Modelling

Abstract

In investigations of the dynamics of structures and mechanisms, use is made of “dynamic models” which include a mathematical description of the dynamic properties of the system. Although the description imposes no limit on the degree of detail, its mathematical treatment may lead to considerable difficulty. The dynamic model should therefore be presented in such a way that, on the one hand, practical mathematical treatment is possible, while on the other the accuracy with respect to the actual behaviour is sufficient. The most important property of the dynamic model is, however, that it can be used in the practice of machine design.
