“…В данных комментариях наиболее широко отражены технические особенности манипуляторов. Так, в отличие от стреловых кранов, оснащенных решетча телескопическими стрелами, краны-манипуляторы имеют шарнирно-сочлененное ст оборудование, состоящее из отдельных звеньев переменной длины, установлен (6) где Р -вес груза; G c -вес стрелового оборудования, приведенный к оголовку стрелы; b -вылет.…”

“…Это обусловлено в первую очередь отставанием нормативных документов от изменяющихся условий технической эксплуатации автомобильных шасси, что в свою очередь повышает аварийность при эксплуатации грузоподъемной техники. Ведущие научные центры России и развитых стран совершенствуют методики расчета элементов грузоподъемных кранов и их грузовой устойчивости [3,2,3,4,5,6,7,8,9,10,11,12,13]. Для автоматизации расчетов при проектировании используют математическое моделирование, которое позволяет более точно определить опасные сечения в металлоконструкциях, тем самым снизить риски возникновения аварийных ситуаций [14,15,16,17,18,19,20,21,22,23,24,25].…”

Introduction. The main requirement for lifting equipment is a strict compliance with safe operation measures. Therefore, special attention is focused on this issue when designing each unit of the equipment. However, despite the extensive list of the current normative documents and systematic monitoring, according to the annual official reports of the Federal service for environmental, technological and nuclear supervision over recent years the facilities that use lifting structures have high indicators for the number of accidents. In addition, the study of a load stability ratio determining in the design of automotive hoisting cranes and automotive manipulator cranes is particularly relevant at the present time due to a wide development of new lifting equipment as the development of the market for cranes has resulted in the occurrence of new technical issues in design and manufacture this type of lifting equipment. As part of the research work to improve the accuracy of calculating the load stability of automotive hoisting cranes and automotive manipulator cranes based on the analysis of existing normative and technical documents the possible occurrence of the accidents causes due to imperfection of regulatory instructions or non-compliance with regulatory instructions during design manufacturer work was considered.Materials and methods. This article is devoted to the study the fundamental principles of the nominative documents regulating the design and operation of the automotive hoisting cranes and automotive manipulator cranes. Both of the current and archived nominative documents in the field of lifting equipment are considered. Special attention is paid to the issues of determining the load stability of the automotive hoisting cranes and automotive manipulator cranes.Discussion and conclusion. The key differences in the calculating method of the load stability of the automotive hoisting cranes and automotive manipulator cranes are highlighted. The accidents statistics of load-lifting mechanisms and lifting structures of the Federal service for environmental, technological and nuclear supervision are given. The main causes of lifting equipment accidents are highlighted. The ways of solving the modernization of the existing methodology for determining the load stability of automotive hoisting cranes are proposed by including previously unrecorded factors related to the technical features of the chassis which contributes to improving the accuracy of the obtained values of the load stability ratio.

“…The kinematic problems of truck cranes were further described in Works [1,18], where the kinematics of point Ω were presented. The control of this type of system takes place through changes of the following coordinates: r-boom length, θ-boom inclination angle, ϕ and α (where α = ϕ + π)-boom and crane body rotation angles.…”

“…In Paper [11], wind power impact on a container crane located in atmospheric boundary layers was considered, where wind power was measured with the use of a seven-component balance with different wind directions. The problem of positioning, work cycle optimization, and development of monitoring systems for a carried load were presented in Papers [6,[13][14][15][16][17][18]. In the optimization process, new technological approaches were used (i.e., LiDAR scanner [13], three-dimensional (3D) visualization [15], or fuzzy-set logic models [19]).…”

This paper considers the coupled kinematic and dynamic models of a mobile crane. A full description of boom and load movement has been provided as a response of the system to the influence of kinematic forces. The linear system model was treated as rigid, and the carried load as a nondeformed static body. To describe the position of said load, Bryant angles were used. The dynamic model includes the impact of external forces (wind pressure) while load carrying and positioning. Algorithm and calculation software were developed to enable dynamic phenomena analysis during both a work cycle and free movement of said load. The initial problem was solved by means of the ode45 calculation procedure in the Matlab software based on the Runge–Kutta 4th Order Method. The work presents exemplary results of load movement simulation with respect to various wind velocities, selected on the basis of guidelines from Poland’s standards regarding safe operation of mechanical equipment.

“…According to dynamic model with seven degrees of freedom and scale model [5][6][7] , we established the virtual prototype simulation model, which is mainly composed of body, tires, power, etc. Modeling process is as follows: (1) We established basic component of the scale model in the ADAMS/VIEWS; (2) Confirmed the topology of the components and combined the components.…”

This paper is focused on orchard vehicle rollover and tipping problems in its operation process. Firstly, seven degrees of freedom orchard vehicle ADAMS model is established. And then, it built up a driving stability control algorithm to adjust input speed by real-time pitch angle, roll angle and other state parameters. After that, ADAMS and MATLAB joint simulation control model is setup for doing simulation experiments with which results can be used to adjust the coefficients of control model. Finally, it also established physical scale model at the same time to verify simulation results. The experimental results show that orchard vehicle control driving stability model, which proposed in this paper, can effectively prevent the orchard vehicle tilting, and can improve the driving stability.
