    摘要： An inflatable bladder system for applying generally uniform pressure to parts being welded to insure proper contact at the welding interface includes a first sheet that is generally transparent to electromagnetic radiation to allow such radiation to pass therethrough. This electromagnetic radiation serves to heat the parts to a temperature sufficient to create a weld. The inflatable bladder also includes a second sheet that is also generally transparent to electromagnetic radiation. The second sheet is coupled to the first sheet to create a sealed volume therebetween. Fluid is selectively introduced into the sealed volume in order to expand the bladder into engagement with the parts being welded to exert a generally uniform pressure thereon.

    摘要： A flexural spring support for a vibratory apparatus comprises a substantially stationary first member, a second member disposed opposite and spaced from said first member and intended to undergo translating motion in a plane, and a plurality of elongated flexural springs coupling said members to one another. Each spring is provided at its ends with a respective flange, the underside of which is in forced engagement with the surface of the associated member. Adjustable fastening means cause the engagement pressure to be of such magnitude as to prevent relative motion between the flange and member surface when said first member undergoes motion, thereby substantially eliminating fretting corrosion previously manifest at the springs. In addition, each spring is configured to form a clamped clamped constant strain tapered beam.

    摘要： A filter for absorbing electromagnetic radiation which is used in heating a welding zone wherein a first part is joined to a second part. The filter includes a solid material for absorbing undesired wavelengths of radiation from a heating source before the radiation reaches the welding zone. The filter also has a housing which contains a chamber within which a fluid is placed. The fluid cools the solid material and also may absorb undesired wavelengths of radiation from the heating source before the radiation reaches the welding zone. A heat exchanger is connected to the filter in order to cool the fluid during the filtering process.

    摘要： A force control system for an electromagnetic actuator includes an observer that outputs signals representing the instantaneous position and velocity of a movable member, and a position controller that receives the output of the observer and signals representing a desired position and a desired velocity. The position controller compares the output of the observer with the desired position and velocity signals to generate position and velocity error signals. The position controller further generates force command signals required to position the movable member at the desired position with the desired velocity based on the position and velocity error signals. The position component may be eliminated from the force command signals, resulting in controlling only the velocity of the movable member. In accordance with other aspects of the invention, a force control system for an electromagnetic actuator includes a flux observer that low-pass filters the voltage applied to phase coils to estimate the flux of the phase coil and provide a signal representing the estimated flux at the output.

The system may include a force controller that converts desired force command signals into desired flux command signals and a flux controller that controls the flux in a magnetic core of the stationary assembly to effect the desired movement of the movable member. The stationary assembly may include a plurality of magnetically uncoupled E-cores of paramagnetic material.
