Influencing Factors on Stick-Slip Behavior of a Ball Screw Driven Elevation Mechanism for MLRS
As an MLRS (Multiple Launch Rocket System) cage is moved with a uniform speed through an elevation mechanism for MRLS operated using ball screws,its stick-slip behavior can be observed by the friction in a ball screw actuator.In this study,a single-degree of freedom mathematical model of an MLRS elevation system is designed and its stick-slip behavior is analyzed using a friction force model considering the Stribeck effect.The stability of a vibration system is analyzed through deriving an equation of normalized motion for the mathematical model and the influences of mechanical parameters and friction parameters on the vibration response and stability are theoretically analyzed.
