McNamm Wheel AGV Design

Abstract

Nowadays, the development of intelligent manufacturing and industrial Internet technology is leading the trend of the times step by step, the development of intelligent equipment has gradually become the traditional manufacturing industry is facing the transformation and upgrading of an important strategic point. At present, AGV handling robots have been widely used in all walks of life, but the general wheeled robots on the market generally have some problems, that is, restricted by the environment, can not move flexibly in the narrow space, but the use of McNamm wheels can be a perfect solution to this problem, so based on the McNamm wheels of the wheeled trolleys have a broader application prospects. This design focuses on the study of a wheeled AGV based on McNamm wheels that can work flexibly in a small space. The main content of this design is to analyze the structural characteristics and working principle of the McNamm wheel AGV cart, master the common design steps of non-standard equipment, understand the positioning principle of wheeled robots, transmission scheme and trajectory control principle by consulting relevant information, design the transmission and control system of the McNamm wheel AGV cart according to the needs of intelligent inspection, logistics, transportation and distribution functions, and carry out the calculation of parameters of the main programs. Mainly through the McNamm wheel work force analysis, so as to determine the direction of its movement, and then through the combination of a number of wheat wheel to achieve the movement in all directions. Then through the load and body requirements on the spring design, and then in accordance with the spring requirements on the hydraulic cylinder for simple calculations, and finally through the solid works, proe, creo software on the mcnemonic wheel body modeling design, and then the use of mainstream simulation and analysis software ANSYS workbench, Adams on the simulation and analysis of the established model.
