摘要
为了提高游艇的舒适性,针对游艇振动问题,以降低振动响应为目标,采用板架动力刚度算法,改进了机舱板架结构,并通过算例仿真验证减振效果.结果显示,改进后游艇各频率激振力的振动响应均有不同程度的降低.该方法可为游艇设计制造者改进机舱板架和控制游艇振动提供参考.
Grillage structure was the key link of vibration transmission, and to improve grillage structure in engine room was an important mean of reducing vibration and improving comfort. This paper used grillage dynamic stiffness algorithm to determine the optimal installation position of transverse cap-type profile and used an example of simulation to verify the effects of reducing vibration. The results showed that the vibration of all frequency was reduced. This method could provide reference for yachts designers and manufacturers to optimize grillage structure in engine room and reduce yachts vibration
