The perspective construction of the combined machine for forest fires suppression is presented. The recommendations for its application at prevention of forest fires and their elimination are developed

The algorithm for managing of supplying of fuel and lubricants, which takes into account the cost of delivery by vehicles and allows quickly determine the optimal batch size and type of vehicle for delivery to ensure the minimum cost for the purchase, storage and delivery of fuels and lubricants, is built. The algorithm can be used in management of subsidiary manufacturing companies - consumers of lubricants and primary production organizations - suppliers of fuel and lubricants to make decisions under varying modes of consumption and prices

Results of probes of systems recovery in suspenders of cars are presented. Designs of devices recovery energy for use in suspenders of cars which specify in their per-spective use in a direction of increase of efficiency of cars are developed and approved under operating condi-tions

The article introduces a study on the creation of a simulated physical and mathematical model of the working process of a strip thrower, throwing soil in a directed flow. The problem solved with the help of this work is aimed at optimizing the cutting and ejection process in a given direction of the soil with minimal energy consumption with a maximum emission range. The article describes a methodology for calculating the milling thrower, which is oriented to the formation of the required amount of soil to create a mineralized strip at the edge of a forest bottom fire. Improving and realizing the full reproduction of physical and mathematical models using process simulations, you can save resources on the development of forestry aggregates. The study presents a productive method of processing soil with milling cutters, which helps to reduce energy consumption due to the formation of oriented mineralized flows of soil. For a physical and mathematical description of the process, a simulation program has been compiled that allows you to test the specific task of minimizing energy consumption at a maximum distance of soil discharge with a constant flow density to the rotational speed of the milling throwers

The mathematical model of the process of giving and soil emission with the working tools of a combined soil-thrower is developed for optimization of various parameters of the developed assembly

In this article, the mathematical model of management of interaction of working body of the cutter with branches of trees is submitted. Optimization of design data of the machine for scrap of trees is executed

The article presents a mathematical model of the interaction of vibration control the working body of the roots carver with soil and plant roots to optimize the design parameters roots carver

The mathematical model of working unit co-operation of plant lifter with soil and roots of plants for optimization of plant lifter’s different parameters is developed

Analytical dependence, defining powers and moments influencing the working unit of lever breaker are shown, which allow determining the stubbing force necessary in adjustment for requirements for modes and parameters of work of lever breaker

The dependences of the distribution of stump roots, allowing to model stump parameters to assess the difficulties of stumping are given, in requirements justification for stumping equipment. Based on the analysis of lever breaker working process, the differential equation of lever motion is got, which connects the moments acting on it and breaker performance modes and allows to set the parameters and modes of lever breaker in stumping of various sizes and species of wood
