Title:
AUTOMOBILE CENTER PILLAR AND METHOD FOR EVALUATING PERFORMANCE OF UPPER PART BUCKLING PROPERTY PROOF OF AUTOMOBILE CENTER PILLAR
Document Type and Number:
Japanese Patent JP2006281964
Kind Code:
A
Abstract:

To provide an automobile center pillar capable of preventing V-shaped bending buckling in a center pillar upper part at the time of a side collision.

A molded product suction and take-out capturing device has strength balance of an upper part and a lower part having ≥0.5k(N×m) in absolute value of a difference M1-M2 of each maximum value between buckling limit cross-sectional moment M1 of the center pillar upper part 1a at the time of a falling weight collision to the center pillar upper part 1a determined by performing a dynamic collapse test analysis by a dynamic explicit method using a model for finite element solution analysis for a center pillar structure and cross-sectional moment M2 in the vicinity of a buckling position of the center pillar upper part at the time of a falling weight collision to a center pillar lower part 1b.
