In order to study on nonlinear vibration of current-carrying conductor, a differential equation is established by means of dynamics theory. Based on the method of multiple scales, the first approximate solution and corresponding solution of the primary parametric resonance is obtained. Numerical analysis results show that the amplitude and the topological structure changed with the increase of direct...
According to the nonlinear dynamics equation of the functionally graded material rectangular plate, the nonlinear vibration equation of ceramic and metal functionally graded material rectangular plate subjected to mechanical force excitation is obtained in order to study primary resonance of ceramic and metal functionally graded material rectangular plate subjected to mechanical force excitation....
