In order to make vibration analysis an easy and automated task for designers, it is desirable to develop interactive vibration analysis systems using personal computers or engineering work stations which have a user-friendly interface for easy input of the vibration model, and which can perform automatic generation of equations of motion, and automatic numerical analysis of them. As the first step towards such systems, an automatic generation system of equations of motion was developed for two-dimensional vibrations of multi-body systems. The system developed is written in Smalltalk-80 which is a typical object-oriented language, and can perform the following : (1) The system has user-friendly interface for graphic input of vibration model which enables users to make figures of a vibration model on the display by choosing the vibration model elements listed in the menu by a pointing device (mouse). (2) The system is applicable to extensive models of two-dimensional vibrations of multi-body systems which contain various constraints and nonlinear elements.
