Problems solved by technology

[0003] The purpose of the present invention is to provide a kind of elastic multi-dimensional vibration damping platform based on the parallel mechanism of mixed kinematic pairs, which can eliminate the gap between kinematic pairs in the vibration damping platform and increase the vibration damping capacity of the mechanism, and improve the sensitivity of vibration damping. The disadvantage of poor mechanical performance of the mobile pair is used in the above-mentioned occasions that require multi-dimensional vibration reduction

Embodiment Construction

[0016] Such as figure 1 As shown, taking the three-translation damping platform as an example, a single open chain composed of three sets of R, R, R, P (4R□) pairs is connected in parallel between the upper and lower platforms. It consists of three parallel branches A 1 B 1 C 1 D. 1 E. 1 f 1 G 1 、A 2 B 2 C 2 D. 2 E. 2 f 2 G 2 、A 3 B 3 C 3 D. 3 E. 3 f 3 G 3 And upper and lower platforms. Such as image 3 , Figure 4 , Figure 5 As shown in Fig. 1, torsion springs and torsion-pendulum electrorheological fluid controllable dampers are added to the rotating pair of the driving parts to perform adaptive dynamic balance and absorb vibration energy to achieve the purpose of three-dimensional vibration reduction. Such as image 3 , Figure 4 The elastic damping device shown is the main device for the damping function of the damping system, and it is installed on the torsion spring 6 on the rotary shaft 4, the electro-rheological fluid controllable damper 7 an...

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

Technical field [0001] The invention relates to mechanical components, in particular to a kind of elastic multi-dimensional damping platform based on a hybrid kinematic pair parallel mechanism formed by combining a traditional kinematic pair and a reed, which is supplemented by a The torsion spring and the elastic damping device composed of the electrorheological fluid rotation controllable damper are used as a dynamic balance damping elastic damping system to form a multi-dimensional damping platform to achieve multi-dimensional damping. Background technique [0002] Multi-dimensional vibration reduction can be used for ambulance anti-vibration mounts, various vehicle chassis, engines, seats, tanks and ships in military systems, various precision instruments, meters, machine tools, test instruments in vehicles, ships, aerospace, etc., satellites Antennas, radar antennas, space telescopes, space interceptors, collimators, transportation of fragile, explosive, toxic and harmf...
