Definitions
- the height of the sidewalls takes into account the stiffness, whereby it has to be taken into account that a vertical elevation with otherwise the same geometry increases the rigidity and thus also the natural frequency. This is the reason why the conventional way of increasing the stiffness of a sidewall is to increase the vertical height of the respective sidewall.
- the nodes are also known as Bessel points.
- the nodes of vibration fall on Bessel points which, with regard to moment, inclination and deflection, represent optimum bearing positions of a uniformly loaded carrier, or in the present case a cross member, at two bearing points.
- the respective two vibration systems are arranged on the respective side wall such that each vibration system is arranged in the region of a vibration node of the first bending mode of the respective side wall.
- a eigenmode can only be excited if the excitation frequency is not initiated in the vibration node. It therefore corresponds to the doctrine of the invention, the components of the screen system, in particular the trusses and the side walls, not to have to dimension considerably larger, if directly the formation of the first eigenmode is prevented. Since the vibration systems are thus arranged in the region of the vibration nodes, it follows that the exciting frequency of the vibration systems is not introduced into the side walls in a bending-forming manner.
- the sieve system (1) has a sieve box (2) which comprises two outer side walls (31, 32).
- the side walls (31, 32) are in particular mirror-symmetrical, so that they do not differ significantly.
- the side walls (31, 32) are arranged parallel to one another.
- the two side walls (31, 32) to a vertical mirror plane extending along a conveying direction (F) are arranged mirror-symmetrically to each other.
- the respective two vibration systems (4) are arranged on the respective side wall (31, 32) such that each vibration system (4) overlaps a vibration node (S) of the respective side wall (31, 32). More precisely, the respective two vibration systems (4) are arranged on the respective side wall (31, 32) such that each vibration system (4) is arranged in the region of a vibration node (S) of the first bending mode of the respective side wall (31, 32).
- the screen (1) has a control system, not shown here, which is connected to the unbalance drives in order to set phase offsets of the unbalance drives.
- 5 and 6 show in a schematic side view, the side wall (31 or 32) of the screening system (1) according to the invention with illustrated vibration node (S) of the first bending mode, wherein FIG. 6 is a simplified view of FIG.
- the bending modes are shown simplified by lines.
