Abstract

Hydraulic hoses are used as pipelines for transferring power from hydraulic systems in various machineries such as construction equipments, automobiles, and aircraft. Hydraulic hoses protect the system from vibration or impacts, and they are being used to transfer energy in all segments of the industry. In order to protect the system from various external environmental conditions, hydraulic hose assemblies must be able to withstand a wide range of temperatures and pressures, as well as variations in other factors. In previous studies, an acceleration model for the hydraulic hose assembly was developed by taking into account only one of the acceleration factors (temperature or pressure). Therefore, the objective of this study is to develop a comprehensive acceleration model that takes both temperature and pressure into consideration.

유압호스는 건설기계, 자동차, 항공기 등 각종 기계의 유압장치에서 동력을 전달하기 위한 배관으로 사용된다. 산업의 전분야에서 에너지를 전달하기 위한 배관의 한 종류로서 진동이나 충격 등으로부터 시스템을 보호하는 역할을 한다. 여러 가지 외부 환경 조건으로부터 시스템을 유지하기 위해서는 호스 조립체에서 온도와 압력 등의 외부 환경 조건에 대한 내성을 가지고 있어야만 한다. 본 연구에서는 기존에 호스 조립체에 대해 온도 또는 압력 중 한 가지 인자를 고려한 가속모형을 제시한 연구는 있었지만 두 가지 인자를 동시에 고려한 가속모형은 제시하지는 못하였으므로, 호스 조립체의 압력과 온도를 모두 고려한 복합가속 모형식을 제안하는 것을 목적으로 한다.
