摘要
根据广义位移计算的一般公式导出剪力对齿状简支梁挠曲变形影响的计算方法,根据对梁的齿数、齿形、齿高、高跨比及荷载类型等影响剪力与弯矩引起的变形比的主要因数之分析和与等截面矩形梁的比较,得出一个简便的计算方法和几条有用的结论.
In this paper, a calculation method of affections caused by shear forces to the flexure deformation of a simple supported toothed beam was carried out from the formula of general displacements calculating. The main factors which affect the ratio of the deformation caused by shear forces to that of by the moments of the beam were analyzed: the tooth number, the tooth shape, the tooth depth, the ratio of span to depth of the beam and the load-bearing types. The affections are compared with that of a simple supported rectangular beam, which have constant depth. As a result, a brief computational method and several useful conclusions are derived.
