| dc.description.abstract | This study focuses on simulating and analyzing the stress distribution of various types of safety components used to secure elevator ropes, with the results recorded and later compared with actual experimental data. The research applies only to elevators from a specific manufacturer. For applications in different environments, the relevant data should be adjusted to fit the specific conditions and equipment.
The study is divided into two main parts: Based on tensile tests of steel ropes, the changes in force on the rope clamp were recorded. A 30Hz low-pass filter was used to convert the data into stress curves to identify the maximum stress points. The maximum stress was inferred to occur at the smallest diameter of the cone sleeve by analyzing three peak values.
Using professional 3D mechanical design software, engineering drawings were created as a foundation. Individual component drawings were developed based on these engineering drawings. Features such as layered stretching, fillers, and boundary conditions were used to accurately replicate the assembly of the rope clamp components. During the simulation of the tensile test using the software, two main issues frequently arose: incomplete simulations due to variations in boundary conditions and problems with uneven force distribution and displacement errors.Finally, based on the simulation results, the stress distribution and cost differences among four types of cone sleeves were evaluated.
This study centers on elevator rope clamps, systematically exploring the differences in stress distribution and performance across various designs through experimental and simulation methods. The results showed that in terms of maximum stress, the welded type and non-welded wrap-around type performed worse, increasing stress by 12% and 1.6%, respectively. However, the improved wrap-around cone sleeve showed clear advantages, with a 1% optimization in stress distribution and a 65% reduction in manufacturing cost, offering a viable alternative to the traditional welded design. This study not only verifies the feasibility of the improved design but also highlights the crucial role of simulation analysis in enhancing the safety and efficiency of rope clamps. | en_US |
