Introduction 1．Determine Product Fragility Determine the amount of mechanical shock the product can survive on its own by evaluating “fragility” or “g-factor ”. 2. Determine Conditions Consider the handling and transportation environment the product will face and establish the amount of shock the product may encounter (“drop height”). 3. Calculate Cushion Requirements Use dynamic cushioning curves to determine thickness, static loading and bearing area.Introduction 1．Determine Product Fragility Determine the amount of mechanical shock the product can survive on its own by evaluating “fragility” or “g-factor ”. 2.
