreates as closely as possible the test subject boundary and loading or excitation conditions existing in-vehicle. The recent addition of advanced Computer Aided Holometry (CAH) has significantly enhanced the understanding and utilization of holometric testing by Ford engineering. Recent examples of studies that address both the static and dynamic behavior of components are presented. Continuous wave and pulsed laser holometric techniques have been applied to study the following subjects: (1) self generated brake noise, (2) engine block noise radiation, (3) steering column vibration, (4) engine structure deformation under fastener torque loads and (5) cylinder head deformation under simulated combustion chamber pressure loads.
