中文摘要：

针对承受分布载荷作用下直梁型柔性构件的变形进行了分析,同时考虑大变形而带来的几何非线性问题,采用数值积分的方法对其变形进行求解,给出了计算末端角变形与末端位移的一般表达式。通过实例计算,并与有限元模拟结果进行对比,误差在3%左右,验证了该分析方法的有效性。

英文摘要：

The deflection problems of the flexible cantilever under distributed loads are analysed and the geometric nonlinearity with big deformation is considered, the integration method is used to solve the deflection of the flexible cantilever and the numerical integration formula is deduced to calculate both the anglar deformation and the displace- ment at the end point. Examples are performed and contrasted with the FEM results, the error is about 3% ,so it proves the validity of the anlysis method.
