Abstract
The invention is an elastic multi-dimension damping desk based on sires and parallel pair parallel mechanism; it is made up of the parallel mechanism of the whole rotation pair, the active rotating pair uses the traditional type, the other rotating pair uses the reed, in order to eliminate the gap among pairs. A torsion spring and a rotary controllable damper are added at the active rotating pair, which is used to self-adaptable power balance and absorb the vibration energy, achieves the aim of high sensitivity multi-dimension damping, overcomes the deficiency that the stress performance of the moving pair is bad, it can be applied to ambulance damping frame, car plate, engine, base, tank, ship in military system, each kind of precise instruments and satellite antenna, radar antenna, space telescope, space interrupter, aiming sight, and transmission of crushable, explosive and harmful materials.
Description
Affiliated technical field
The present invention relates to mechanical component, refer in particular to the One kind of flexible multi-dimensional vibration reduction platform which based parallel-series kinematic pair parallel mechanism that utilizes conventional motion pair and spring combination to form the series parallel type kinematic pair, it rotates vice division chief at the mechanism driving link and is aided with torsion spring and rotates elastic damping device that controllable damper forms as dynamical balancing damping elastomer damped system by electrorheological fluid, constitute multi-dimensional damping platform, realize multidimensional vibration reduction.
Background technique
Multidimensional vibration reduction can be used for the ambulance Shockproof rack, various types of vehicles chassis, motor, seat, tank, naval vessels in the military system, all kinds of precision type instrument, instrument, lathe, vehicle-mounted, boats and ships, test instrument in the Aero-Space etc., satellite antenna, radar antenna, space telescope, space blocker, pointing instrumentation, occasions such as frangible explosive poisonous and harmful object transportation.According to the retrieval, relevant patent has Chinese invention patent, and number of patent application 02137948.3 " multi-freedom parallel mechanisms combined elastic vibration clamper " utilizes the multidimensional vibration reduction device with conventional motion pair of tension and compression cluster spring and mobile damping device; China's utility model patent, the patent No.: ZL02258129.4 " imitative rubber multi-freedom degree elastic damping vibration damping equipment ".Mechanism in these two patents is the secondary mechanism of ordinary movement, the flexible joint kinematic pair that does not contain any reed-type, and the elastic element of vibration damping is drawing-pressing spring and tension and compression damped system, is not based on torsion spring and reverses the vibration damping of damped system, and effectiveness in vibration suppression is not very good.
Summary of the invention
The purpose of this invention is to provide One kind of flexible multi-dimensional vibration reduction platform which based parallel-series kinematic pair parallel mechanism, can eliminate the pair clearance in the vibration reduction platform and increase mechanism's damping capacity, and the sensitivity that improves vibration damping, overcome the shortcoming of sliding pair stress performance difference in addition, be used for the above-mentioned occasion that needs multidimensional vibration reduction.If several these type of vibration reduction platforms are carried out reasonable combination, also can further enlarge its application area.
The technical solution adopted in the present invention is: the revolute pairs of using in the paralleling mechanism that vibration reduction platform is used more, and wherein the non-active tradition of part revolute pair adopts reed to connect two reed-type revolute pairs that member forms, and itself and traditional revolute pair are formed the series parallel type kinematic pair.Torsion spring and electrorheological fluid controllable damping system are installed additional in the active rotation vice division chief of former paralleling mechanism.
And in the paralleling mechanism that vibration reduction platform is used, can only use revolute pair.
Its advantage is:
The elastic damping system of entire mechanism is in order to absorbing vibrational energy, and both to reduce the vibration damping that pair clearance causes blunt as far as possible thereby reach, and avoids the shortcoming of the easy self-locking of sliding pair stress performance difference again, and then make the multidimensional vibration reduction effect even more ideal.
