Abstract

The present invention provides a shock absorber capable of improving energy efficiency for attenuating input vibration corresponding to an unsprung resonance frequency and a sprung resonance frequency, and a method of manufacturing the shock absorber. In the shock absorber (22), the electrical resonance frequency determined according to the inductance (L) of the electromagnetic motor (66) and the capacity (C) of the capacitor (70) is set within ±20% of the unsprung resonance frequency, thereby In addition to suppressing the input vibration corresponding to the unsprung resonance frequency, the input vibration corresponding to the sprung resonance frequency is also passively suppressed.

Description

technical field The present invention relates to a shock absorber for regenerating input vibration energy and a method for manufacturing the shock absorber. Background technique In U.S. Patent Application Publication No. 2004 / 0150361 (hereinafter referred to as "US2004 / 0150361A1"), the object is to provide an electromagnetic suspension device for a vehicle capable of controlling the input of a control object. Active control can also passively treat inputs other than the control object, so that not only the active control becomes simple, but also the energy efficiency can be improved ([0003] to [0005]). In order to achieve this purpose, the vehicle electromagnetic suspension device of US2004 / 0150361A1 (Abstract, FIG. 3 ) is provided with an electromagnetic actuator 4, and the electromagnetic actuator 4 and the spring element 7 are clamped between the upper spring and the lower spring in parallel. Between, and driven by electric motor 8. The motor controller 17 is configure...
