摘要: An active force actuated vibration isolation system uses a velocity sensor in the form of a velocity-sensitive geophone to sense payload velocity and modifies the geophone signal to control the force applied to oppose the vibration. The modified signal effectively reduces the inherent resonant frequency of the geophone and avoids instability.

摘要: An inertia force generating device comprises two pairs of coaxial counterrotating eccentric rotors, whose rotational speeds and relative positons are automatically and continuously controlled so as to cancel undesirable vibrations produced by another device. Within each rotor pair, the two rotors have an adjustable angle between their mass centers, so that the effective eccentricity of the pair can be varied, and the phase between the two pairs can also be changed, to alter the direction of the maximum or minimum inertial forces developed. The four rotors include shells of different diameter, nested together on a center plane of the device, or parallel plates configured to maintain a minimum spread of mass centers along the rotational axis.

摘要: An active vibration isolation system employing an electro-rheological fluid comprises a damper having a servovalve fluidically coupling a load supporting actuator to an accumulator. The servovalve includes an orificed plate arrangement, across which a voltage potential is impressed in accordance with a command signal derived from response sensors. The viscosity of an electro-rheological fluid contained within the servovalve reacts to the voltage potential so as to regulate the fluid flow. In this manner the damping coefficient is modulated to as to approximate a "sky-hook" damper.

摘要: An overload protection device adapted to be secured between a robot arm and a tool, comprises a floating piston (20) within a cylinder (18). Hall effect sensors (124) are spaced around the cylinder wall and mating magnets (40) are spaced around the piston wall. The cylinder is pressurized to axially align the piston with the cylinder and to position each magnet in alignment with a sensor. When an overload occurs involving either the robot arm or the tool, the magnets are moved relative to the sensors causing the sensors to signal for depressurization of the cylinder. An electronic system (FIG. 27) responsive to the Hall effect sensor signals lights an "overload" LED D1 and triggers a timer circuit T1 which generates a timing pulse of fixed duration. During the duration of the timing pulse, the robot is de-energized. A red LED R is illuminated indicating the robot system is not ready to be operated. Also, a solenoid valve L1 is energized, cutting off the pressure to the cylinder.

摘要: A flexible fluid conductive coupling for use with fluid flow systems has short fluid conductive cylindrical sections having different diameters so chosen that the smaller diameter section may fit within, and well clear of, the larger. A pair of external mating flanges are provided at the end and near the end, respectively, of the larger and the smaller cylindrical section, and a combination coupling and seal laminated from alternating layers of resilient and rigid materials is held in compression between these two flanges. The facing surfaces of the flanges are shaped to provide for the desired motion or displacement. The slight extension of the smaller cylindrical section into the larger provides a stagnation region between the two cylindrical sections, thereby protecting the seal from abrasive injury which might be caused by particulate matter in the fluid stream.

摘要: A frusto-conical laminated elastomeric bearing is provided wherein at least some of the layers are graded in composition so that they have a first relatively high modulus of elasticity at the inner circumstance, a second lower but still relatively high modulus of elasticity at the outer circumference, and a third still lower modulus of elasticity in an intermediate position between the inner and outer circumferences, with the grading being arranged so as to provide an optimum balance of strain distribution and spring rates consistent with bearing lifetime and reduced-torque considerations.
