The Design Of Stabilized Platform For Line-thrower Of Marine Salvage

Stable platform is a kind of device which is used to keep an object stability relative to a specific space coordinate.It can adjust the balance by collecting the motion information about vector and controlling the motor.It is important for modern engineering equipment,widely used in aviation,fire control systems of weapons and radar platforms.Aiming at the problem of low success rate of throwing rope rescue in marine rescue,this paper presents the application of stable platform to the emergency rescue rope-thrower system on rescue ship,to ensure the accuracy of projectile and the success rate of rescue.This paper analyzes the existing deficiencies of stabilized platform,on the basis of its main structure,the overall design ideas of a new generation of platform is proposed.According to the overall project goals,based on prototype,the processing product is already produced with related enterprises.Stable platform can effectively offset the movement of the hull depends on the performance of the impact resistance when the line-thrower launch.Therefore,this paper design structure system,including structure of platform frame,the type of drive and brake.Based on prototype,middle-frame uses O-series,up-frame uses U-series;Add a braking device between middle-frame and retarder,based on the count of recoil force.To simplify the coupling device,an expansion sleeve is designed in joint structure.In order to ensure the safety of service life,the strength of important parts are checked necessarily.In order to get the response time under different working conditions,import the platform of 3D modeling to ADAMS,dynamics simulation,observing and analyzing the torque output of motor sports curve and the motor output torque coupling condition,which provides a new platform for further optimization.
