Abstract

The invention discloses a spatial redundant drive swinging experiment table with two degrees of freedom, which comprises a static platform at the bottom, wherein an upright post is fixed at the center of the static platform; the upright post is connected with a movable platform through a first Hooke joint; two second Hooke joints are arranged at one end below the movable platform in symmetrical positions and are respectively connected with a first drive hydraulic cylinder; the lower end of each first drive hydraulic cylinder is connected with the static platform through a third Hooke joint; the center line of the other end below the movable platform is connected with a second drive hydraulic cylinder through a fourth Hooke joint; the distance between the center of the fourth Hooke joint and the movable platform is equal to the distance between the center of the first Hooke joint and the movable platform; the lower surface of the second drive hydraulic cylinder is connected with the static platform through a fifth Hooke joint; each first drive hydraulic cylinder drives the swinging experiment table to swing transversely and longitudinally; and the second drive hydraulic cylinder cooperates with each first drive hydraulic cylinder to drive the swinging experiment table to swing transversely and longitudinally. By innovation of a mechanism and a drive method, the invention can meet the requirements of heavy load and high accuracy for the swinging experiment table in a ship simulation process and has the advantages of simple mechanism and convenient operation.

Description

technical field [0001] The invention relates to a swing test bench, in particular to a space two-degree-of-freedom redundant drive swing test bench. Background technique [0002] The swing test bench is a large-scale high-precision simulation equipment integrating mechanical, electrical, hydraulic, control instrumentation, sensor detection and other technologies. At present, rocking tables with various degrees of freedom are widely researched and applied at home and abroad. They can simulate various spatial positions and attitudes, and thus are widely used in training simulators with various functions, such as ship motion simulators, aircraft Flight simulators, car driving simulators, etc., and even space docking with spacecraft, radar signal tracking, and missile launch platform simulation. In view of its broad market prospects, domestic and foreign scientific research institutions have conducted extensive and in-depth research on the swing table in recent years, including...
