A parallel attitude adjustment vibration isolation composite platform

Abstract

The invention relates to a parallel adjusting vibration isolating composite platform and belongs to the technical field of parallel mechanism application. A movable platform, a machine frame and three main branch chains compose an adjustment stabilizing platform; by drying the moving pair of the main branch chains, the movable output of twice movements and one translation of the platform can be achieved, so that the platform can maintain a stable working stable; the movable platform, the machine frame and six elastic branch chains compose a multi-dimensional vibration isolating platform, medium and high frequency vibration of the machine frame can be absorbed by springs of the elastic branch chains to achieve a multi-dimensional vibration isolating function. The parallel adjusting vibration isolating composite platform is skillful in design and simple and compact in structure and can solve the problem of posture adjustment and multi-dimensional vibration isolation simultaneously.

Description

technical field [0001] The invention relates to a parallel posture adjustment and vibration isolation composite platform. Specifically, a two-layer parallel mechanism is used to realize platform posture adjustment and multi-dimensional vibration isolation, which belongs to the parallel mechanism application technology. Background technique [0002] The parallel mechanism is usually composed of a dynamic platform, a static platform (frame) and a number of branch chains distributed between the two platforms. It has the advantages of high rigidity, fast speed and high precision. It has been widely used in industrial robots, motion simulators, parallel machine tools and other fields. widely used. [0003] In recent years, stable platforms and multi-dimensional vibration isolation platforms based on parallel mechanisms have attracted widespread attention from scholars at home and abroad, and relevant applied research has begun. Its working principle is that when the static platf...

Problems solved by technology

[0004] However, the excitation environment in actual engineering is relatively complex, and high and low frequency vibration excitations coexist, such as offshore platforms, ships, space capsules, engineering vehicles and other application fields. It is necessary to maintain the working attitude of the platform and weaken the multi-dimensional vibration.

At present, there is no multi-functional equipment with attitude stability and multi-dimensional vibration isolation at the same time.
