摘要
曲梁在机械工程中的应用非常广泛,例如吊钩、链环等,因此对曲梁进行力学分析和变形计算是机械设计的重要内容。采用传递函数方法对复杂曲梁进行分析,根据曲梁上的载荷和曲线的形状将曲梁分成不同的单元,建立单元的分布传递函数求解模型,并在单元之间连接处作了特殊处理,通过坐标变换后再组集成梁整体平衡方程。算例表明,此方法具有很高的精确度。
The application of curved beam in mechanical engineering is very popular,so the mechanics analysis and displacement computation of curved beam are important work for mechanical design.The transfer function method is used to analyse the complex curved beam.The curved beam is divided into different unit according to the outside forces and the shape of curve,and then the transfer function method solution of the unit has been built.Special treatment has been put in practice for unites connection.The system equilibrium equations are given after the coordinate transformation.The example show that it method has the characteristics of high precision.
