[0002] The vibration environment of helicopter shooting is composed of the inherent coupling vibration of the moving parts of the helicopter body platform and the instantaneous vibration of missile shooting. The coupled vibration of the moving parts of the body platform covers a wide range of vibration frequency intervals from low frequency to high frequency. The position is closely related, the traditional motion simulation platform is difficult to truly simulate the vibration environment of helicopter shooting, and the cost is very expensive

The invention relates to a helicopter shooting vibration environment simple platform simulation system which comprises a platform frame and a vibration simulation part. The platform frame comprises amovable table top, four limiting rods, an inflator, four supporting rods, a fixed table top and four air bags. The vibration simulation part comprises a longitudinal motor, a transverse motor, a vertical motor, a simulation computer, a speed sensor and an acceleration sensor, wherein the speed sensor and the acceleration sensor are installed in the x axial direction, the y axial direction and thez axial direction of the helicopter body. Coupling vibration of a machine body platform moving part and missile shooting instant vibration in a helicopter shooting state are collected on a transverseshaft. Vibration curves in the three directions of the longitudinal axis and the vertical axis are input into a simulation computer, corresponding driving signals are generated through the simulationcomputer to drive three motors on the movable table board of the platform frame to vibrate, vibration simulation of the movable table board in the three directions of the transverse axis, the longitudinal axis and the vertical axis is achieved, and the helicopter shooting vibration environment is well simulated and reproduced. And the system is simple in structure and low in cost, and has good popularization and application values.
Description
technical field [0001] The invention relates to a simple platform simulation system for helicopter shooting vibration environment, which belongs to the technical field of vibration simulation. Background technique [0002] The vibration environment of helicopter shooting is composed of the inherent coupling vibration of the moving parts of the helicopter body platform and the instantaneous vibration of missile shooting. The coupled vibration of the moving parts of the body platform covers a wide range of vibration frequency intervals from low frequency to high frequency. The position is closely related, and the traditional motion simulation platform is difficult to simulate the vibration environment of helicopter shooting, and the cost is very expensive. Therefore, it is of great practical significance to design a simulation platform that is simple in structure, low in price, and can truly simulate the vibration environment of helicopter shooting.
