| Περιγραφή: | Problem. Mobile lifts with working platforms have found wide application in various fields of industry. One of the main requirements when designing such machines is to ensure the stability and trouble-free performance of technological operations. The article presents the results of the development of a digital three-dimensional model of such a machine, and also describes virtual studies on controlling the machine's movement at different positions of the running gear. Goal. It was decided to divide the entire set of tasks to be solved into clusters in which it is possible to obtain reliable information with minimal time for the development of the models, as well as with the least load of the software. The main task was to develop a computer model of the running gear to study the maneuverability of the machine. Methodology. Geometric modeling was performed with limited initial data, the properties of the materials used for parts were not taken into account, and welding was not modeled. However, the geometry of the frame and all components was reproduced almost completely in the dimensions and configurations of the real object. Results. The computer model enabled establishing of the dependence of the machine's turning radii from the geometric design parameters of the chassis, as well as from the turning patterns and position of the longitudinal beams. Originality. The computer model made it possible to maneuver in three independent schemes: the classic 4x2 wheeled vehicle turning mechanism, turning with all four wheels (on the front and rear axles in opposite directions), and when all wheels turn in one direction, the so-called "crab stroke". Practical value. The proposed models and algorithms will significantly speed up the design process for this class of vehicles. У статі представлені результати огляду основних світових тенденцій та напрямків геометричного моделювання деяких технічних об’єктів і машин, а також показані можливості створення різноманітних 3D моделей за допомогою програмного пакета Autodesk Inventor і результати віртуальних досліджень у середовищі Dynamic Simulation, що виконані на цих моделях. |
