Abstract

Wheel loaders are utilized not only on construction sites, but also for general purposes, such as manufacturing and transportation. Therefore, during the basic design stage of this type of working device equipment, the designer should consider specifications as well as working performance. In this research, a characteristic analysis program was developed for use in the basic design stage of construction equipment using multibody dynamics analysis. In addition, through the optimization of its links, improvements to the lifting capability of a Z-bar-linkage-type wheel loader were suggested. Using the developed program and process, it is possible to reduce the time required for the basic design of the working device.

휠로더는 건설 현장뿐만 아니라 운반, 제조업에도 다양한 용도로 범용적으로 활용된다. 따라서 작업장치 기본 설계 시에는 작업성능뿐만 아니라 버켓의 각도변화 등 작업사양을 만족시키는 설계 안을 도출 해야 한다. 본 연구에서는 다물체 동역학 해석을 통하여 휠로더 작업장치 특성 분석 프로그램을 개발하여 작업장치 기본설계 시 활용할 수 있도록 하였다. 또한 본 프로그램과 최적설계 프로그램의 연동을 통해서 Z-bar 타입 휠로더 작업장치의 작업사양을 개선하였다. 개발된 프로그램을 활용하여 작업장치 설계 시 작업장치 컨셉에 따른 기본설계방안을 도출하는데 소요되는 시간을 절감할 수 있을 것이다.
