Abstract
APPLICATION OF MULTI-TERMINAL NETWORK THEORY TO VIBRATION PROBLEMS REQUIRES KNOWLEDGE OF THE POINT AND POINT-TO-POINT MECHANICAL ADMITTANCE MATRICES AT THE MECHANICAL TERMINALS OF THE STRUCTURES TO BE CONNECTED TOGETHER. THE ADMITTANCE MATRICES CONTAIN ELEMENTS RELATING LINEAL MOTIONS AND FORCES(LINEAL ADMITTANCES), LINEAL MOTIONS AND MOMENTS (LINEAL/ ROTATIONAL ADMITTANCES), ROTATIONAL MOTIONS AND FORCES (ROTATIONAL/LINEAL ADMITTANCES), ROTATIONAL MOTIONS AND MOMENTS (ROTATIONAL ADMITTANCES). CURRENTLY COMMERCIAL APPARATUS IS AVAILABLE FOR MEASURING ONLY LINEAL ADMITTANCE.THE WORK PROPOSED UNDER THIS PROJECT, IF SUCCESSFUL, WILL PROVIDE TRANSDUCERS AND ASSOCIATED ELECTRONIC EQUIPMENT FOR OBTAINING ALL OF THE ELEMENTS OF THE ADMITTANCE MATRICES.
