Abstract
A control mechanism for a simulator or stabilized platform comprising constant force spring device for supporting the weight of the platform and a plurality of impulsive force generating devices preferably in the form of electromagnetic linear rams although a rotary linkage driven by an electric motor would also work. The mechanism provides an agile arrangement at relatively low cost.
Claims7
An arrangement for controlling relative movement in a plurality of degrees of freedom between a platform and a reference plane comprising a fluid ram and pressurized gas reservoir for counterbalancing the weight of a platform, at least one electromagnetic impulse drive actuator in the form of a linear electromagnetic ram for applying an impulsive force between the platform and the reference plane, and control means for controlling the actuator to alter the instantaneous position or orientation of the platform with respect to the reference plane in a predetermined manner, wherein the fluid ram and the electromagnetic ram form a combined assembly.
