Scientific and methodological apparatus for substantiating requirements for planetary rovers wheels design parameters and operating modes
Abstract
The article considers methods, algorithms and models that make it possible to form a reasonable choice of design parameters and operating modes of the wheeled propellers of the planetary rover chassis to increase cross-country ability and mobility when moving on loosely connected ground in conditions of reduced gravity. The analysis of the operation of planetary rovers on the surface of Mars, as well as the results of ground-based experimental testing of the landing gear and wheeled propellers of planetary rovers in imitation of reduced gravity, is presented. Based on the results of experimental studies, the reasons for the decrease in the adhesion of the wheeled propellers of planetary rovers with loosely bonded soil in conditions of reduced gravity are described. Models and an algorithm for selecting the design parameters of the ground hooks of wheel thrusters to increase the adhesion of the wheel thrusters of the planetoid when moving on loosely connected ground are presented. Models and a law for controlling the distribution of power supplied to the wheeled propellers of the planetary rover chassis when moving on loosely connected ground in conditions of reduced gravity have been developed. The results presented in this paper make it possible to increase the patency and mobility of the landing gear of planetary rovers when moving in conditions of loosely bonded soil and low gravity.
