Description
Technical field
The present invention relates to display and demonstration technical field, and in particular to a kind of bead bouncer.
Background technology
It is a kind of relatively conventional phenomenon that bead bounces on the load bearing member.The control that some acrobats pass through hand, energy
The performance for being some objects higher height of bob in a less scope is enough shown, so performance performance is performed
The control skill of member, to the sensation of the novel admiration of audience one.The good of attraction spectators has been combined in showgrounds such as show window, exhibitions
The strange heart also be intended to arrange some it is dynamic show scenes, than if allow bead to bounce on the bearing part for swinging, will be fresher
It is more interesting, can more cause the interest of people.Although theoretically, as long as the hunting period of bearing part is all with the bounce of bead
It is consistent that phase is designed, and the normal inclination angle of contact of the bearing part in contact bead every time causes the horizontal motion components of bead
It is in opposite direction, can both realize required demonstrating effect.In actual environment, it is contemplated that energy caused by air friction
Decay, by the motion of supporting body bead is applied appropriate energy compensating then can keep bead each jumping height and
Amplitude of fluctuation.But also there is the factor that many theoretical explanations are not involved with, can also produce impact to the drop point of bead, such as
The whether uniform factor of pellet quality, the factor of the carrying surface evenness of bearing part, and the compensation campaign direction of bearing part are deposited
Factor in deviation etc..The accumulation of these factors, can make bead be gradually deviated from bearing part, and then cause the failure demonstrated.
