Arc track type virtual axis three-axis rotary table

Abstract

The invention discloses an arc track type virtual axis three-axis rotary table which comprises four parts including a direction real axis I part group, a rolling virtual axis II part group, a pitch virtual axis III part group and a stand, wherein the axial line of a direction real axis I is perpendicular to that of a rolling virtual axis II, and the axial line of the rolling virtual axis II is perpendicular to that of a pitch virtual axis III. Two virtual axes use arc tracks and rolling wheels to replace the traditional real axis rotation supporting system, so that serial movement connection is realized; by restraining the arc tracks by the rolling wheels, the arc tracks rotate around the corresponding virtual axes with a rack supporting structure together, so that movement of a rack is realized. Three-axis rotation of the rotary table is as follows: direction rotation is realized through a fixed vertical real axis; rolling rotation is realized through a first virtual axis; and pitching movement is realized through a second virtual axis. According to the arc track type virtual axis three-axis rotary table, circumferential rotation is realized by utilizing the arc tracks without adding counterweight, i.e. with balancing load, so that light weight of the rotary table is realized, the dynamic maneuvering performance of the rotary table is improved, and the loading ability and application places of the rotary table are expanded.

Description

technical field [0001] The invention relates to a device for simulating and adjusting attitude, in particular to a turntable which uses a circular arc track to realize rotation. Background technique [0002] As a device for simulating and adjusting attitude, the turntable has played an increasingly important role in modern military, industrial, aerospace and other fields. In the world, because the inertial guidance technology is generally valued by developed and developing countries in the world, and the turntable is an important non-standard equipment for testing inertial components and hardware-in-the-loop simulation, its performance directly affects the reliability of simulation and testing and confidence, so the United States, Russia, Britain, France, Switzerland, China, India and other countries have invested a lot of manpower and material resources in the development of turntables. In the decades since the first turntable was born in 1945, the important parts of the t...
