| Abstract: |
| The frequency reliability analysis method of avoiding resonance is proposed when the vibration problems of the random dynamic structural systems are studied.Furthermore,the formula of frequency reliability sensitivity is obtained,which provides a preliminary efficient way to analyze how each random parameter contribute to the system reliability.Combining frequency reliability and sensitivity theory with optimization design method,the frequency reliability-based robust design method is proposed.Moreover a numerical example is provided,the frequency reliability-based robust numerical results are obtained,which are in agreement with practice and demonstrate the effectiveness and accuracy of the proposed method,which can provide the reasonable and necessary basis for the design,manufacturing,application and evaluation of the random dynamic structural systems. |
