다점 단순지지된 연속원통셸의 진동특성에 대한 실험적 고찰
An Experimental Study on the Vibraton Characteristics of a Continuous Circular Cylindrical Shell with the Multi-simple Support
초록
This paper presents the vibration characteristics of a continuous circular cylindrical shell multi-simply supported at arbitrary axial positions for searching design parameters. In this modal test the impulse test method is applied to the excitation of experimental model. Natural frequencies are obtained from the peak points of frequency response function(FRF) through frequency analyzer and vibration behaviors are investigated. FE analysis is performed with ANSYS 5.5 to improve the reliability of experimental results. Their results are compared with experimental results. The effect of dynamic characteristics is analyzed for the number of support point on the shell.
