A machine (10) for positioning an object (12) includes a movable part (16C) and a vibration reduction assembly (24) that couples the object (12) to the movable part (16C). Further, the vibration reduction assembly (24) reduces a magnitude of a vibration being transferred from the movable part (16C) to the object (12). The vibration reduction assembly (24) can include an actively controlled support system (30) and an actively controlled actuator system (32).

A solenoid comprises a mold coil, a housing, a yoke, an anchor, a cylinder, and an armature. The housing and the yoke are connected together with the cylinder intervening therebetween. The housing includes an accommodating tube portion including a first end portion, a second end portion, and a third end portion. The first end portion faces the anchor. The second end portion is axially recessed back from the first end portion and includes an abutting portion that abuts against the other axial end of the cylinder. The third end portion is axially recessed further back from the first end portion than the second end portion and accommodates solder (copper ring) for sealing space between the third end portion and the cylinder.

An electronically controller external damper reservoir assembly (eRESI) can be connected to a passive damper and/or substituted for an existing external reservoir to provide semi-active damping control. The eRESI includes a reservoir and a variable base valve assembly actuated by an actuator. A controller is in communication with the actuator and a sensor providing input signal indicative of vehicle movement and is programmed to generate a damping control signal to the actuator based on the input signal, to dynamically control the damping force outputted by a passive damper hydraulically connected to the eRESI. A P/T sensor can be installed to a gas chamber of a vehicle damper to generate a P/T signal indicative of the pressure and temperature of the gas. The controller is programmed to determine a damper position of the damper based on the P/T signal.

An active inertial damper system (100) and method for damping vibrations (V1,V2) in a structure (11). An inertial mass (2) is supported by a support frame (1) via spring means (3) to form a mass-spring system (2,3) having a resonance frequency (fn). A controller (6) is configured to control a force actuator (4) to adapt the driving force (Fd) as a function of measured vibrations (V1,V2). The controller (6) comprises a filter (H) determining a magnitude (M) of the driving force (Fd) as a function of frequency (f) for the measured vibrations (V1,V2) in the structure (11). The filter (H) is configured to provide an anti-resonance dip in the magnitude (M) of the driving force (Fd) at the resonance frequency (fn) of the mass-spring system (2,3) to suppress resonant behaviour of the mass-spring system (2,3) itself.
