用传递矩阵法求解变截面钢板弹簧的固有频率

Determining inherent frequency of gradual rigidity leaf spring

利用梁的模型对变截面钢板弹簧的固有频率进行了计算 ,首先把连续的梁分段离散 ,得到各叶片的离散系统 ,再将各叶片组成的子系统合成 ,利用边界条件进行求解。文章给出了计算实例 ,通过与有限单元法的比较 ,说明该方法计算简便、精度高。

The matrix transfer in used to calculate,the inherent frequency of leaf spring with changing section is calculated with the beam model.The continuum beam is separated into many small beams,which can be composed as subsystem separately.A example is offered to show the precision of this method.Compared to the FEM method,this method shows simple and convenient.
