Description

Portable target space motion characteristic simulation platform for missile seeker
Technical Field
The invention belongs to the technical field of guidance heads, and particularly relates to a portable target space motion characteristic simulation platform for a missile guidance head.
Background
The seeker is a core component of the guided missile, and an optical system of the seeker receives information of a distant target, converges the information and converts the information into an electric signal to control an optical axis to follow and track the target. When the optical system main shaft rotates around the center of the universal bracket in follow-up. The infinite target characteristic is generated by a simulation target during indoor test, the simulation target is generally realized by a micro collimator, different light-emitting sources are placed on the focal plane of the collimator, parallel rays are formed after the light-emitting sources emit the light-emitting sources to obtain the infinite simulation target characteristic in different modes, and therefore indoor simulation targets such as laser, television, infrared and the like can be formed. During testing, the optical axis of the simulated target is aligned with the rotation center of the seeker to swing, the relative position and movement of the target and the missile are obtained, and target information is positioned in the visual field of the seeker and received by the detection unit, as shown in fig. 1.
The arrangement is shown in figure 2 when the seeker is tested indoors using a single axis turret. The rotation center of the seeker receiving unit is overlapped with the rotating shaft of the rotating table, the simulation target is located on the axis extension line of the seeker and can rotate around the rotating shaft within a certain angle range according to the required angle, angular speed and motion rule, response output information of the seeker is obtained by taking the simulation target as an input basis, and accordingly performance parameters of the seeker are obtained through processing. Because the signal response of the seeker is generally a yaw channel and a pitch channel, a target also needs to move in two directions during testing, and in the process of developing the seeker, the seeker is usually subjected to performance testing in the other direction after being circumferentially rotated by 90 degrees after testing in one direction is completed.
After the guided missile is assembled, the seeker is positioned at the top end of the missile body, the guided missile is arranged on the hanging rack or the support, the front part of the seeker is in a suspended state, the performance detection of the seeker and the ground performance detection of the guided missile can be generally carried out on a simple site, the requirements of a special detection rotary table of a general seeker on the use environment and the installation mode of a detected piece are relatively complex, and the test requirements under the state cannot be met.

The invention relates to a portable target space motion characteristic simulation platform for a missile seeker, which is used for testing the basic function of the seeker when a missile is suspended, realizing the test of the basic function of the seeker when a missile body is not dislocated and parts are not decomposed, and simultaneously simulating the target motion characteristic when the missile is electrified and tested.
According to the application characteristics and the test requirements, the invention provides a portable target space motion characteristic simulation platform for a missile seeker, which is used for installing a special simulation target and generating the motion characteristic of a simple target so as to achieve the basic performance detection of the missile seeker by combining with the real environment parameters in the actual engineering.
The purpose of the invention is realized as follows:
the platform comprises a tripod 1, a main angle plate 2, a turnover plate 4, a turnover motor 3, a swing plate 6, a swing motor 5, a simulation target 7, a balancing weight 8, a gear set, a bearing set and the like. And the external control box sends an instruction to realize the swinging motion and the channel turnover of the simulation target.
The invention is further described below with reference to the accompanying drawings.

And the outer side of the side plate of the main angle plate 2 is provided with a turnover motor 3. The bottom panel of the main corner panel 2 also serves to support the roll-over panel 4 and the components thereon. The turnover plate 4 is also of an L-shaped plate structure, and a side plate is fixedly connected with an output shaft of the turnover electrode 3 and can be turned over under the driving of the turnover plate; the swing plate 6 is placed on the upper surface of the bottom plate of the turnover plate 4, the outer side of the swing plate is connected with a swing shaft, and the lower end of the swing shaft penetrates through the bottom plate of the turnover plate 4 and is driven by a swing motor 5; the inner side of the wobble plate 5 is supported on the bottom plate of the roll-over plate 4 by means of bearings. The simulation target 7 and the output shaft of the turnover motor 3 are coaxially fixed on the upper surface of the swing plate 6.
The balancing weight 8 is fixed at the upper end of the side plate of the turnover plate 4 and is mainly used for balancing the dynamic moment of the turnover plate 4 so as to reduce the turnover head-up error; the main effect of the bearing is to overcome the strength deformation of the cantilever structure and reduce the friction of each rotating link so as to improve the rotating efficiency.
The channel overturning motor 3 provides a rotating moment for the overturning plate 4, the switching of a yaw channel and a pitching channel is carried out through the instruction of the control box, the overturning plate 4 achieves the position reaching of the yaw channel and the pitching channel under the action of the overturning motor 3, the swinging motor 5 provides power for the swinging plate 6 through a gear set, the simulation target 7 arranged on the swinging plate 6 swings around a rotation center under the instruction of the control box;

2) simple structure, portability and convenient use. The two-dimensional turntable can also realize two-channel testing, but the structure is relatively large and complex, the carrying and the installation are complicated, and the requirements on the field and the use conditions are higher, so that the two-dimensional turntable can achieve the effect of a two-dimensional channel through one-dimensional channel conversion, the structure is simplified, and the use conditions are reduced;
