Abstract
The disclosure aims to provide a structural member made of an extruded material that effectively helps to reduce weight while ensuring strength and rigidity. The structural member has a varied wall thickness along an extrusion direction.
Claims3
A structural member made of an extruded material, wherein the structural member has a varied wall thickness in a height direction along an extrusion direction,
- assuming that a position in the extrusion direction is represented by an X-coordinate, and that a product allowable stress is σa, a section modulus is Z(x), a cross-sectional area is A(x) and a generated bending moment is M(x) at a given part x, the wall thickness of the structural member is thickest at a center position in the extrusion direction where the bending moment M(x) is largest while minimizing the cross-sectional area A(x) when the section modulus obtained by a formula:
- Z(x)=M(x)/σa is varied according to a position of the part x.
