泡沫铝冲击吸能器被动冲击隔离技术研究

对隔振系统中引入泡沫铝冲击吸能器进行探讨.首先,在综合考虑最大加速度和最大相对位移这2个影响舰船设备防护的重要指标情况下,对舰船单层隔振系统中引入泡沫铝冲击吸能器进行了理论分析,在此基础上进行了实验验证.通过实验结果可知,泡沫铝冲击吸能器能有效消除舰船设备的二次冲击.实验结果与理论结果吻合较好,可为泡沫铝冲击吸能器的应...

Passive-shock-isolation technologies based on Al foam energy absorbers

An Al foam energy absorber was introduced to a vibration isolating system to replace the traditional rigid and elastic buffers.And the corresponding theoretical analysis was carried out by comprehensively considering the two important indexes:the maximum acceleration and the maximum relative displacement.Based on the theoretical analysis,the validation experiments were conducted.The experimental results show that the Al foam energy absorber can effectively prevent the warship’s equipments from the secondary impact.Good agreement between the experimental and theoretical results displays that this investigation is helpful for the application of the Al foam energy absorbers in engineering.
