Abstract
The utility model relates to a rubber-imitated damping device with multiple degrees of freedom, which can be applied to multidimensional damping and vibrationproof systems, such as three-dimensional vibrationproof systems for stretcher supports. The utility model is formed by the technical scheme that springs and a damper are additionally installed on the original motive part by a parallel mechanism 3-PRC with three degrees of freedom, and permanent magnet steel and the damper which is composed of conductive body cutting magnetic lines are matched between a dynamic and a static platforms, namely in the direction of main load. The utility model is used for bearing the main load in an upper and a lower directions, and for further improving the vibration in the upper and the lower directions. The damping device can effectively imitate rubber damping in multiple directions and does not need a multilayer structure, and can overcome the defects of easy aging, elasticity loss, etc. of the rubber. The three-dimensional damping device has the advantages of good damping effect, long service life and reliable operation.
Description
Affiliated technical field
The utility model relates to a kind of elastic damping vibration damping equipment, refers in particular to imitative rubber multi-freedom degree elastic damping vibration damping equipment, can be used in the anti-vibrating system of multidimensional vibration reduction, as: the three-dimensional of litter frame is prevented vibrating system.
Background technique
The patient uses litter frame as directly connecting with rigidity of vehicle body, be subjected to that road conditions, engine luggine and car body open braking, the influence of factor such as turn round, and the vibration displacement direction of the litter frame that causes is three-dimensional, and therefore, it is carried out vibration damping must also need three-dimensional vibration damping.In order to address this problem, traditional scheme mainly contains two kinds: a kind of is to adopt multilayer one dimension vibration damping, complex structure, and unreliable.Japan Patent " vibrationproof ベ ッ De ", special flat 6-184894 of Willing of number of patent application and patent " Shockproof rack for ambulance ", the anti-vibrating system that is single-degree-of-freedom linkage mechanism composition that number of patent application 99123143.0 proposes or two layers of anti-vibrating system that the single-degree-of-freedom linkage mechanism is formed.This scheme does not solve three-dimensional vibrationproof problem, and because increase with the number of plies, structure is more complicated, and system weight also increases thereupon, so the reliability variation.
Another kind is to adopt rubber pad to realize multi-degree of freedom vibration reduction, but that its elasticity is influenced by rubber performance is very big, and rubber is aging easily and follow the string, so its vibrationproof performance is also undesirable.
Summary of the invention
The purpose of this utility model is the multi-freedom degree elastic damping vibration damping equipment that a kind of imitative rubber will be provided.This purpose can realize by following measure:
The structure of this vibration damping equipment has one by three parallel branch (P
1R
1C1), (P
2R
2C
2), (P
3R
3C
3) and the 3-freedom parallel mechanism 3-PRC that forms of moving platform, silent flatform, every route rod member connects by sliding pair P, revolute pair R, cylindric pair C and forms.For reaching the vibration damping purpose, paralleling mechanism sliding pair P is equipped with at the place and outer spring and damped system of carrying balance, forms elastic floating and supports.The elastic floating that is made of damper and the permanent rare earth magnetic steel that repels each other is housed between moving platform and the silent flatform supports, to bear main load and further vibration damping, this magnet steel has high magnetic conduction power, and average per in theory 7 gram rare earth magnetic steels can produce 5 thrust-kilograms.U magnet is housed on the silent flatform, a damping plate is housed on the moving platform, be used for cutting magnetic line and form damper.
For guaranteeing performance and reducing volume, (be three slide block P on the silent flatform with three driving links
1, P
2And P
3) change the opposite one-sided tension and compression spring of rotation direction into bilateral extension spring between the frame, be equipped with damper, just can realize x, the y of rubber like, the comprehensive vibration damping of three directions of z.
Decide through designing and calculating and test result outer year of will bear by system of the damping constant of relevant spring rate and damped system, and mechanism's yardstick needs to determine by dynamic optimization design, to avoid bad reflection such as resonance.
For guaranteeing the safe and reliable of system, when the degrees of freedom of paralleling mechanism was 3, its driving link place spring-damper sum also was 3.
The beneficial effects of the utility model are:
1, device can be realized three-dimensional vibration damping, promptly before and after, up and down, about vibration can be simultaneously controlled, especially main load direction (being above-below direction) is equipped with the permanent-magnet steel of being made up of rare earth material and has further strengthened balance and vibration damping.
2, this device has also solved the drawback that the spring damping of in the past forming with permanent-magnet steel needs the directional post support well, and the cancellation directional post has overcome the shortcoming that influences damping property because of the directional post friction.
3, it is easily aging and follow the string that this device has overcome the rubber vibrationproof, and vibration-isolating effect relatively limits to shortcoming.
4, this device deft design, overall structure is simple, and reliable operation is easy to use, and is cheap.
