Fiber-optic scanner using this head is realized on the basis of existing computer printers and plotters andits characteristics are investigated. Fiber-optic technique is used for excitation of photon echo. Photon echo was observed with multimode fiber when it was coupled with initial pulsed laser radiation in quasi-singlemode regime. Predictions are made for the possibility of creation photon-echo fiber-based echo-processors and their possible schemes are proposed.

Expressions are obtained for the generalized driving force attributed to relative rotation angle and for the analogs of rod displacement and rod velocity related them with the angle and angular velocity of links relative rotation. The vector-matrix form of these expressions facilitates there using in algorithms of automatic formation multilink mechanism dynamics equations. In the mathematical model of hydraulic subsystem balance equations of working fl uid fl ow in view of its volume compression are used. Each one of them gives one fi rst order differential equation for each chamber of the actuator. The results of the numerical implementation of the proposed description are presented for planar three-link mechanism driven by three valve-controlled hydraulic cylinders.

Sensors consist of a glass or quartz monoblock to one end of which the input and output fibers are joined and on the other end is located a replica of a concave diffraction grating with a groove geometry ensuring minimal energy losses. The principal novelty of the offered sensors is the usage of such a grating-block allowing us to combine collimating, dispersing and focusing properties necessary for a spectra analysis in a single optical element.

The coefficients of the quadratic form, expressing the kinetic energy are represented as linear combinations of the seven independent trigonometric functions of generalized coordinates. The resulting system of differential equations of the dynamics is integrated numerically by the method Runge-Kutta in MathcadДля описания динамики плоского шарнирного механизма использованы уравнения Лагранжа второго рода. Коэффициенты квадратичной формы, выражающей кинетическую энергию, представляются в виде линейных комбинаций семи независимых тригонометрических функций обобщенных координат - базисных функций. Полученная система дифференциальных уравнений динамики интегрируется численно методом Рунге-Кутта в среде Mathcad

Векторно-матричная форма этих выражений облегчает их использование в алгоритмах автоматического формирования уравнений динамики многозвенных механизмов. В математической модели гидравлической части привода использованы уравнения баланса расходов рабочей жидкости с учетом её объемного сжатия, которые дают по одному дифференциальному уравнению первого порядка для каждой полости двигателя. Представлены результаты численной реализации предлагаемого описания для плоского трехзвенного механизма, приводимого в движение тремя гидроцилиндрами с дроссельным программным управлением

However, unsteady working conditions, such as frequent starts and stops of engines, changes in temperatures and etc., require the adjustment of the frequency of maintenance. In this situation, it becomes necessary to carry out maintenance of equipment at decrease in its performance, which is largely influenced by the state of lubricating fluids. The change in their properties determines both the current state of the unit and the possible deterioration associated with the accidental ingress of contaminants into the lubricant. The purpose of the study is to intensify the use of modern information technologies in the repairs and operation of machinery through rapid assessment of changes in the quality of liquid lubricants. The developed original design of the universal sensor for quality control of lubricants allows applying it in existing units of vehicles without additional modernization. The scheme of the proposed design differs from the one of similar devices in the ability to work with industrial, motor, transmission oils and hydraulic fluid. The performed calculations and the full-scale experiment proved the operability of the proposed device. In the course of the research, the operating temperature range of the lubricating fluid was determined for the most effective diagnostics; generalized data were obtained allowing deriving the dependencies of the sensor design parameters on the temperature of the lubricant. In further research to improve the safety of the device and prevent the deterioration of the lubricating fluid in the course of incorrect operation, it is planned to improve the developed product for monitoring and informing the operator about the current state of the lubrication system, taking into account changes in operating conditions of machines and equipment.

It is known that the shortcomings of the existing planting and sowing machines lead to considerable crop losses (uneven germination and weakened plants due to incomplete use of soil potential) and, as a consequence, losses of expensive planting materials. It is also known that the existing equipment and techniques cannot reduce the number of field vehicle movements, which leads to excessive compaction of the soil, a deterioration of its microstructure, and a decrease in fertility, as well as additional financial costs. To solve the existing problems of planting, a new technique is proposed. It is implemented on the basis of a pre-distributed planting material on a specially prepared tape. Such a technical solution allows sowing expensive planting material by the piece and in a strictly distributed sequence and, as a result, minimizing losses and ensuring a uniform depth of planting. The design of the sowing equipment is simplified and the adjusting works, as well as the cost of labour, are reduced. To confirm the theoretical assumptions, we developed a laboratory plant, and this paper presents the results of experimental work, which confirms high technological capabilities of the proposed equipment in terms of homogeneity of the seeding depth and its constructive simplicity. The presented technique based on the specially prepared tape material allows carrying out simultaneously both planting and additional agrotechnical measures, such as pointby-point application of a dosed fertilizer, which leads to an increase in the ecological compatibility of products, simultaneous soil cultivation with herbicides, etc.
