METHOD FOR ANALYZING RIGIDITY IN STRUCTURE BODY

PROBLEM TO BE SOLVED: To provide a method for analyzing rigidity in a structure body, which shortens time to be required for analysis without taking labor and time in analysis. SOLUTION: First, in a subroutine 100, an on-orbit contact coordinate displacement amount 40 is determined based on an initial value, and an elastic approach amount 41 is obtained based on the on-orbit contact coordinate displacement amount 40. Then, a rolling element load 42 is obtained, and contact reaction force 43 is subsequently obtained. Further, an element Jacobian matrix 44 is obtained. A whole deformation is solved by using a versatile function, based on the element Jacobian matrix 44, and the on-orbit contact coordinate displacement amount 40 is determined again, based on the solution of the whole displacement. The procedures are repeated till the on-orbit contact coordinate displacement amount 40 converges. COPYRIGHT: (C)2010,JPO&INPIT
