| 摘要: | 本文利用最小位能原理推導受分佈力作用之預扭Timoshenko樑的靜態彎曲方程式。並求出一懸臂預扭樑受分怖力時彎曲變形的正解。文中探討扭角、厚度比及剪力變形對預扭樑之靜態彎曲特性的影響。
Static bending of a twisted beam subjected to distributed transverse loads is established by using the Timoshenko beam theory and applying the principle of minimum potential energy. The closed-form solution for the static deflection of cantilever twisted beam is then derived. The effects of the twist angle, thickness ratio and shear deformation on the static bending characteristics of twist beams are investigated and discussed. |
