The main objective of the present work is that to construct a combined Pendulum Type Mass Damper (PTMD) in a structure to demonstrate the effect of damping of vibrations. In order to achieve this, a simple prototype has been developed. An inductive proximity sensor has been used to measure the vibrations of prototype with the PTMD system in terms of the induced voltage signal. The induced voltage signals have been acquired by using an Arduino UNO controller board. The experiments have been carried out to measure the amplitude of displacement of the vibrations in the structure in terms of voltage signals for two cases: (i) Without adding the damper or tuned mass and (ii) With adding the damper or tuned mass of 100 g, 150 g, 200 g, 250 g and 300 g respectively. However, this work reports the experimental results only for 250 g. The theoretical analysis of PTMD has been studied and presented in this paper. A numerical model for the combined pendulum type mass damper with the structure has been developed by using MATLAB SIMULINK. A series of simulations have been carried out for the various values the mass ratio, μ = 0, 0.25, 0.5, 0.75 and 1 to show the effect damper or tuned mass on the vibrations of the structure. The simulation results of amplitude of displacement of the structure have been analyzed and presented in both time domain and frequency domain. By keeping the same condition of experimental analysis of 250 g damper or tuned mass, the simulations have been carried out for two cases: (i) Without absorber mass (mass ratio, μ=0) and (ii) With a damper mass of 250 g (mass ratio, μ=0.33) in order to validate the experimental results.
