A shock strut is disclosed. The shock strut may include a shock strut cylinder, a shock strut piston that is slidably disposed within the shock strut cylinder, a metering pin, and a percolation seal configured to restrict a flow of liquid between the shock strut cylinder and the shock strut piston.

A vehicle active vibration control (AVC) system includes a vehicle having at least an engine, a transmission, a controller area network (CAN) bus, a frame, and a cabin. The vibration control devices (120) are distributed about the frame, with each device including a circular force generator (CFG) (122). At least one sensor is positioned on the frame to detect and measure a noise and/or vibration within the cabin. Each sensor creates an electronic data signal and electrically communicates with a corresponding vibration control device. Each vibration control device receives an electronic data signal from a corresponding sensor and vehicle data from the CAN bus. Each vibration control device processes the electronic data signal and the vehicle data. The CFG of each vibration control device generates a vibration canceling force having a magnitude and phase that attenuates noise and/or vibration within the cabin.
