A bending strain measurement apparatus for an abdomen of an anthropomorphic dummy comprises a band constituted of an elastic thin plate member. The band is arranged in a longitudinal direction of the abdomen, has one end thereof fixed in the vicinity of the abdomen of the dummy, and a plurality of gauges are arranged in a longitudinal direction of the band for detecting a bending strain of the abdomen when an obstacle collides with the abdomen. A measuring device measures time history of the bending strain based on bending strain of the respective portions of the band detected by the gauges arranged on the band, as a time transition of the bending strain of respective portions of the band.

A tire uniformity measuring apparatus having: a drum for rotating a tire; an oscillating member disposed parallel to a drum rotating shaft and pivotally supported on a machine base through a fulcrum; a movable member disposed in parallel to the drum rotating shaft in the plane including the drum rotating shaft and a tire rotating shaft, the movable member being laterally movable in response to a load acting on the tire in a lateral direction perpendicular to the radial direction of the tire; a load applying member for applying in advance a predetermined load to the tire; and a displacement detecting member for detecting as a displacement of the movable member the displacement of the tire rotating shaft which is dependent on variation in the lateral load; thereby detecting a variation in the lateral load of the tire. The apparatus may comprise a further movable member which is a shaft member constituting the fulcrum, the movable member being slidably movable along the longitudinal axis only in response to a variation in the tangential load, and a further displacement detecting member for detecting a displacement of the movable member, thereby detecting a variation in the tangential load acting on the tire.
