Abstract

The invention relates to a vibration damping device, in particular to a multi-dimensional vibration damping device, which can be used in multi-dimensional vibration damping, anti-vibration, and vibration isolation systems. It is composed of a multi-degree-of-freedom parallel mechanism and a combined spring. Space type, the structure of the combined spring is composed of a spring and a damping system, the number of which is determined by the degree of freedom of the parallel mechanism, the main load direction (that is, the up and down direction) is equipped with permanent magnets to bear the main load in the up and down direction, and Further reducing the vibration in the up and down direction can effectively realize the vibration reduction of multiple degrees of freedom, without the need of a multi-layer structure, so that the overall structure is simple and the work is reliable.

Description

technical field

[0001] The invention relates to a vibration damping device, in particular to a multi-degree-of-freedom parallel mechanism combined elastic vibration damping device composed of a parallel mechanism and a combined spring. It can be used in multi-dimensional vibration reduction, anti-vibration, and vibration isolation systems, such as: three-dimensional anti-vibration system for stretcher supports. Background technique

[0002] If the stretcher bracket is directly rigidly connected with the vehicle body during use, it will be affected by factors such as road conditions, engine vibration, vehicle body starting and braking, and turning, and the vibration displacement direction of the stretcher bracket caused by it is three-dimensional. Vibration must also require three-dimensional vibration reduction. In order to solve this problem, the traditional method is to use multi-layer one-dimensional vibration reduction, which has a complex structure and is not reliable....
