Harmonic excitation of a SDOF
Harmonic excitation of a SDOF
Summary
阻尼单学位的精确解Of Freedom (SDOF) system is excited by a harmonic force is calculated [1]. It is compared to the numerical solution provided by the Matlab built-in function ode 45, the central difference method, Newmark method and the 4th order Runge-Kutta method, the implementation of which is based on the book from S. Rao [2].
