✦ Synopsis

This work presents a software development and implementation on the frequency and response studies of vibratory systems, The systems can either be a discrete or continuous model, which can be represented by a set of coupled second-order differential equations. Several commonly-used numerical methods are used in the response analysis for user's choices such as central difference, fourth-order Runge-Kutta, etc. The system frequencies are obtained by using a fast Fourier transform (FFT) method, giving data generated in the response analysis. Two types of the windows are used in the FFT analysis: rectangular and Hanning windows. The software implementation enables one to effectively analyze vibration problems on a screen environment. Examples of a discrete model and a continuous system are considered to illustrate the performance of the software. The results of response and frequencies are discussed and commented.
