【摘要】 该文从材料力学和塑性力学角度分析了法兰长杆件摆辗时的塑性稳定条件,首次指出摆辗件侧面形状为近似双曲面形状,该形状造成长杆失稳与一般杆件失稳不同,由此提出两点防止失稳的建议供参考试用。更多还原

【Abstract】 This paper is an analysis to conditions of plastic stability of flange-long-rod part in respect of material mechanics and plastic mechanics;the author initially indicates that the flanks of the part being processed are in the shape of hyperboloid,which makes the stability loss of the long rod different from that of common rod,the author thereby comes up with two recommendations for reference.更多还原
