Abstract:
The study was conducted to determine the dynamic characteristics of non-isolated avionics equipment mounts and the effect of the characteristics on the equipment the mount supports. The response to both sinusoidal and random acceleration inputs was investigated. Lumped mass models were postulated to describe the mount response to sinusoidal inputs. These models reduced the mount characteristics to a single parameter, the stiffness. Experimental investigation showed a wide range of stiffnesses for existing mounts in service so these models were considered unsatisfactory. A linear system model was postulated to describe the mount response to random input. Experimental investigation showed that non-isolated mounts have magnification factors near unity on an average basis but that individual points may have significantly higher g levels.
