Definitions
- the invention relates to a device for damping periodic movements of a body or a mass, in particular vibrations, with a housing fastened to this body or this hate, which contains a damping body that is movable relative to the housing and is under the action of spring force.
- the known vibration dampers have in common that their movement can be calculated in a good approximation by means of a linear movement equation.
- a vibration damper which consists of a closed cylinder, which is on the top ren and lower end each has a fixed spring.
- a damping weight located in the cylinder is slidably movable between these two springs, whereby the direction of movement of the damping weight and its force absorption is determined in only this axial direction.
- the object of the invention is to provide a vibration damper that can be produced in a simple construction and is capable of periodic movements of a body, be it an extension initiated by a single deflection from the rest position. vibrate, be it a continuous vibration, damped in a shorter time and more effectively than is possible with the conventional devices.
- a device is proposed according to the invention, as described in the main claim. Due to the spring elements which are used and which are at least unfastened on one side, there is a margin between them and the end faces of the damping body and the inner walls of the front sides of the housing. This results in a temporal phase shift in each oscillation period, which can only be approximated by the nonlinear differential equation.
- the advantage of this invention over the prior art is the possibility given by the non-linear equation of motion that the damping body receives a phase shift in each period of the vibration to be damped, which, with suitable adaptation, leads to almost complete antiphase every subsequent oscillation period and makes the vibration damper an active oscillator. With a suitably chosen ratio of the mass of the body to be damped to the damping mass, this means that the vibration is damped faster than in the prior art.
- the device according to the invention When the device according to the invention is used as a shock absorber, not only is the vibration initiated by the force shock damped, but the first deflection is also reduced.
- the non-linearity of the equation of motion of the damping body is ensured by the fact that the spring elements each on an end face of the damping body or on an inner wall. d ng are hinged to one end of the housing. The other end of the spring elements remains unsecured, so that in the middle position of the damping body there is a clearance between the spring elements on the one hand and the end faces of the damping body on the other hand, or the inner walls of the front sides of the housing. Depending on the width of this range, and thus the unsprung path of the damping body, there is a phase shift in each oscillation period.
- the design of the spring elements as helical springs or leaf springs is expedient. Their guidance is unproblematic, and their inherent stability also allows a large margin between the spring and the damping body or the front face of the housing.
- Another refinement of the invention consists in the fact that adjustable electrical or magnetic fields which serve as spring elements are used to produce energy-saving electrical vibration generators.
- This enables an electronically controlled adaptation of the non-linear part of the equation of motion of the damping body, which ensures easy manipulation of the phase shift of the vibrating damping body even during each individual oscillation period and causes a faster and more effective reaction.
- the special thing is that the energy required for this is obtained using the kinetic energy of the vibration exciter.
- the housing of the device according to the invention is advantageously designed to be gas-tight and liquid-tight, so that the medium can have atmospheric pressure, negative pressure or positive pressure on one or both sides of the damping body. It is thereby achieved that a medium filling the housing interior is compressed by a movement of the damping body in the housing section lying in the direction of movement, and can expand in the housing section lying opposite to the direction of movement.
- this medium is a liquid, preferably an oil, the pressure difference that forms has an advantageous damping effect on the vibration of the damping body.
- the medium filling the interior of the housing consists partly of a liquid, preferably an oil, partly of a gas. Due to the different speeds of flow past or through the two partial media around or through the damping body, an additional non-linearity in the equation of motion is obtained in the case of large deflections of the damping body in which the gas is almost completely displaced on one side.
- the aim is to keep the frictional forces between the parts of the device moving against one another to a minimum; in special cases, however, it can be expedient to design the surfaces of the damping body and the inner wall of the housing in such a way that the friction between the surfaces brings about additional, significant damping.
- the damping body which is not accelerated from the outside or from the spring elements, is brought into the central position by a centering element and held there.
- Another advantageous embodiment consists in the point or axisymmetric design of the device, so that the spring elements from the position point or the position point axis, i. H. the center or the center axis of the point or axis-symmetrical damping body are arranged starting from a beam.
- Such a geometric shape makes it possible to dampen the movements of a body vibrating in several spatial directions with a single device according to the invention.
- the space of the medium is expediently divided into individual, segment-like sections by pressure-tight bulkhead walls permitting the movement of the damping body, each of which is connected through or around the damping body to the diametrically opposite section.
- a modified solution to the problem on which the invention is based consists in the use of the entire device according to the invention as a damping body of a direction arranged second device. It is thus also possible to achieve vibration damping which acts in several dimensions and is brought about by a uniform device.
- FIG. 2 shows a section according to FIG. 1, the housing being partially filled
- FIG. 3 shows a section through another embodiment of a rectangular vibration damper
- FIG. 5 shows a section through a cuboidal vibration damper, the damping body of which is a further vibration damper.
- the damping body 1 is located in the middle of the housing 2, as a result of which the clearance 6 between the spring elements 5 articulated on the end faces 4 and the inner walls of the housing end faces 7 is visible in both spring elements.
- the medium 3 filling the interior of the housing can flow past the damping body through the gap 13.
- the interior of the housing is largely filled with a liquid 9 in FIG. 2 and with a gas 8 for the rest.
- the exemplary embodiment of the vibration damper according to the invention according to FIG. 3 contains only a spring element 5 which is articulated on the end face 4 of the damping body 1 and is attached to the end face of the housing 2 in such a way that there is a play space 6 for each direction of movement of the damping body 1 is available.
- Fig. 4 shows an axisymmetric embodiment according to claim 12.
- the damping body 1 and the housing 2 are circular disk or circular cylindrical shape; the circular-disk-shaped or circular-cylindrical shape can also have spherical or oval-shaped, center-centered curved end faces on both sides or on both ends.
- the spring elements 5 are arranged radially starting from the center 10 (or central axis) of the damping body 1, the space of the medium 3 being divided by partition walls 11 into individual, segment-like sections 12 which are circular or rectangular or can have trapezoidal shapes.
- the housing 2 with the damping body 1 and spring elements 5 as the second damping body 14 according to the invention is accommodated in a second housing 15 such that the respective directions of their damping effects are perpendicular to one another.
- the second damping body 14 has a vibration-damping effect on the second housing 15.
- FIG. 6 shows a numerically calculated path-time diagram of the decay behavior of two coupled, equally heavy oscillating masses, the movements of which are represented by curves 16 and 17.
- Mass 17 is at rest at time t-0, mass 16 is deflected by 1 skt at time t-0. Any damping effects are neglected.
- FIG. 7 shows a path-time diagram calculated analogously to FIG. 6, the mass 17 being provided with damping as an additional parameter.
- FIGS. 6 and 7 show an example of the advantageous effect of the invention.
- a decay behavior of two coupled, equally heavy oscillating masses 16 and 17 is shown, and as in FIGS. 6 and 7, the mass 17 is in its rest position at time t-0, the mass 16 but deflected by 1 skt.
- the oscillation behavior of the mass 16 is described by a linear equation of motion, damping effects being neglected, the oscillation behavior of the mass 17 being different, in contrast to FIGS. 6 and 7, according to the invention described with a non-linear equation of motion.
- the vibration of the mass 17 is damped as in FIG. 7.
