LOAD TRANSMISSION ANALYSIS DEVICE FOR NONLINEAR STRUCTURE

摘要

PROBLEM TO BE SOLVED: To analyze load transmission of a part, where linear elastic deformation is dominant, of a passenger car body etc., which elastically deforms by a collision.;SOLUTION: Substitution means 1 substitutes a complete linear elastic body for a cabin part, where linear elastic deformation is dominant, of the passenger car body. Collision deformation calculation means 2 calculates collision deformation of the passenger car body after the substitution. Load condition setting means 3 finds load data on the linear elastic body part from deformation data on the linear elastic body part. Rigidity index calculation means 4 calculates deformation of the linear elastic body part by a finite element method on the basis of a rigidity matrix of the linear elastic body part to find rigidity indexes such as U^* and U^**, and stores them in rigidity index storage means 5. Load transmission calculation means 6 finds load transmission data from the rigidity indexes. Load transmission output means 7 outputs the load transmission data. Thus, the load transmission of the cabin part of the passenger car body which elastically deforms by a collision can be analyzed, and the analysis device is usable to improve a car body structure.;COPYRIGHT: (C)2013,JPO&INPIT
