摘要
讨论了工字形截面外伸梁在自由端受中力作用时的侧向屈曲问题,从理论上推导了其侧向屈曲的临界载荷,并同时用能量法给出了近似计算公式.认为外伸梁可以分解为简支梁和悬臂梁,当其一部分发生屈曲时,临界载荷为两者中较小者;当整个梁发生屈曲时,临界载荷为两者中较大者.
The lateral buckling of S-shape overhanging beam is discussed. The critical buckling load formula is derived by using two methods—theory analysis and energy approximate methods, and the two methods give the same results. The overhanging beam can be devided into a pin-ended beam and a cantilever beam, and the critical value of overhanging beam equal to smaller one between two beams. The result of this paper can be used in design of mechanical equipment and engineering structure.
