Title:
内燃機関のコネクティングロッド設計方法
Document Type and Number:
Japanese Patent JP4517731
Kind Code:
B2
Abstract:
An internal combustion engine connecting rod (1) is designed with bolts (4) having a minimum required strength. A strength safety factor Sfa is calculated based on an axial strength limit load F X of the bolts (4) and the maximum load F B to be born by the bolts (4) due to a piston inertia force (Sfa = F X /F B ) acting on the connecting rod (1). A mating surface separation safety factor Sfb is calculated based on the tensile load (F B - F C ) resulting from the piston inertia force and the load F E carried by the bolts at a mating surface separation limit, i.e., the maximum bolt load F E at which the connecting rod main body (2) and the cap (3) remain in contact without separating (Sfb = F E /(F B - F C )). The mating surface separation safety factor Sfb of the connecting rod (1) is set to be equal to or larger than the strength safety factor Sfa of the bolts (Sfb ¥ Sfa).
