Paper Title:
Evaluation of Dynamic Property of Radiogram under Repetitive Drop Shock
  Abstract

Repetitive impact during highway and railway transportation has potential and severe harm for the product with fragile or damageable component. The radiogram belongs to a typical electronic product with panel and box structure, and occurs with the falling down of loudspeaker contacted on the top box, the failure of electronic components, and the fracture of outside box during transportation and storage. So the main feature of this article is the analysis on the natural vibration property, and the evaluation on the drop shock property including amplification factor and relevant curves under nine kinds of repetitive impact with different impact duration and drop height. The results show that the amplification factor markedly rise while the impact duration 2.02ms (nearly causing the resonance of radiogram), the repetitive drop shock may bring more serious damage than single impact load, so the case should be paid attention for the design of package cushioning.
