The theoretical mechanism employs a nonlinear spring and a cantilever beam. This system has only one fixed support for the spring, and one non-contacted support to prevent the impact of friction in operation for cantilever beam. Exciting forces apply to the structure, including vertical and horizontal forces, and a moment. The cantilever beam is symbolized as an Euler–Bernoulli beam which has nonlinear property. After formulating, detections along the 2D coordinate are pointed out by using a nonlinear approximate method as Adomian decomposition method. The results of this method are compared with the numerical method. It is shown that the values of analysis and the numerical simulation are consistent with small errors. In addition, vibrations of the tip mass which is attached at the end of the beam are derived and simulated. The results of the tip mass vibrations are harmonic responses which prove that vibrations of any system always remain under harmonic conditions. This finding and the mentioned results are the base for the development of the new mechanism for both sensors and energy-harvesting devices. |
