본 논문은 엘리베이터의 미끄럼이나 과속을 방지할 수 있는 보조 제동장치인 로프 브레이크에 관한 것으로 제동시 반력의 최대 영역 즉, 취약 부분(weak point)으로 예상되어지는 하우징 영역의 보강형상을 위치와 높이를 변화시켜서 구조해석을 수행하여 최대응력과 최대변형률을 비교 분석하여 하우징의 안전성을 검토한 후, 최적형상의 하우징을 적용시킨 로프 브레이크의 설치 각도에 따른 구조해석을 수행하여 구조적 타당성을 검토하고자 한다.

Hydraulic systems of rope brake for elevators are modelled to evaluate design parameters such as cylinder pressure, pis-ton displacement, accumulator capacity, and so on. To assure the results, experiments were performed. The analysis results agree well with the experimental results. The scheme in this study is expected to be utilized in the design of rope brake system for elevators to get design parameters and to improve the safety.

The objective of this study is structural analysis of rope brake for elevator. The finite element model was developed to compute the stress, strain and friction force for rope brake. The ANSYS code was used for this analysis. In order to structural analysis of rope brake, many variables such as internal pressure, boundary condition, load condition and constraints were considered.

In this study, hydraulic systems of the rope brake system of an elevator are modeled to evaluate design parameters that consider friction characteristics such as cylinder pressure, piston displacement, and flow rate. Hydraulic systems of the rope brake system are analyzed using the commercial program AMESim. Analysis modeling data are compared with data obtained from experiments, and the analysis modeling results are found to be reliable. The analysis results will be used to design hydraulic systems of the rope brake system of elevators.

The objective of this study is structural analysis and optimum shape of rope brake. The finite element model was implemented to compute the stress, strain and friction force for rope brake. The ANSYS code was used for this analysis. Structural analysis are effected by position and height of reinforcement figure. The structural safety was examined by an establishment angle of the rope brakes which made apply to housing of the most suitable shape. The optimum shape of the rope brake was decided after stress and strain results were compared and examined.
