Research on Multiple Regression and Fitting Technology of Dynamic Opening Simulation Data of Life-Saving Parachute

Aiming at the problem that the reference value of life-saving parachute dynamic simulation data is uncertain, a method of multivariate nonlinear regression and fitting technology for the dynamic parachute opening simulation data of the parachute is proposed. By accumulating a certain amount of simulation data, the corresponding simulation result data is taken as the analysis sample. And through multiple regression, the relationship between the parachute resistance characteristics and each parameter and time in the parameter dimension and time dimension is obtained. The fitting state of the resistance characteristics in the time dimension can be intuitively seen through the fitting technology of the resistance characteristics obtained from the simulation data and the correlation relationship, which shows the effectiveness of the method. The method can significantly improve the reference value of the test results of the parachute dynamic parachute opening simulation test, which proves the practicability of the method.
