Abstract

The invention provides a leveling method for an air-floating platform based on six-point support. The leveling method for the air-floating platform based on the six-point support comprises the following steps that (20) six supporting points from 1# to 6# are arranged on the air-floating platform in a square matrix mode, and six supporting mechanisms are jointly used for supporting the air-floatingplatform; (30) height variation of the six supporting points from 1# to 6# is measured by an altimeter when counterweight blocks are placed alone; (40) according to the air-floating platform, six-points support is changed into three-point support, and the height value of the six supporting points from 1# to 6# are recorded by the altimeter; (50) three-point support is changed into four-point support, and the height variation is measured; and (60) four-point support is changed into four-point support, and the supporting mechanisms are adjusted. According to the leveling method for the air-floating platform based on the six-point support, the air-floating platform is evenly supported by six points, the support rigidity and levelness requirements of the air-floating platform are ensured, andthe stable support of the air-floating platform for space equipment is ensured.

Problems solved by technology

The levelness and support stiffness of the single-block platform are the main indicators for its regulation. The traditional leveling method mostly uses manual three-point leveling. Auxiliary jacking of the platform is carried out with multiple supports. The stiffness of the platform adjusted by this method is acceptable due to the position of the three-point support, but the position of the auxiliary support of the platform is often low in stiffness due to insufficient carrying capacity, and prone to edge collapse and leverage effects.

Tests with low requirements such as levelness and platform support stiffness can still meet the requirements, but for ground simulation equipment for large spacecraft weighing thousands of kilograms, the levelness and support stiffness of the air-floating support platform are often difficult to meet the index requirements
