Time measurement device for rotationally symmetrical body, has control device controlling curvature of path curve of movable body whose fixed path consists of two edges, where one edge comprises area with curvature in horizontal plane

摘要

The measurement device has elongated cuboid bodies (1) mounted on a base (2) for forming a support structure for a rolling element (3). An energy supply device supplies necessary energy to a movable body for a periodical movement. A register device registers a number of periodical body movements within a determined time interval. A control device controls a vertical curvature of a path curve of the movable body, where the movable body rolls on a fixed path. The fixed path of the movable body consists of two edges, where one of the edges comprises an area with a curvature in a horizontal plane.
