液压支架新型抗冲单元的拓扑设计及耐撞性研究
Study on Topology Design and Crashworthiness of Novel Anti-impact Units for Hydraulic Supports
摘要
Abstract
In order to improve the anti-impact of hydraulic supports,based on the characteristics of non-dimensional parameters governing the crashworthiness of thin-walled structures proposed by authors,a new type of anti-impact unit,namely the window multi-celled structures(WMCS),was designed by adopting bi-tubular and mixed multi-celled structures.The crashworthiness of anti-impact units with differ-ent cross-sectional shapes was systematically investigated by using a combination of experimental tests,simulation analysis and theoretical prediction.The results show that the inner and outer contours of the bi-tubular structures and the number of cells affect the deformation modes of the anti-impact units.As the in-crease of wall thickness,the energy absorption and initial peak crushing forces of the anti-impact units in-crease,among which the initial peak crushing forces are highly sensitive.Differently,the specific energy absorption and crushing forces efficiency increase first and then decrease.According to the optimal intersec-tion among deformation modes,force-displacement curves and crashworthiness,the WMCS-C1 with a wall thickness of 5 mm was selected as the anti-impact unit.关键词
