摘要： PURPOSE:To reduce vibration of a Stirling engine and to accomplish silent operation by detecting the inertia unbalanced force generated by a direct-acting driving portion of an engine and providing a damping actuator for generating damping force to cancel the inertia unbalanced force. CONSTITUTION:A vibration sensor 29 detects the vibrational acceleration generated at a direct-acting driving portion such as a power piston 18, a yoke 23b and the like to output it to a control circuit 30. The control circuit 30 which has received the above detection signal computes according to a designated control law for inverting the phases of the damping force generated by a damping actuator 28 and the inertia unbalanced force of the direct-acting driving portion to cancel each other and outputs a driving current to the damping actuator 28. Consequently, the damping force for cancelling the inertia unbalanced force of the direct-acting driving portion is generated by a damping force generating portion 28c. Accordingly, the vibration of a Stirling engine can be reduced to enable silent operation.

摘要： PURPOSE:To reduce vibration, by generating vibration suppressing force so as to reduce the vibration of a mounting bed, caused by a change of torque in an engine, by an actuator being based on the detection result of pressure in a cylinder chamber through a pressure sensor. CONSTITUTION:A change of pressure in a cylinder chamber is detected by a pressure sensor 18, and a signal of this change of pressure is amplified by a pressure gage 19 to an electric signal, having predetermined voltage, being input to a control circuit 20. The control circuit 20 sets its gain and phase characteristic so that predetermined control regulation is satisfied, that is, so that vibration suppressing force, generated from an actuator 17, negates or reduces a change of torque from a Stirling engine. Accordingly, the control circuit 20 regulates the signal from the pressure sensor 18 for its gain and phase driving the actuator 17 through a driving circuit 21. Vibration suppressing force in a direction of cancelling the change of torque in the engine is generated from the actuator 17 so that a mounting bed 15 reduces its vibration angular displacement.

摘要： PURPOSE:To obtain a compact vibration controller of a simple structure by providing a piezoelectric ceramic actuator having a control force producing face fixed to an object body together with an additional weight fixed to another face opposite to said object body. CONSTITUTION:A piezoelectric ceramic actuator 16 has an additional weight 5 having the prescribed weight fixed at the upper part with its lower end part fixed to a casing 15. This casing 15 is fixed to an object body 1 that undergoes the control of vibrations. An accelerometer 3 attached to the object body 1 detects the vibrations of the body 1 and an actuator impressing voltage controller 4 controls the voltage impressed to a piezoelectric ceramic actuator 14 based on the detected vibrations of the body 1. This impressed voltage produces the control force to the actuator 16 and this control force is transmitted to the body 1 by the force of inertia of the weight 5. Thus the vibrations of the body 1 are reduced effectively and the control properties of the body 1 can be improved.

摘要： PURPOSE:To effectively reduce the vibration of a vehicle body, by predicting the vibration mode of a vehicle body in accordance with the rotational speed of an engine and the weight of the vehicle body, and by controlling an actuator for applying damping force to the vehicle body in accordance with the result. CONSTITUTION:An engine rotational speed detecting circuit 8 is connected to an engine ignition pulse terminal 7, and a control circuit 9 in a control section 18 obtains a waveform having an amplitude and a phase which correspond to the engine rotational speed detected by the circuit 8. This waveform is compensated in accordance with the weight of a vehicle body detected by a weight detecting circuit 13 connected to a strain gage weight detector 12, and is then amplified by a power amplifier circuit 10, and thereafter is delivered to an actuator 6 which is constituted such that electromagnetic force that is generated when a coil 63 is energized, is transmitted to a casing 68 fixed to the vehicle body through a coil support 64. Thus, it is possible to aim at cancelling out torque variations caused by the rotation of the engine 1 with the use of the force from the actuator 6 to reduce the vibration of the vehicle body 4.

摘要： PURPOSE:To improve a feeling of driving comfortableness and durability in a controller, by driving an actuator with a detecting signal out of a vibration detector, while detecting a driving state, and interconnecting an empty space, where an elastic body exists, to an engine negative pressure part at the time of driving but selecting it to a positive pressure part at the time of stoppage. CONSTITUTION:An engine is discriminated as it is at idling or driving by an engine speed detector while a three-way valve is selected to where it should be, and a negative pressure port 25 is interconnected to a suction pipe at the time of driving and to a positive pressure part at the time of idling, respectively. At driving, an empty space 35 is made to come into suction pressure whereby a pressure differential between these spaces 35 and 36 grow large, pushing up a pressing device 23, and thereby a movable mass body 9 is locked thereto. On the other hand, at idling, the space 35 is interconnected to the positive pressure part, making the pressure differential between these spaces 35 and 36 dwindle away to nothing, whereby the pressing device 23 is pushed up and the body 9 is opened free, thereby making an actuator 6 come into a state of being operated. And, since the body 9 comes to a stationary state at the time of driving, any impact to a casing 18 due to vibrations in the body 9 and disturbance is avoided, thus no noise happens and service life is prolonged.

摘要： PURPOSE:To improve a feeling of driving comfortableness and durability ever so better, by driving an actuator with a vibration detector, while detecting a driving state, and selectively interconnecting an empty space, where an elastic body energizing a pressing device of a movable mass body is situated, to an engine negative pressure generating part and a positive pressure part. CONSTITUTION:An electric signal of the varying torque disturbance of an engine 1 detected by a vibration sensor 7 is inputted into a control circuit 8, feeding driving power of an actuator 6, and controlling force of the actuator 6 is impressed on a direction of damping vibrations in a car body 4, thus vibrations in the car body 4 are reduced. And the engine is discriminated as it is at idling or driving by an engine speed detecting circuit, feeding the control circuit 8 with an electric signal, whereby a three-way valve is operated, and at the time of idling, a negative pressure port 25 is interconnected to a suction pipe but at the time of driving, it is interconnected to a positive pressure part. Since a pressure differential between empty spaces 35 and 36 dwindles away to nothing and it grows larger the other way at the time of idling and driving, the actuator 6 locks a movable mass body 9 and pushes up a pressing device 23, opening it.
