Abstract
A skewed, multi-axis vibration fixture supports a device as it undergoes vibration testing simultaneously along three mutually orthogonal axes. A base surface of the fixture is juxtaposed with and coupled to a vibrating surface which shakes along a pre-established vibration axis. A device mounting surface is rigidly coupled to the base surface in a pre-established fixed, skewed angular relationship. The device mounting surface receives and rigidly secures a device as it undergoes vibration testing. The device mounting surface secures the device at an invariable, skewed angle with respect to the vibration axis. Consequently, uniaxial shaking of the vibrating surface is coupled through the fixture to the device mounting surface and is decomposed into shaking along each of the device's three mutually orthogonal axes. The invariable, skewed angular relationship between the device and the vibration axis establishes fixed, pre-established ratios between the shaking along pairs of the device's mutually orthogonal axes. The planar device mounting surface is preferably formed as small as possible to match the shape of the device being tested. A light, rigid vibration fixture permits obtaini…
