ALGORITHM OF OPTIMAL DESIGN FOR TRANSMISSION OF TRACKED LOAD-CARRIER/PRIME MOVER MT-LB BY MASS

Abstract

Solving the problem of optimizing for transmission of light multipurpose tracked load-carrier/prime mover MT-LB is a perspective area of research because it improves the mass characteristics of the machine, to ensure the load capacity and durability of transmission at upgrading. A system of constraints on variables planning and the sequence of their verification in the order of growth of the estimated volume of computing is constructed. This allows you to significantly reduce the total settlement time. The applied methodology and detailed algorithm for optimal design of the transmission has been developed. They take into account the constructive, technical and technological features. They also allow to reduce the error of the calculations due to the error-control of the calculations of gear ratios and the equality of the axes distance for gearbox and additional reducer meshing's. The algorithm contains following ethics: the task of the input data; generation of an external LPτ-sequence; check the relevant constraints; checking the limit constraints on the inter-axes distances; calculation for the test point of gear ratios; determination of boundary numbers of teeth; generation of internal LPτ-sequence; check the relevant constraints; search for the best option; increase the accuracy of calculations; clarification of parameters; additional verification calculations.
