碩士 === 元智大學 === 機械工程學系 === 106 === All elevator car and structure of machine-room designs in Taiwan are based on regulations of the Chinese National Standards(CNS).However, there is no relevant laws and regulations as the reference for the structure design method of the counter-weight side, resulting in the diversification and the safety factor has insufficient (resulting in safety problems) or too high (waste of costs) concerns.Most of the Counterweight structure fixed by welding method, which is not flexible for it’s weight and size. For the past few years, welding fumes has become the biggest and most controversial environmental issue of our life. Some elevator manufacturers have improved its structure by changed the way of fixing the counter-weight frame to bolting, in order to meet environmental requirement.For three types of counter-weight frames with the traction ratio of 「1: 1」, and the elevator’s capacity which is 12 and 15 people are used to analyze in this dissertation. By using SolidWorks Simulation software to analyze of stress on each type of counter-weight frame at static maximum loading, from the simulation results and consider structure safety, reliability, the cost and management, the use of bending-combination type as the basis for the design of counter-weight frame. Then by the dynamic loading analysis of elevator operation, the static analysis results are compared to explore the convergence and the correctness of the dynamic analysis results, and analyze the stress generation region, in order to explore the optimization possibility of the bending-combined structure.
