ABSTRACT:
A method and apparatus for mounting a video type display tube (20) in a given dynamic mechanical environment employs a plurality of mounting members (56, 56a, 56b, 56c) which are secured to the periphery of the tube (20) at four corresponding predetermined static and dynamic reaction points (1,2,3,4) where substantially minimum bending and torsional stresses occur for the mounted tube (20). Elastomeric grommets (53,54,52a,54a,52b,54b,52c,54c) having a predetermined dynamic stiffness over a desired temperature range capable of attenuating the associated dynamic G forces of the dynamic mechanical vibration and dynamic mechanical shock in the given dynamic mechanical environment are mounted in opposing pairs in an aperture (60) in each of the respective bracket members (56, 56a,56b,56c). A fastener (40,42,44,46) is threaded through each of the mounted grommet pairs (52-54, 52a-54a, 52b-54b, 52c-54c) at the four static and dynamic reaction points and secured to the chassis (22) through respective apertures 24,26,28,30) therein, with the static and dynamic reaction points (1,2,3,4) forming the four mounting points for the tube (20) while substantially minimizing the bending and torsional forces on the tube (20) and the dynamic effects of the G forces on the tube (20).
