The theoretical analysis of dynamic phenomena in transmission tracked forest machine is much more difficult in the absence of experimental data on the effects of the input characteristic of the machine. The most characteristic species in the transmission effects that arise under real operating conditions allow to evaluate the results of experimental studies, they also provide an opportunity to assess the quality of theoretical studies. To determine the loading of the transmission in the experiment involves the measurement of a number of kinematic and power parameters characterizing the speed and stress state of the transmission. In the course of the research used a special measuring equipment made in Germany includes the high-speed digital telemetry system for strain "TEL1-PCM-HS" company KMT. This article describes how to determine the dynamic load transmission elements tracked forest machine LZ-5 in overcoming individual barriers in experimental studies (tests). The paper presents a program of pilot studies tracked forest machine. Presented curves change the time settings on the final drives and cardan shaft, depending on the speed of the engine and drive sprockets in overcoming obstacles GLZM with different gears. histograms were constructed on the distribution of the torque transmission shafts for various modes of overcoming obstacles in order to analyze the influence of operational factors on the magnitude of dynamic loads. The article presents the distribution curve of the moments on the driven shaft final drive to overcome obstacles tracked forest machine with a pack assortments in the volume of 12m3. It was noted that there are no less than 20 times the dynamic point values, which exceed the estimated time for the overcoming of obstacles. From the studies that the transmission level of at least dynamic forces having height obstacles.

The article presents the program and methodology for conducting experimental studies of the dynamics of the tracked movement of loading and transport machines in the applied program package "Universal mechanism" using module "tracked vehicles". Presents the objectives of the auxiliary and the main dynamic experiments. Auxiliary experiments serve the purpose of calculation of determining the initial state of tracked loading and transport machines and training perform basic experiments. The main experiments designed to study the dynamic properties of the tracked loading-transport machines. The list of dynamic experiments including experiments on: equilibrium; the tension of the caterpillars; the calculation of initial velocities; the vertical pumping; the linear progression; the control without feedback; tests with the operator (driver). The article describes the steps which are needed to prepare a simulation model of the crawler handling machine before performing dynamic experiments. Examples are given of the parameters of the irregularities and white-the path on which will move the simulation model tracked the loading and transport machines during the experiments. Presents fragments model the motion of a tracked loading-transport machines. The proposed program and methodology for conducting experimental research, tracked loading and transport machines in the applied software package that allows the design stage to quickly conduct a number of virtual dynamic experiments with the aim of finding operating points, accelerations and loads in the various elements of the machine (primarily in the elements of cater-pillar tracks). This will make it possible in the course of virtual experiments to find the optimal parameters of construction elements tracked loading and transport machines at the design stage that will allow the prototype cars with the least modifications to work in the given natural-production conditions.
