Abstract

The invention provides a box-type three-degree-of-freedom stable platform based on a 3PSS-S parallel mechanism and a posture adjusting method thereof.The box-type three-degree-of-freedom stable platform comprises a platform rack, a hooke joint main shaft assembly and an upper platform assembly, the mounting end of a rack base is connected with an annular hanging table through a connecting arm, and a center ball head is arranged in the center of the annular hanging table. A first mounting end of the base is connected with the long vertical plate, a second mounting end of the base is connected with the linear guide rail, a third mounting end of the base is connected with the ball screw, a mounting end of the lead screw sliding block is connected with a first end of the spherical hinge seat, and a second end of the spherical hinge seat is connected with a first mounting end of the two-ball-head rod through a spherical hinge ball socket. The center of the posture adjusting plate is connected with the center ball head through the center ball socket, the installation end of the posture adjusting plate is connected with the first end of the edge ball socket through the ball hinge base, and the second end of the edge ball socket is connected with the second installation end of the two-ball-head rod. Unbalanced torque caused by rotation of the upper platform assembly is reduced, driving and freedom degree constraint are separated, and interference in movement is avoided.

Description

technical field [0001] The invention relates to the technical field of stable platforms, in particular to a box-type three-degree-of-freedom stable platform based on a 3PSS-S parallel mechanism and an attitude adjustment method thereof. Background technique [0002] With the innovation and development of my country's aerospace science and technology level and the growing strength of national defense, science and technology such as air transportation, air force mechanized operations, high-altitude scanning and detection have been given higher design requirements and expectations. a more innovative research mission. [0003] Aviation machinery and its mounted equipment are inevitably disturbed by high-speed airflow during navigation, and during flight, active control to adapt to changes in flight routes will also cause the body to change its attitude. These attitude changes make it difficult to obtain a stable working area in the cabin, which will have a certain impact on some...
