| 中文摘要: |
| 以悬挂式弹簧缓冲包装系统为研究对象，建立了矩形脉冲激励下系统几何非线性无量纲动力学方程，得到了系统的最大冲击响应谱。讨论了无量纲脉冲激励幅值、悬挂角度以及系统阻尼等对冲击谱的影响规律。研究表明，无量纲脉冲激励幅值、悬挂角度、系统阻尼等对系统冲击响应峰值影响显著，增加系统阻尼可有效降低系统加速度响应峰值。研究结论可为悬挂式弹簧缓冲系统的设计提供理论依据。 |
| 英文摘要: |
| The geometric nonlinear dimensionless dynamical equations of suspension spring system were developed and the maximum shock response spectra were obtained under the action of rectangular pulse. The effects of the dimensionless peak pulse acceleration and damping ratio on the shock spectra were discussed. The results showed that the effects of dimensionless pulse peak, the angle of suspension spring and the damping ratio of the system are particularly noticeable; the damping can obviously decrease the maximum shock response acceleration of the system. The purpose was to provide reference for design of shock absorber with suspension spring system. |
