PURPOSE:To obtain the solution of a hyperbolic type equation as a practically very satisfactory approximate solution by giving a function value as the solution of the hyperbolic type equation and is deviation with respect to two variables and performing numerical analysis of the physical quantity by interpolation dependent upon a cubic polynomial consisting of the distance from one of these two variables to a variable intermediate between them. CONSTITUTION:The function as the solution of the hyperbolic type equation and its differential calculus exist, and two variables sufficiently close to each other and a variable intermediate between them are set; and when values of the function for two variables and their deviations are given, the value of the function for the intermediate variable is interpolated by the cubic polynomial consisting of the preceding given function value, its deviation, and the distance between one of two variables and the intermediate variable. Thus, numerical analysis of the physical quantity which has a high degree of satisfaction and supplies sufficient data for production of an actual machine is realized by numerical simulation using a computer without actually executing the expensive analytic experiment of the physical quantity which takes a long time. |
