Abstract:
Three designs for reducing the vertical oscillations induced in equipment mounted on the wings of AH-1G helicopters are submitted. A design for a variable stiffness spring to accommodate a change in the mass of the system to be isolated is presented. By use of an analog simulation of a dynamic absorber it is shown that a dynamic absorber is not satisfactory for small ratios of damper mass to system mass. An experimental program is formulated to determine the dynamic properties of a test fixture to be used in determining isolator effectiveness. Author
