| Summary: | An electromagnetic vibration sensor should be very sensitive in order to detect a ground vibration and could damp as close as to critical damping to differentiate between two consecutive vibrations. In this thesis 1 firstly investigate about the vibration theory of electromagnetic vibration sensor and study about its sensitivity parameter, I also design a damping system for viscous damping by using a bigger area of plate oscillates in high viscosity of liquid which is glycerine and assemble the damping system with serial spring arrangement to increase its sensitivity. I learnt that, the designing of the damping system and the spring arrangement would lead to a high sensitivity of a seismometer. |
