Description
Technical field
The invention belongs to vehicle suspension fields more particularly to a kind of slipper block connecting bar type variable comprising used matter coefficient to be used to container
ISD suspension system.
Background technique
Electromechanical integration is nowadays one important developing direction of engineering field.Between mechanical and electronic system there is
Corresponding relationship, one of which are that " force flow-electric current " is corresponding, i.e., the quality, damping and spring in mechanical system respectively with Department of Electronics
Capacitor, resistance and inductance in system is corresponding.Element in electronic system is all there are two free endpoint, but corresponding machine
In tool system, mass elements are a single-ended element, cannot be strictly corresponding with capacitor, to greatly limit electromechanical
Change theoretical application and development.
Cambridge University scholar SMITH, which has invented used container in 2000 and devised Ball screw type, is used to container and gear teeth
Formula is used to container.The it is proposed of used container concept is so that occur in mechanical system can be strictly corresponding with the capacitor in electronic system
Element, so that perfect electromechanical integration is theoretical.Later, used container is applied in F1 equation motorcycle race and significantly improves
The ground connection property of racing-car tyre.Especially used container improves the characteristics of vibrating in low-frequency range, is allowed to obtain extensively in each field
Concern and application, including automobile suspension system, wheel steering system, train suspension system and building vibrating isolation system etc..
