| 中文摘要: |
| 以斜支承包装系统为研究对象，建立了半正弦脉冲激励下系统的无量纲非线性冲击动力学方程，采用数值计算方法分析了系统加速度响应及冲击谱，探讨了无量纲脉冲激励幅值、无量纲脉冲激励时间、系统支承角以及阻尼对系统加速度响应及峰值的影响规律。研究表明：无量纲脉冲激励幅值、无量纲脉冲激励周期、系统支承角及阻尼等对系统响应峰值影响显著。 |
| 英文摘要: |
| Dimensionless nonlinear dynamical equations of packaging system under the action of half-sinusoid pulse were established by using tilted support packaging system as study object. The shock response acceleration of the system and the shock response spectra were studied using numeric method. The effects of peak pulse acceleration, pulse duration, angle of tilted support spring and damping were discussed. It was concluded that the effects of peak pulse acceleration, pulse duration, angle of tilted support spring and damping ratio of the system are particularly noticeable. |
