Compensation type simulation method of rotary table suitable for simulating projectile posture motion

Abstract

The invention provides a compensation type simulation method of a rotary table suitable for simulating projectile posture motion. Through the method of stacking the sacrifice angle and the compensation angle, on the premise of sacrificing the positive pitch angle moving range of the rotary table, the problem that the mechanical angle of the rotary table is limited due to the too large negative pitch angle is solved, the weapon system semi-physical simulation requirement under the large-fall-angle attack mode is met, the weapon system semi-physical simulation closed-loop experiment under the large-fall-angle attack mode is achieved, and powerful guarantees are provided for weapon development of the guided rocket project.

Description

technical field [0001] The invention belongs to the technical field of guided weapon simulation, and in particular relates to a compensating simulation method for a turntable suitable for simulating the attitude motion of a missile body. Background technique [0002] The turntable has the function of simulating the attitude movement of the projectile body, and is an indispensable part of the test equipment for the semi-physical simulation test of the guided weapon system. The vertical turntable is a type of turntable divided according to the form of mechanical structure, which meets the omnidirectional launch requirements of the rocket-guided weapon system. [0003] Traditional hardware-in-the-loop simulation methods for weapon systems include the following steps: [0004] S1: Fix the inertial navigation device on the vertical turntable, and bind the initial projectile attitude information (θ 0 、ψ 0 , γ 0 ), initialize the attitude angle of the turntable, and wait for th...
