A missile semi-physical simulation device

Abstract

The invention provides a semi-physical simulating device for a guide missile, and belongs to the technical field of guided missile simulating devices. A signal output end of a camera is connected with a signal input end of a missile guider; an output end of a simulating computer is separately connected with an input end of a three-axis rotary table and an input end of a ground rail system; an output end of the three-axis rotary table is connected with an input end of an angular rate gyroscope; an output end of the ground rail system is connected with an input end of an accelerometer; an output end of the missile guider, an output end of the angular rate gyroscope and an output end of the accelerometer are separately connected with an input end of an automatic driverscope; an output end of the automatic driverscope is connected with an input end of a rudder system; and an output end of the rudder system is connected with an input end of the simulating computer. An acceleration signal generated by the simulating computer is not directly input to the accelerometer, but input to the ground rail system. Motion of a practical guided missile is simulated through a control system of the ground rail system, and accelerated velocity of the rotary table is sensed through the accelerometer which is fixedly connected with the rotary table.

Description

technical field [0001] The invention relates to a missile semi-physical simulation device, which belongs to the technical field of missile simulation devices. Background technique [0002] The seeker is the core part of the image-guided weapon, its performance directly affects the guidance and flight control signals of the missile, and plays a key role in the missile's precision terminal guidance strike performance.

Problems solved by technology

However, the simulation of its acceleration is completed by directly transmitting the acceleration output signal of the computer to the accelerometer, and has not been materialized in the physical structure. The simulation and test of the missile acceleration are not realistic and accurate enough.

In addition, the input signal of the seeker is also calculated by the computer, and the physical simulation has not been realized.
