The impression cylinder of J2108 offset press is regarded as research object in paper,and the deflection of cylinder is researched as simply supported beam with variable cross section .

以J2108型胶印机压印滚筒为研究对象,将滚筒挠曲变形作为变截面简支梁问题来研究,考虑重力载荷影响,通过积分法得到滚筒在印刷压力和重力载荷作用下的挠曲变形方程和曲线,应用MATLAB7.0平台上编写了印刷滚筒挠曲变形计算程序,为滚筒结构的合理设计提供了依据。

Introduced is a kind of space uniform rational spline curve, which possesses tension parameters and is based on hyperbolic spline functions.

引入了基于双曲样条函数的、具有张力参数的空间有理等距节点样条参数曲线,给出了这种曲线在每个样条子区间上为挠曲线段的充分必要条件;分析了这种挠曲线段没有尖点、重结点和泛拐点的特性;因而在用于空间曲线几何造型时可避免奇异性。

The curve continual steel box Liang shearing force stagnates the effect finite element analysis box section Liang has the big flexural rigidity and torsional stiffness, the stress performance good, spanning ability big, on the bridge the field of vision open and so on the merits, is in the bridge design the commonly used structural style, when receives under the dead load or the symmetrical live load function winding, because the lifting surface detrusion causes its bending stress to present the non-uniform distribution condition along the Liang width direction, this phenomenon is called "the shearing force to stagnate the effect".

曲线连续钢箱梁剪力滞效应的有限元分析箱形截面梁具有较大的抗弯刚度和抗扭刚度、受力性能好、跨越能力大、桥上视野开阔等优点,是桥梁设计中常用的结构形式,在受恒载或对称活荷载作用下挠曲时,由于翼板的剪切变形致使其弯曲应力沿梁宽度方向呈现不均匀分布状态,此现象称为&剪力滞效应&。
