Research of Oscillation Processes of a Mobile Lift Working Platform

Problem. The work is a continuation of research in the field of studying the regularities of the functioning of mobile lifts with working platforms (MLWP), determining the kinematic characteristics of the equipment during the execution of certain technological operations and their influence on oscillatory processes. Goal. The main goal of this work is to compare the results of research performed on computer models and on a full-scale model of the machine. Methodology. The purpose of this work was to develop a suitable computer model of MLWP and investigate the influence of the parameters of the mobile lift and the features of the machine's work process on the oscillatory processes, as well as to compare these results with experimental data obtained on bench equipment. One of the solved problems is the development of a computer model of MLWP, which allows to adequately simulate the load modes of the machine and conduct research on the influence of the operating modes on the oscillatory phenomena observed during the execution of technological processes. Results. Also, the developed model will be useful in determining the reach zones of the selected equipment during installation work in the time of construction or maintenance of buildings, when performing tasks in the communal economy, servicing infrastructure objects of road construction, etc. Originality. The paper proposes a possible way of researching the influence of the parameters of the mobile lift and the features of the management of the working equipment on the kinematic and power characteristics that determine the oscillating processes in metal structures during technological operations. Practical value. The developed computer model and the comparison of the results obtained with its help with experimental data obtained on bench equipment make it possible to predict load modes in the process of designing machines of a similar design.
