Response of pneumatic isolator to standard pulse shapes
Abstract
Operation of a symmetric passive pneumatic shock isolator is analyzed. The equations are put in dimensionless form and solved numerically. Dimensionless parameters representing mass, stiffness and orifice/piston area ratio were studied. It is found that on the basis of a sustained acceleration input the system has optimum response for a certain range of the area ratio. System response is determined for six pulse shapes: rectangular, half sine, versed sine, rising saw tooth, falling saw tooth and triangle.
