Damage Evaluation of Hyperbolic Tangent Packaging System with Critical Component
The shock characteristics of hyperbolic tangent packaging system with critical component under the actionof half-sine acceleration pulse were investigated. The dynamical model of the system was developed, and thenumerical results of the dynamical equations were obtained. Then, to evaluate the damage potential of shock tocritical component, a new concept of damage boundary surface was proposed, with the critical velocity line, thecritical acceleration line and the frequency ratio of critical component to main body as the three basic coordinateparameters. Based on the results, the effect of the frequency ratio, the fragility in addition to the damping ratio ondamage boundary of critical component was discussed. Its shown that all of their effects are noticeable. Thestrong frequency ratio dependence nature of the effect was found. By increasing the defined system parameter, thesafe region of critical component can be broadened. Moreover, the damage boundary of critical component can effectivelycontrolled by altering the damping ratio of the critical component and cushioning pad. The results lead tosome insights into the design of cushioning packaging.
