船舶轴系高静低动扭振隔振装置结构设计及分析
图 4所示为负刚度弹簧连杆机构在静平衡位置和受外力作用下发生扭转的示意图。记在静平衡位置时弹簧和连杆的总长度为a,弹簧原长为LSO ,弹簧刚度为KS ,弹簧的压缩量为δ,连杆长度为b。在外力FW的作用下,连杆发生偏转后(图中虚线所示),将与原静平衡位置形成夹角φ。
式中:ωn为隔振系统固有圆频率;ξ为隔振系统阻尼比;Ω为隔振系统激励圆频率与固有圆频率之比,也即频率比;τ为与隔振系统激励时间相关的无量纲。这样,系统的运动方程无量纲化后的表达式为
式中:J为隔振系统的转动惯量;C为隔振系统的阻尼; M为隔振系统的弹性恢复力矩; Me为隔振系统所受到的外力矩; ω为外力矩的激励圆频率。引入如下无量纲变量:
当隔振系统处于静平衡时,从系统输入端施加一个幅值为 的余弦激励,则系统的运动方程为
因为弹性力矩与阻尼力矩相差传递扭矩Mˆ的幅值等于弹性力矩与阻尼力矩的t平方根:
由此,可得隔振系统传递给轴系从动轴的扭矩Mˆ 表达式为
步整理,可得幅频响应方程为
为一阶刚度系数;
式中:
则高静低动扭振隔振系统的扭矩传递率 可以写成分贝的形式:
且能承载约提扭振隔振装置具备高静低动特性。
