| 以考虑易损件的斜支承包装系统为研究对象，建立了系统无量纲非线性动力学方程，利用龙格-库塔法对易损件振动响应特性进行了数值分析。讨论了系统支承角、系统频率比以及系统质量比等对易损件加速度及位移响应的影响规律。研究结果表明：系统支撑角、系统频率比等对易损件加速度及位移响应影响显著；随系统支承角的减小，易损件加速度及位移响应幅值减小；增加系统频率比可使易损件加速度及位移响应幅值明显降低；低频率比条件下，增大质量比可抑制易损件加速度及位移响应幅值。研究结论可为斜支撑减振系统的设计提供理论依据。 |
| 英文摘要: |
| The nonlinear dimensionless dynamical equations of tilted support packaging system considering vulnerable part were established, and the numerical analysis of vibration response of vulnerable part was carried out using Runge-Kutta method. The effects of the angle of the tilted support, the frequency ratio and mass ratio of the system on the response of acceleration and displacement were discussed. It was shown that the effects of the angle of tilted support and the frequency ratio of the system are particularly noticeable; increasing frequency ratio of the system can obviously decrease the maximum response acceleration and displacement of vulnerable parts; the peak of vibration response of vulnerable parts can decreased at low frequency ratio by increasing mass ratio. The purpose was to provide academic foundation for design of shock absorber with tilted support. |
