    摘要: A method is disclosed for computing clutch engagement characteristics of a friction clutch system in a vehicle powertrain. A dynamic model of the system is used under conditions that cause clutch slipping. Algebraic equations defining a functional relationship between clutch torque and an engagement angle have characteristic parameters that are estimated using a non-linear least squares technique. The non-linear least squares technique repetitively minimizes the difference between a measured clutch output speed and a clutch output speed from the system dynamic model for the same inputs until a small insignificant error is reached. Parameter estimates are used to update each engagement characteristic.

    摘要: A reconfigurable variable blank-holder force system (and method) for producing sheet metal stampings comprises a portable hydraulic unit, controlled by a digital control system and a knowledge-based expert system to enable reconfigurability and an easy transition from the try-out stage to production. The knowledge-base has a hierarchical structure and includes stored information about part geometry, material properties and press parameters. The expert system enables an operator to determine optimal blank-holder forces, and to fine-tune through a graphical interface unit. The optimal blank-holder forces are generated by hydraulic force actuators, using a controller running a nonlinear algorithm that accounts for valve nonlinearities, variable flow-rate and numbers of operational cylinders. The portable hydraulic unit preferably comprises hydraulic cylinders with quick disconnect hoses, a manifold, servo-valves and a pump unit. A structured method to utilize this system to produce sheet metal stampings is also described. An article embodying the method is included.

    摘要: A method is disclosed for estimating clutch engagement characteristics of a friction clutch system in a vehicle powertrain. A dynamic model of the system is used under conditions that cause clutch slipping. Algebraic equations defining a functional relationship between clutch torque and an engagement angle have characteristic parameters that are estimated using a non-linear least squares technique. A non-linear least squares technique iteratively minimizes the difference between a measured output clutch disk speed and an output clutch disk speed from the system dynamic model for the same inputs until a small insignificant error is reached. Parameter estimates are used to compile an estimated clutch engagement characteristic.

    摘要: The system and method of the present invention enable a task performance system made up from two or more components to be readily modified, in response to one or more predetermined criteria, to adapt to new functional and/or operational requirements. This modification may be automatic manual, or a combination thereof. Likewise, the predetermined criteria may range from failure of one or more task performance system components, to an instruction received from an authorized operator. The inventive system and method accomplish these objectives by causing one or more of the components of the task performance system to change functionality (e.g., to change the functions being performed by one or more components, to add one or more functions to one or more components, etc.) to implement the desired modification of the entire task performance system.

    摘要: A microelectromechanical device wherein the displacement of an electrothermally compliant actuator is perpendicular to a mounting substrate allowing in a first embodiment a fluid control valve to be opened and closed and in a second embodiment a plurality of electrical contacts to be opened and closed. The electrothermally compliant actuator is comprised of a pair of beam structures having a joined thick beam and then beam such that a flow of electrical current causes the beam structures to bend. A flexible isolation layer is used to thermally isolate the electrothermally compliant actuator from the fluid in another valve assembly embodiment.
