Object under force balance state and vibration control and posture adjustment method for object

Abstract

The invention provides an object under a force balance state. The object comprises a subject main body, a structural body array and a connector; and a plurality of structural bodies are sequentially connected through a variable-rigidity active execution part. The invention further provides a corresponding vibration control and posture adjustment method which comprises a vibration control step on a transmission path, a dynamic vibration absorption step based on variable-rigidity damping characteristics and an auxiliary posture adjustment step. The object is the variable-rigidity execution part based on structure-function integration, damages on a plate-shaped structure main body, and even the subject main body are avoided, and a control algorithm is simpler and more effective; active vibration suppression can be separately carried out on disturbance from a plate-shaped structure, and active dynamic vibration absorption is carried out on vibration from the subject main body; and the method can be carried out at multiple frequency bands and in multiple freedom directions; and posture of the subject can be adjusted in an auxiliary manner.

Description

technical field [0001] The present invention relates to vibration control technology, in particular, to a control scheme for vibration and attitude adjustment of a target object in a state of force balance such as inertial suspension with a structure such as a plate structure, especially related to dynamic vibration absorption technology and integrated design of structure and function Technology and force balance state of the object attitude adjustment control technology scheme. Background technique [0002] The problem of vibration control of objects under force balance has always been a difficult problem in engineering applications; the integrated design of structure and function is a major trend in the current engineering application field, especially in the aerospace field. At present, the research on the vibration control method of objects under the state of force balance mainly focuses on the research on the plate structure body, by installing smart materials on the pl...

AI Technical Summary

Problems solved by technology

At present, the research on the vibration control method of objects under the state of force balance mainly focuses on the research on the plate structure body, by installing smart materials on the plate structure, such as piezoelectric ceramic strain gauges, shape memory alloys, etc., or installing dampers etc. to improve the vibration pattern of the plate structure, so as to realize the vibration control of the target body. Although this vibration control method has certain effects, it will bring problems such as structural damage and weight increase.

At present, jet vector propulsion technology is widely used for attitude adjustment of inertial suspensions, but this control method will be limited by fuel, etc., and in some specific cases, it cannot be launched

[0003] At present, there is no description or report of the similar technology of the present invention, and no similar data at home and abroad have been collected yet.
