A Compensation Simulation Method for Turntable Applicable to Simulating Projectile Attitude Motion

Abstract

The invention provides a compensating simulation method for a turntable suitable for simulating the attitude motion of a projectile. By superimposing the sacrificial angle and the compensation angle method, on the premise of sacrificing the active range of the turntable's positive pitch angle, it solves the problems caused by the negative pitch angle. The problem of the mechanical angle limit of the turntable caused by too large angle meets the requirements of the hardware-in-the-loop simulation of the weapon system in the large-fall angle attack mode, realizes the closed-loop experiment of the weapon system hardware-in-the-loop simulation in the large-fall angle attack mode, and provides a basis for the weapon development of the guided rocket project Provided a strong guarantee.

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...
