COUPLED type four degrees of freedom simulation platform

COUPLED type four degrees of freedom simulation platform, which mainly comprises an upper platform, the platform and the platform structure connecting the two identical four drive legs and an intermediate branch constraints, which drives the motor branch of the lower base platform is fixedly connected to the motor and a speed reducer and secured, reducer base plate and a crank connected to a crank disk connected to the eccentric means by adjusting the stroke of the slider, one end of the connecting rod via a universal joint connected to the eccentric slide, the connecting rod the other end is connected via a ball joint on the internet; constrained intermediate branch is connected to one end of lower link lower platform and the other end connected to one end of the upper link, the upper link and the other end connected to the platform, which intermediate branch constraints on the sub-coat on the moving rod spring. The present invention is of simple structure, easy processing and assembling, can achieve the coupled movement, suitable for moving the ship the simulated vehicle.
