Mechatronic suspension system and method for shock absorbing thereof

A method for using mechatronic suspension system apparatus, comprising:

• using an inerter mechanism to transfer a linear motion into a rotational motion;
• using a permanent magnet electric machinery to generate a corresponding voltage according to an angular velocity of the rotational motion;
• and
• using a feedback circuit to provide a designed system impedance, adjusting an electric current and an inductive torque, and generating a suitable mechanical force.

A ball-screw inerter comprises:

• a nut;
• a screw;
• a flywheel for adjusting inertance of an inerter mechanism and being coaxial with the screw;
• a bearing;
• a bearing socket to fix the bearing;
• and
• a coupling coupled to an end of permanent magnet electric machinery to form the inerter mechanism.
