Rail guns are serious contenders for future naval weapon systems because of their ability to overcome the speed limitations of chemically propelled shells. Muzzle velocities in excess of 2km/s are achievable by rail guns and this provides ranges far in excess of current capability. In addition this speed allows the kinetic energy of around 60 MJ alone to provide the destructive effect. The absence...
A co-simulation method for rigid-flexible coupling system is proposed in this paper, it is simple and easily carried out. In order to solve the dynamics of 3-TPT parallel robot more accurately, its three driven links are regard as flexible bodies and the other parts are rigid bodies to form the rigid-flexible coupling system, and the dynamics equation of the coupling system is educed by Lagrange's...
Aerostatic thrust bearings are used in linear guideways as an alternative to contact bearings. The absence of friction in the motion makes aerostatic guideways most suitable for high precision and high speed machines. The low stiffness and damping of the aerostatic support limits their application to machining processes. Active compensation, applied to the bearing films, is proposed as a solution...
