Design of a multi-body dynamics analysis program using the object-oriented concept

摘要

A multi-body dynamics analysis program is presented using one of the most useful programming methodologies, the object-oriented concept. The object-oriented concept defines a problem from the physical world as an abstract object. The object becomes encapsulated with the data and method. Simulation is performed using the object's interface. It is then possible for the user and the developer to modify and upgrade the program without having particular knowledge of the analysis program. The method presented in this thesis has several advantages. Since the mechanical components of the multi-body system converts independent modeling into a class, the modification, exchange, distribution and reuse of classes are increased. It becomes easier to employ a new analysis method and interface with other S/W and H/W systems. Information can be communicated to each object through messaging. This makes the modeling of new classes easier using inheritance. When developing a S/W for the computer simulation of a physical system, it is reasonable to use object-oriented modeling.
