Abstract

The invention discloses a high-precision two-degrees-of-freedom stable platform, which mainly comprises an upper layer of platform, a middle layer of platform, a lower layer of platform, a crank, a crankshaft, a crankshaft connecting piece, a middle layer of macro-axle and the like. The high-precision two-degrees-of-freedom can realize the motion of the two-degrees-of-freedom of rotating around an X-axis and rotating around a Y-axis, and can realize any of two-degrees-of-freedom composite motions at the same time. The test platform has the advantages of favorable stability, high precision, compact structure and low integral height, and is a simulated analogue device which aims attt the motion process under different sea conditions and other dynamic conditions, therefore, the invention is suitable for product tests in the national defense industry such as aviation, aerospace, weapons, ships, electronics and the like.

Description

technical field [0001] The invention relates to the technical field of ship testing, in particular to a high-precision two-degree-of-freedom stable platform. Background technique [0002] The two-degree-of-freedom stable platform is a simulation device for the motion process under different sea conditions and other dynamic conditions. It is suitable for product testing in defense industries such as aviation, aerospace, weapons, ships, and electronics. Throughout the country, traditional simulation platforms include six-degree-of-freedom and two-degree-of-freedom motion platforms. The shortcomings of the six-degree-of-freedom motion platform are: large structure, low utilization rate, and low precision; the traditional two-degree-of-freedom motion platform has a high structure and poor stability during high-frequency motion. Contents of the invention [0003] The object of the present invention is to provide a high-precision two-degree-of-freedom stable platform capable of...
