Optimization for transmission of tracked load-carrier/prime mover MT-LB by weight: the system of constraints and the sequence of their verification

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. Optimization objective function by weight was built, which is quite correct transmission models. It takes into account the geometry, dimensions, weight and strength properties of the main parts and aggregates. Variables planning are defined, which selected as basic geometric parameters of gearings: modules and number of teeth. A system of constraints on design variables was constructed, a technique for dynamically changing the constraints on the teeth number for gearbox was proposed. Also, a sequence of constraint checking is proposed, which will reduce the amount and time of calculations to find the best solution.
