中文说明:应用背景 插值法中的牛顿插值,提出了一种简单、实用的凸轮工作廓线的修正设计方法,这种方法不必对原有的解析方程进行修改计算,只需通过对要进行修正的曲线附近的一些离散点的数据进行处理,就能对现有凸轮工作廓线进行修正,特别适合凸轮曲线在实际使用中的局部修正设计。关键技术 设法根据表格中已有的函数值来构造一个简单的函数f(x)作为f(x)的近似表达式,然后再用f(x)来计算新的点上的函数值作为f(x)的近似值。通常可以选用多项式函数作为近似函数f(x),因为多项式具有各阶的导数,求值比较方便。用代数多项式作为工具研究插值问题,通常称为代数插值。
English Description:
Application background interpolation method, a simple and practical method to modify the cam profile is proposed. The method is not necessary to modify the original analytical equation. It can be used to modify the existing cam profile.Key Technology try to construct a simple function f (x) as an approximate expression of F (x), and then use f (x) to calculate the function value of the new point as the approximate value of F (x). Usually can use polynomial function is used to approximate the function f (x), because each order derivative of polynomials have evaluated more convenient. Using algebraic polynomials as a tool to study the interpolation problem, usually referred to as algebraic interpolation.
