Cushion engineering , design AND testing PREPARED BY HERBERT H. SCHUENEMAN, CP-P/MH PRESENTED BY Westpak , INC. 83 Great Oaks Blvd., San Jose, CA 95119 (408) 224-1300 FAX (408) 224-5113 I. INTRODUCTION A Cushion or " Cushion system" is a protective medium that provides an interface between a fragile product and a potentially harmful environment. Primary "harmful" inputs to be considered here are shock and vibration. To protect a product from shock or impact, a Cushion will "translate" the high peak short duration shock signature that occurs when two rigid surfaces meet (such as a package dropping on a floor) into a low peak long duration shock pulse where the transmitted deceleration level is below the fragility level of the product (see Figure 1).
