The problem of the planning of the experiment devoted to definition of the heat drifting of the angular velocity sensor is considered. The methodology for experiment program construction is proposed, with providing a number of general and specific requirements. The methodology is based on the modeling of the simplified dynamic process that describes varying internal device temperature depending on the value of the external temperature. Experimental results confirm efficiency of the developed methodology.

A low-drag, low-power magnetic bearing and a permanent magnet brushless d-c motor-generator have been developed for a satellite flywheel. These will be combined with a terrestrial flywheel and control electronics to make up a flywheel energy storage and conversion system for use in a stand-alone solar photovoltaic residence. Technical and economic performance analyses indicate that, contrary to general thought, a flywheel system will be competitive if not superior to more conventional systems utilizing either present-day or advanced batteries. This derives from the ability of the flywheel to perform the functions of d-c to a-c inversion and optimal impedance matching between the PV arrays and the load in addition to providing energy storage. The motor-generator design will also be discussed. This paper describes the structural topology, performance data, design parameters, and test measurements of the magnetic bearing and motor-generator as well as a description of the flywheel and control electronics to be used. A preliminary discussion of the economic aspects is also included.

Ferroelectric ceramic thin films fit naturally into the burgeoning field of microelectromechanical systems (MEMS). Microelectromechanical systems combine traditional Si integrated-circuit (IC) electronics with micromechanical sensing and actuating components. The term MEMS has become synonymous with many types of microfabricated devices such as accelerometers, infrared detectors, flow meters, pumps, motors, and mechanical components. These devices have lateral dimensions in the range of 10 μm–10 mm. The ultimate goal of MEMS is a self-contained system of interrelated sensing and actuating devices together with signal processing and control electronics on a common substrate, most often Si. Since fabrication involves methods common to the IC industry, MEMS can be mass-produced. Commercial applications for MEMS already span biomedical (e.g., blood-pressure sensors), manufacturing (e.g., microflow controllers), information processing (e.g., displays), and automotive (e.g., accelerometers) industries. More applications are projected in consumer electronics, manufacturing control, communications, and aerospace. Materials for MEMS include traditional microelectronic materials (e.g., Si, SiO2, Si3N4, polyimide, Pt, Al) as well as nontraditional ones (e.g., ferroelectric ceramics, shapememory alloys, chemical-sensing materials). The superior piezoelectric and pyroelectric properties of ferroelectric ceramics make them ideal materials for microactuators and microsensors.

To assess the influence of training on the maintenance of equilibrium on a tilting platform, 13 young healthy male athletes aged 19 to 33 years were randomly divided into experimental ( n = 7) and control ( n = 6) groups. Two experimental sessions were performed before and after a specific 4-wk. training by the experimental group. Subjects stood upright on a tilting platform. The athletes were asked to maintain the platform as horizontal as possible during a 30-sec. test. The three-dimensional movements of the platform versus the ground were recorded by using a computerized optoelectronic digitiser. The platform plane was calculated and its directrix computed. The area of oscillation and instantaneous angular velocity of the directrix at standardized height were calculated. In both groups the area of oscillation and the angular velocity were reduced in Session 2, but the reduction was significant only in the experimental group. Specific training can significantly improve skill at maintaining equilibrium in young healthy sport performers.

Fully Coupled

The objective of this study is to demonstrate the feasibility that a fully-coupled nonlinear piezo(electric)-thermoelastic/control structronic systems can be represented by a single micro-electronic chip. This non-volatile chip is a poTable.lle miniature hardware that serves as a design standard for future calibration and diagnosis of the original “large-scale” structronic system and it can be used anywhere after any catastrophic disruption in extreme hostile environments. Distributed control of a nonlinear structronic beam system (i.e., an elastic beam laminated with distributed sensors/actuators and coupled with control electronics) subjected to mechanical and temperature excitations has been investigated recently. This study is to design an integrated electronic circuit chip encompassing the complete piezothermoelastic and control behavior of the nonlinear structronic beam system. The fully coupled nonlinear beam equations are first discretized into a number of “elements” and each element can be implemented by an active circuit block including operational amplifiers, resistors, capacitors, and other nonlinear multipliers. Signals from the integrated circuit chip of the coupled nonlinear piezothermoelastic beam system are favorably compared with analytical solutions.
