摘要
本文根据拉弯杆件轴线挠曲时的微分方程,导出了在各种常见荷载如集中力偶、集中力及均匀分布、三角形分布或抛物线分布荷载作用下,计算杆件各截面的挠度、转角、弯矩及剪力的初值方程及其通式。同时,还导出了各影响函数的计算公式。
According to the differential equation of the flexwal deflections of a straight bar under simultaneous axial tensile and transverse loading such as concentrated moment, concentrated force and uniformly, triangularly or parabolicly distributed loading, a general form of the initial value equation for the deflection, rotation, bending moment and shearing force in any section of the bar was developed in this paper. In addition, the formulas of the influence coefficients were worked out.
