The invention discloses a hydraulic interconnection suspension system with a controllable inerter, and relates to the technical field of vibration reduction and isolation. The device comprises a hydraulic interconnection device, a motion transmission and conversion mechanism, an inerter controllable device and an external circuit. The hydraulic interconnection device comprises a hydraulic cylinder, a piston rod, an energy accumulator, a damping valve and the like, decoupling of vertical vibration and roll vibration can be achieved, and vibration energy is consumed by the damping valve. The motion transmission and conversion mechanism comprises a ball nut, a gear, a shell and the like, and linear motion of the piston rod is converted into rotation motion of the gear through the ball nut; the inerter controllable device comprises a direct current motor, an additional flywheel, a slip ring, a cover plate and the like, a part of vibration energy can be stored in the flywheel and used for low-frequency inertia damping, and the inerter is controllable by controlling electromagnetic damping through an external circuit. According to the suspension system, on the premise that only little vertical rigidity is increased, the non-linear roll rigidity is greatly increased, and energy is saved while the vibration reduction performance and the operation safety are both considered.
