Cushion vibration testing: comparing sine Vs. random excitation of different spring-mass models

摘要

Cushion materials are used as mechanical springs in many protective package systems for shock and vibration mitigation. For larger and more fragile products, vibration characteristics of cushions are more importnat than shock characteristics. To design an effective vigration attenuation system, the engineer must know the vibration characteristics of the product and the cushion materials in uestion.
