ДОПОЛНЕННАЯ РЕАЛЬНОСТЬ ЭМУЛЯЦИИ РЕЛЬЕФА МЕСТНОСТИ И НЕШТАТНЫХ СИТУАЦИЙ В ТРЕНАЖЕРАХ ТЕХНИКИ ДЛЯ АПК

Abstract

The practical skills of agroengineers include the skills of operating technical means used in the agricultural sector. The variety of brands and modifications of training simulators and their functionality creates difficulties in obtaining the full range of skills required fror operating transport and technological machines. To expand the practical skills of students, the authors conducted analytical and patent studies of training simulators. As a result, they present a simulator using the technology of augmented reality terrain emulation, which can simulate dynamic force effects on the vehicle cab, when driving at a uniform speed on roads with different surface profiles and rotation angles, displaying the dynamics of translational motion with visual images. The impact of the vertical road terrain on the vehicle and the operator’s cabin is simulated by four vertical linear pneumatic actuators acting on the inclined platform using control devices, by means of short-term lifting and the return movement of the rods. The lifting height is modeled by the pressure in the receiver and the duration of the open state of the valve and is consistent with the road relief-modeling program. With the controls, the trainee simulates the control of the vehicle movement along the road. The central microprocessor device displays an image of the road with a visible profile of rhe vehicle’s body part and the trainee, who feels the dynamic effect on the receptor-muscular system through mechanical movements of the simulator cabin, creates a psychophysical perception of the full range of real control factors over the machine. The proposed prototype of the training simulator for the movement of a technological vehicle will increase the effectiveness of training operating skills.
