摘要:
A motion assembly that produces pitch and roll motions includes lower and upper plates. A pivotable coupling having upper and lower shafts extending from its center is coupled between the upper and lower plates. At least two linear actuators are coupled between the plates. Extension and retraction of the actuators pivots the upper plate about the pivotable coupling relative to the lower plate. A vehicle includes two steerable propulsion wheels coupled to a chassis. A lower plate of a pitch and roll assembly, similar to that just described, couples to the chassis via a slew bearing. Seating is coupled to the upper plate. The seating rotates with respect to the chassis via controlled rotation of the slew bearing with reference to the chassis. The seating can be rotated to point in any direction with respect to the chassis regardless of the direction the steerable propulsion wheels move the chassis.

Each of slide duct devices which are attached to actuators (38A and 38B) constituting each vibration device includes a cableveyor (42A) through which a wire/ductwork material group (WH) is inserted, a guide duct (40A), and a slide rail unit (SLU) slidably supporting the guide duct (40A). A swinging base (12) connected to the actuators (38A and 38B) has a wire/ductwork material alignment mechanism (50) enabling alignment of the wire/ductwork material group (WH) passing through the guide duct (40A) without damaging the same.

A motion simulator (10) has a body tub (12) fixed on a carrier platform (14), the carrier platform being supported via motion control apparatus (52, 54, 56, 58), each having bearings which translate along an inclined path, the motion control apparatuses together providing six degrees of motion for the carrier platform.

The motion simulator of the present invention comprises: a base frame; a support member arranged above the base frame so as to support a monitor and a handle; a first link part, the top of which is connected to a rear end of the support member such that the top of the first link part can rotate in roll and pitch, and the bottom of which is connected to a rear end of the base frame such that the bottom of the first link part can be rotated in pitch, the first link unit transmitting the power from first driving units so as to move the rear end of the support member in the upward and downward directions; a second link part and a third link part, the tops of which are connected to the left and right ends of the support member, respectively, such that the tops of the second and third link parts can be rotated in roll and pitch, and the bottoms of which are connected to left and right sides of the base frame, respectively, such that the bottoms of the second and third link parts can be rotated in roll and pitch, the second and third link parts transmitting the power from second driving units and third driving units so as to move the left and right sides of the support member in the upward and downward directions; and a fourth link part, the two ends of which are linked to the first link unit and to the base frame, respectively, such that the two ends of the fourth link part can be rotated in pitch, the fourth link part transmitting power from fourth driving units so as to rotate the first link part in pitch.
摘要:
The invention relates to an assessment method for assessing acceleration behaviour of a driver of a vehicle. The method comprises determining the vehicles acceleration a, calculating one or more threshold values for its acceleration which depend on at least one situation-specific parameter, comparing its acceleration a with said one or more threshold values, and generating on the basis of the comparison a grading signal related to said calculated one or more threshold values. The invention relates also to an assessment system for assessing acceleration behaviour of a driver of a vehicle.
