Abstract

Abstract:

Objective: A triangular crawler wheel system was designed for log skidders in place of the traditional tire, in order to improve the trafficability and to increase the tractive force and climbing ability of the vehicle. Methods: The technology solution, with the starting point of modifying the basic parameters of wheeled skidders to better adapt to the working conditions, selected the key parameters of the triangular pedrail wheel through the analysis of its structure composition and layout characteristics. Overall, the main parameters were theoretically calculated and determined by combining the driving theory, working efficiency and spatial layout relation, etc. More specifically, a mathematical model of the key parameters was established by introducing the driving efficiency theory on triangular crawler wheel system. Besides, a function for nonlinear constrained optimization, fmincon was implemented to obtain the optimal combination of the parameters, with the calculation achieved by MATLAB optimization toolbox. Results: Exitflag=1 is obtained from the output calculation results, indicating that the first-order optimality condition of this optimization meets the allowable range, and the analysis results are relatively ideal. According to the optimization results, the geometric layout plan of the triangular track wheel is drawn. In the layout plan, there is no interference between each part of the triangular track wheel. Conclusion: 1) Through the analysis of the composition and function of the triangular track wheel, combined with the working conditions in the forest, the overall arrangement scheme of the triangular track wheel suitable for the material gathering machine is proposed. 2) The key parameters of triangular track wheel were proposed, and the selection principles and methods of key parameters based on the practical investigation and comprehensive consideration of work efficiency, running stability and structural characteristics of triangular track wheel were determined. 3) Based on triangular crawler drive efficiency of the optimal principle, the crawler drive section of the drive power loss was analyzed. A mathematic model of the track driving efficiency was established to optimize the objective function, and with the help of MATLAB software in the optimization module, the key parameters for triangular pedrail wheel is optimized and the key optimized parameter values were finally obtained.

Key words: triangular pedrail wheel system, driving theory, work efficiency, key parameters, the optimization design
