摘要
针对由铰链梁横向振动模型而建立的四阶微积分方程,提出紧差分格式进行求解,利用Newton型迭代法处理积分项,给出差分格式解的存在性、收敛性和稳定性的证明.数值结果表明:格式的精度为O(h4).
A compact difference scheme is proposed to solve the fourth-order integro-differential equation arising from the transverse vibrations of the hinge model. Newton type iteration methods are presented to deal with the integral term. The existence, convergence and stability of the scheme are also proved. Numerical results show that the accuracy order of the Scheme is of O(h4 ).
