A Continuously Variable ER Damper with Energy Generation

초록

This paper presents an energy regenerative ER(electrorhoelogical) damper which does not require external power sources. The ER damper has a rack and pinion mechanism which converts a linear motion of the piston to a rotary motion. This rotary motion is amplified by gears and subsequently activates a generator to produce an electrical energy. The level of the electrical voltage produced from the generator is evaluated with respect to the rotational speed. The voltage is then amplified via the high voltage amplifier and regulated as a d.c. high voltage through the a.c./d.c. transformer. After investigating the level of the generated high voltage, the damping force of the ER damper is evaluated with respect to the piston velocity.
