为达到噪声指标,舰船动力装置普遍采用弹性安装,该种方式对横摇工况下动力装置与轴系连接的联轴器补偿量提出了更高的要求。通过建立舰船动力装置-推进轴系全系统有限元模型,提出横摇工况下弹性安装动力装置的联轴器补偿量分析方法,获取不同横摇工况下联轴器补偿量需求,并利用试验台架试验验证了模型的准确性。研究结果表明,联轴器刚度的增大有利于降低摇摆工况下的补偿量要求,但会给邻近的支承轴承增加负荷;在设计弹性安装动力装置-推进系统的联轴器时,应对刚度、补偿量与支承轴承载荷进行协同考虑。研究结果可为低噪声舰船动力装置联轴器设计提供技术支撑。 相似文献

通过非线性有限元分析软件建立了空气弹簧联轴器模型,分别利用Rebar单元和Herrmann单元模拟帘线以及气胎胶囊,从而实现对刚度特性的计算。本文分析比较了影响空气弹簧径向刚度及轴向刚度的多种因素,包括结构形式(如气囊对数、气囊容积、气囊高度、气囊有效直径)、气囊帘线材质、帘线层数、帘线的角度、橡胶的材料特性以及气囊初始充气压力等。通过有限元仿真设计方法,对几种影响空气弹簧刚度特性的因素进行了优化,从而确定空气弹簧联轴器的参数。本文不但得到了各参数影响联轴器刚度的趋势,而且得到了各参数下联轴器的刚度值。 相似文献
