Abstract

In the recent years, it is important to evaluate the durability and the reliability of the vehicle, aircraft, and structure. Especially, in case of the vehicle, the durability and reliability are tested by driving test after making prototype vehicles. However, these methods require many costs and efforts for the experiment are needed to react the defects of product. This problems can be settled by simulator which supplies the realistic environments. In this parer, four-axial road simulator with hydraulic power and driving program to operate are made up. The displacement road profile is realized by accelerometers. For the verification the real-vehicle experiment is executed and road profile obtained from the experiment is verified by four-axial road simulator.

차량이나 항공기를 개발하는데 있어서 성능과 내구성에 대한 실험은 필수 과정이지만, 이를 위해서는 많은 개발 비용과 시간이 소요되므로 그 대체 방법으로 시뮬레이터를 이용한 실험이 보편화 되고 있다. 특히 노면의 경우 시뮬레이터에 사용할 변위 데이터를 정량화하기 어렵기 때문에 가속도계를 이용하여 노면 데이터를 습득하는 것이 일반적이다. 본 연구에서는 가속도계를 이용하여 습득한 가속도 신호를 변위 신호로 변환하기 위한 소프트웨어를 개발하여 시뮬레이터에 사용되는 변위신호를 생성하였고 이를 토대로 4축 시뮬레이터를 이용한 실험을 통하여 그 타당성을 검증하였다.
