Abstract

The invention discloses an eight-supporting-point leveling method for a rocket launching platform. The method comprises the following steps: (1) analyzing stress situations under different working conditions, determining eight stress supporting points, and mounting leveling support legs on the supporting points; (2) determining a leveling reference point, measuring the ground height values of other supporting points, calculating the height differences between the other supporting points and the reference point, namely, the total extension amount of the support legs, converting the total extension amount into the rotation circle number of the support legs, and calculating the leveling accuracy of the other supporting points according to dynamics simulation, platform structural simulation and the positions of corresponding supporting points; (3) lifting the platform till the supporting points are suspended, and adjusting the extension and retraction of the support legs in sequence according to the rotation circle number till the requirement of the leveling accuracy is met; (4) lowering the platform till the support legs are landed to finish leveling. By adopting the leveling method, the structure of a leveling system is simplified, operation becomes easy and convenient, and the leveling accuracy is high.

Description

technical field

[0001] The invention relates to a launching device for launching bullets or missiles by its own tube, in particular to a launching device for rockets. Background technique

[0002] Most of the existing rocket launch platforms are integrated with vehicles, and most of the platforms are leveled by 4 fulcrums and supported by 4 to 6 fulcrums. The outriggers at the fulcrum are usually controlled by hydraulic control or electric control for platform leveling, and in-position switches or angle sensors are set on the outriggers. Such a leveling system has a complex structure and has high requirements for the leveling control system. For example, the automatic leveling system disclosed in the Chinese invention patent with the notification number CN101017074B uses the high sensitivity and high adjustment accuracy of the electrolyte sensor to send the uneven signal of the platform to the control part of the automatic leveling system, so that the angular displacement be...
