#### ABSTRACT

In this paper, the spatial analytic geometry problem is transformed into a plane analytic geometry problem by analyzing the trajectory of the feed tank.Then, the objective function is established to minimize the longitudinal distance of the relevant coordinates, and the genetic optimization algorithm is used to obtain the minimum longitudinal distance of the relevant coordinates.Finally, an ideal parabolic equation with an upward opening is obtained.The slope, the coordinates of the main cable point, the space paraboloid equation and the datum sphere equation are used to analyze the variation rule of the radial distance between the ideal paraboloid and the datum sphere.Exhaustive method using violence to 886 groups of data into the model, and the corresponding coordinates in the ideal paraboloid, finally will be ideal paraboloid and benchmark of the spherical coordinates in space, the distance between two points in the formula to find the ideal paraboloid and benchmark spherical coordinates of radial distance, equal to the scale of the various actuators.
