Визначення динамічних load factors в links of two-drum drive of suspended cable timbertransporting plant equipped with electric motor and elastic coupling, using the transient electromechanical processes in drive motor, variable moments of inertia driv d Зміни в коефіцієнтах longitudinal rigidity moving cables. Методологія. Розроблений динамічний model drive contains number of theoretical dependencies, calculation schemes and systems differential equations that describe the dynamic processes in the 2-drum electromechanical drive of suspended cable timbertransporting plant. Різні еквівалії електромагнітного стану машини, які описують transient processes в drive motor, є основою на Park-Goriev equations. Різні еквівалії механічної частини drive motion є розроблені на основі D'Alembert's метод. Для numerical integration differential equations systems, modified Euler's method is used. Findings. The simulation model calculates dynamic forces that are active in mechanical gears and the drive coupling; потенційно небезпечні операційні режими drive of suspended cable are determined. Залежність від load dynamic factor на структурних параметрах drive is established. Вплив length of free part of movable cable на magnitude of dynamic loads в drive is investigated. Originality. Для першої години, динамічний model drive of suspended cable timbertransporting plant was proposed which takes into account: transitional electromechanical processes в drive motor; variable inertia moments of drive drums; variable load acting on drive drums at each of stages of the technological cycle of the cable plant work. Визначення моменту inertia of drive drum and moment of technological resistance that are variable in time are made taking into account the multilayer winding of cable on the drive drum, as well as forces of elastic deformation of moving cables. Practical value. Нові методи, algoritmy і програми мають бути розвинені і існуючі ones повинні бути спрямовані на розрахунок динамічних навантажень в шинах і передачах електромеханічного керування кабельною площею з пов'язаними і перехідними cables. На основі основи стійких dependance of load dynamic factor, recomendations for choice of structural and operational parameters of drives of thes plants were developed.

Permanent forest roads (with сrushed stone and gravel road surface) form approximately 8… 10% of the total operational length of roads.

It was identified that at this moment, a selection of methods is used for measuring the radii of horizontal curved sections of roads, which have certain advantages and disadvantages in specific natural production conditions. For calculating the radius of curvature for auto forest road projects it is recommended to apply the method of measured angles by chord angle deviation, which is sufficiently accurate for engineering purposes and does not require the usage of special high-precision equipment and tools.

The transportation of crushed material in such systems is carried out due to the air flow. In the woodworking industry, there are technological processes that are often accompanied by the formation of dust and other small air pollutants. Studying the movement of particles in polluted air makes it possible to transport or separate such particles, while spending less energy. The mathematical model of the movement of dusty air containing separate solid particles (production waste) was worked out, and based on it solution will allow separating and capturing crushed wood particles and reducing the cost of consumed electricity for transportation.
