Sommario
Usando il principio delle potenze virtuali si sviluppano equazioni nonlineari di moto per sistemi arbitrari di corpi rigidi interconnessi con giunti cinematici, molle, ammortizzatori ed elementi che esercitano forze attive. Un parametro essenziale del sistema è la cosiddetta matrice del cammino che descrive la topologia del sistema. Un programma di calcolo genera le equazioni in forma simbolica per successive simulazioni numeriche del comportamento del sistema dinamico. Il programma trova applicazioni sia in vari settori dell'industria sia nella ricerca scientifica.
Summary
Using the principle of virtual power nonlinear equations of motion are developed for arbitrary systems of rigid bodies interconnected by kinematical joints, springs, dampers and active force elements. An essential system parameter is the so-called path matrix which describes the system topology. A computer program generates the equations in symbolical form for subsequent numerical simulations of dynamical system behaviour. The program finds applications in various branches of industry as well as in scientific research.
