Abstract
The purpose of the paper is to develop an effective shock absorber designed to reduce dynamic loads on the inclined hoist structure in an emergency involving a fall of a trolley from the inclined hoist, to determine the kinetic energy distribution of trolley contents and to substantiate the integrity and operability. The approach we propose for such substantiations is based on numerical methods employing structural material elastic-plastic behavior models. This approach allows one to obtain an accurate result without excessive conservatism and to predict in advance the reliability of the designed products with providing the optimized product metal content.
Presented in this paper is an impact analysis for an inclined hoist with the trolley that falls from the maximum possible lifting height to come into contact with an unmodified shock absorber, an iterative approach to optimize the shock absorber metal content and properties, and a comparative analysis of the results obtained in each case. The computational analysis was performed by the certified
ANSYS/LS-DYNA software package. With mathematical 3D modeling as a decisive factor, the implemented approach enabled a deep and detailed analysis of dynamic processes, shortened the design time and cut down the prime cost of the developed design through giving up costly full-size testing at the design optimization stage. The approaches employed in the paper cut down the prime cost of the developed design through shortening the time spent to develop the analysis-and-design documentation and through giving up interim full-size testing, which enabled us to get down to final testing with an optimized design in order to obtain a certificate.
