Dynamic Seal Design and Experiments of Exciter
摘要
Abstract
The design and experimental research of dynamic seal of exciter was carried out in order to solve the problem that conventional exciter in lab can't be applied underwater directly, satisfying the need of wide band, sta- ble exciting for underwater structure in engineering. Principles and vibration characteristics of electro-dynamic ex- citer were described by simplified model, and dynamic seal was designed in reference of J-shaped slip-ring com- bined seal of Che's seal series, the effects of seal friction on the vibration characteristics were analyzed and verified experimentally. The results showed that the exciter can be applied to underwater single-frequency, narrowband, broadband excitation after dynamic seal design.关键词
