Abstract

This article discusses and analyzes mechanisms based on the principles of parallel kinematics, designed to perform various technological actions, with the movement of the executive body along complex spatial trajectories. Mechanisms with parallel structures have wide possibilities for solving various problems of application of equipment and technologies. Promising are the tasks associated with the use of mobile bases in various simulators to gain skills in controlling equipment (aircraft, cars, specialized military equipment). To conduct research on kinematic and dynamic characteristics, a digital layout of the platform has been developed – a parameterized 3D model in a CAD system. The platform represents a system with six degrees of mobility, which are implemented on the basis of a mechanism with a parallel structure. A description of a dynamic simulation model with six degrees of mobility developed using the MSC Adams software environment is given. The model is intended for research at the stage of design work in the development of simulators of various vehicles. The developed dynamic model was tested in order to implement a methodology for conducting research on the kinematic and dynamic characteristics of the platform based on simulation modeling. The results determining the capabilities of the model for determining the dynamic and force parameters in individual elements of the platform at the specified geometric parameters of the platform design are presented. The methodology of studying the digital layout of the platform by simulation modeling consisted in the execution of the accepted trajectories by the model, taking into account the technical characteristics of the actuators. At the same time, certain dynamic indicators were recorded and processed. As a result, graphs of changes in velocities and accelerations of the center of mass, as well as force characteristics (the sum of forces applied to the body in the hinge) when performing the corresponding trajectories are constructed.
