碩士 === 國立高雄科技大學 === 輪機工程系 === 107 === In this paper, a method for studying the vibration transmissibility of the isolator was presented. The method was based on a mathematical model of a two-degree-of-freedom spring-damping-mass system, Based on Lagranges equation, the equations of motion of the above-mentioned two-degree-of-freedom system were derived. By Laplaces operation, the mathematical expressions of the vibration isolation transmissibility can be obtained. Finally, the influence of some parameters (such as damping coefficient, spring constant, mass) on the vibration transmissibility of the isolator was discussed by MATLAB program in this paper. The method proposed in this paper is helpful to the vibration isolation design of the system and has practical application value.
