Abstract

A fail-safe ride simulator (10) broadly includes a base (11), a platform (13) mounted for movement relative to the base, an actuation mechanism (14) operatively arranged between the platform and an actuation mechanism operatively arranged between the platform and the base. The actuation mechanism includes a plurality of electro-mechanical servoactuators (23) acting between the platform and base for causing relative movement therebetween. A fail-safe circuit (34) is operatively arranged to continuously monitor the condition of the actuation mechanism, and to cause the platform to move automatically toward a predetermined position relative to the base in the event of an unsafe condition in the actuation mechanism.
