排気システムにおける排気管同士を連結する球面継手の配置位置決定方法および排気システムの製造方法

Document Type and Number:

Japanese Patent JP6450166

Kind Code:

B2

Abstract:

Provided are a method for determining the disposition position of a spherical joint for coupling exhaust pipes to each other in an exhaust system, and an exhaust system, which enable engine vibrations to be more effectively damped. In the present invention, strain gauges are attached at a plurality of locations in an exhaust system (1), simulated vibrations which simulate engine vibrations are imparted to the upstream-side end of the exhaust system (1), and bending strain is measured at each strain gauge. On the basis of the bending strain measured at each strain gauge, detected is a position at which generated is a bending moment that is equal to or greater than or equal to a torque amount which generates a maximum static friction force between a spherical inner-circumferential surface (26) and a spherical outer-circumferential surface (27) of a spherical joint (2) which come into contact with each other, and the detected position is determined to be the disposition position for the spherical joint (2).
