摘要
爆炸冲击震动下隔震系统的可靠性问题 ,是一个关系到人员安全和仪器设备正常工作的重要问题 ,目前 ,尚未见到这方面的研究成果。本文在一定的简化下建立了线性隔震系统的可靠性分析方法 ,并进行了数值计算。分析表明 ,照搬文献 [2 ]的加速度容许值标准设计的爆炸冲击震动线性隔震系统 ,其可靠性是相当差的。
The reliability of an isolation system is a key problem.It is concerned with the presonal safety and the normal operation of facilities due to an impulsive loading.A simplified method for the reliability of an isolation system under a blast shock and vibration is proposed in the paper.The results show that the reliability of an isolation system designed by the reference[2]is usually poor.We found that the reliability of system is more influenced by the natural frequency.The reliability of system will be increased as the natural frequency decreased.A good way to improve the reliability of system is carefully to select the natural frequency.
