Abstract
Hydraulic hoses are one of the major mechanical components that is used as power transmission. The hydraulic hoses, which is mainly used to transmit some power through oil pressure, are difficult to design the path and analyze the stress. In the view of designing the path, Hydraulic hoses are difficult to design the centerline curve in CAD system because they have high flexibility compared to the metal, which as treated as rigid body in CAD system. This is due to the fact that setting the exact location of control points on center lines is hard task. In the view of analyzing the stress, it is almost impossible to measure the stress on hoses with strain-gauge, which is frequently used to measure the local stress of metal. Strain-gauges on hydraulic hoses are subject to be destructed due to the high value of strain on hoses compared to those of metal products. These are the main reasons why the designing the path and analyzing stress on hoses are dependent on some computer simulation method. There are two ways to simulate the Rod-like structure such as hydraulic hoses. First one is to use the software based on the Cosserat Rod Model, and the second one is to utilize the software based on the multi-body dynamics CAE. In this thesis, a comparison study is conducted between the two methods mentioned above so that presenting a useful, referable guide-line is major purpose of this thesis.
