MOTION LOCUS ANALYZING METHOD AND MOTION LOCUS ANALYZER

摘要

PPROBLEM TO BE SOLVED: To provide an analyzing method used in motion locus analysis which method prevents the production of an unnatural analysis result of an object's bouncing back in an incoming direction after collision. PSOLUTION: According to a method of analyzing the locus of an object in motion involving repeated collisions with a plane, an information processor 1 analyzes the locus using a contact model such that a spring and a dashpot are arranged in a normal direction and also in a tangent direction to a contact point. A control means 11 of the information processor 1 stores an attenuation constant of the dashpot arranged in the tangent direction in a memory means 21, the attenuation constant being determined so that the speed of the object in motion in the tangent direction at the point in time of its coming in contact with the contact point and then returning to a noncontact state is positive. This attenuation constant is read out of the memory means 21, and the motion locus of the object in motion involving repeated collisions with the plane is analyzed using the read attenuation constant.
