Equation 13.11 may also be rearranged to produce an equivalent expression: 13.18 13.19 giving us an expression for the maximum dynamic compression as a function of the maximum acceleration and the drop height. Conclusions: 1. is related to the drop height, the springiness of the cushion and the weight of the product. 2. The stiffer the spring or cushion, the larger the value for. 3. The higher the drop height, the larger the value for(). 4. The heavier the product, the smaller the value of as long as the spring or cushion is working. 2 2 2 2 m d W h k = m m G h W k h h k h W d h 2 2 2 2 2 2 2 2 2 = = =Equation 13.11 may also be rearranged to produce an equivalent expression: 13.18 13.19 giving us an expression for the maximum dynamic compression as a function of the maximum acceleration and the drop height.
