Abstract: In a piezoelectric vibration type force sensor according to the present invention, vibration is restricted by a friction force between a piezoelectric body and a restricting member, and hence a range of sensing forces can be expanded compared with a case in which the vibration is restricted directly from a direction that is the same as an vibration direction. A conventional structure, in which a lead wire is soldered directly for electrically connecting the piezoelectric body to an external control circuit, causes a restriction of the vibration due to a solder attached to the piezoelectric body, resulting in narrowing the sensing range. Using the piezoelectric vibration type force sensor, the range of sensing forces can be expanded by making a state in which conducting portions of the piezoelectric body and the restricting member are not fixed but contact with each other for keeping electric conductivity.

Abstract: A method for measuring a tangential tightness of a stator coil within an armature slot of a stator assembly in an electric generator. The stator coil is excited to produce a vibratory response therein. The vibratory response of the stator coil is detected and a frequency response function of the vibratory response is determined. A tangential tightness of the stator coil within the armature slot is estimated based on the frequency response function of the vibratory response of the stator coil.

Abstract: A high frequency flexure-based dynamometer for measuring vibrations to use in determining cutting forces in a tool is disclosed. The dynamometer device may operate within a pre-selected high frequency range while measuring cutting forces less than about 1 N. The dynamometer may include two coupled flexures that interact to produce vibration modes at the edge of a selected bandwidth of interest. These modes may produce a frequency response function within the desired frequency band that has a magnified response and is substantially constant. The dynamometer may include a workpiece mounted to one of the two flexures and a one or more precision accelerometers mounted to the first or second flexures. Finite element analysis may be used to optimize the flexure design.

Abstract: A feedback-controlled force measuring apparatus with a force input element, a piezoelectric force generating element and a precision motion detection element in a feedback-controlled loop. Two embodiments are described. In one the force-generating element is a supported proof mass to sense linear acceleration, and in the other the force-generating element is a diaphragm supported to sense external pressure. The precision motion detection element employs resistance and inductance of a case-fixed coil of wire modulated by the distance from the coil to an electrically-conductive member connected to a force-generating element. The piezoelectric force generating element may be either a bimorph, or a piezoelectric stack.
