摘要
首先模拟原型观测两端弹簧刚度,用20节点等参元求解固定导叶在空气中的自振特性;进而推导了固定导叶的水体附加质量,并计算其在水中的自振特性。
First, simulating spring stiffness at two ends of stay vane based on field test results,using 20 nodes isoparametric element method the characteristics of free vibration of stay vane in the air can be determended, and then studing the adding mass by water on stay vane the characteristics of free vibration of stay vane in the Water may be determended too.
