Research of optimum design method with positive displacement motor linear

应用齿轮啮合理论原理,采用三次样条函数作为拟合曲线进行数值分析,得到离散的定子与转子共轭线型.以简单函数寻找解析解的方法为基础,扩散到以数值分析为基础寻找优化解的范围.将简单函数求解法与三次样条插值法进行比较,证明了优化方法的有效性与可行性.

The application of theory of gear meshing principle,using cubic spline function fitting curves,to the numerical analysis,the discrete conjugate linear of stator and rotor is obtained. Based on the simple function for analytical solution method,spreading to the base of the numerical analysis the range of optimized solution is obtained. Compared with the simple function solving method and cubic spline interpolation method,the effectiveness and feasibility of the optimization method are verified.
