The paper deals with the digital transformation of engineering education. Such transformation is justified in terms of an engineering education paradigm change. Based on a comprehensive analysis of the didactic system of engineering education, the authors specify the requirements for such important engineering education components as goal setting, content, educational technologies, assessment tools and methods in current educational environment. They provides examples of a practical digital transformation of a number of engineering curricula and syllabi by integrating blended learning based on a Small Private Online Course (SPOC). The authors share their best practices in designing e-learning taking into account the features of the learning-forgetting process, they demonstrate how to make use of the saved time for students’ practical work, how to implement gamification techniques based on such new forms as the Hackathon, Internet of things (IoT) for engineering education. They also provide examples of creating a digital educational environment with specialized software modules to visualize complex mathematical concepts as well as examples of applying principles of artificial intelligence and machine learning to shape a student’s adapted educational trajectory. They discuss how to identify student’s problems with learning material assimilation and suggest a specially developed course including propaedeutic unit for additional study.
One of the main methods to predict permeability is a simulation of the motion of wheeled vehicles in different operating conditions, which are based on mathematical models of interaction between elastic tires with deformable irregularities of the support base. Currently in the theoretical study of the interaction of propellers with the ground formed two main directions: analytical method involving a mathematical description of the process under study and the finite element method based on computer simulation. The aim of this study is to develop a mathematical model of rolling elastic wheels on deformable rough reference base, taking into account the deformation of the contact patch at each end of the elementary playground. A mathematical model of the curvilinear rolling of the elastic wheel on an uneven elastic-visco-plastic support base is developed, taking into account the deformation of the contact spot in each finite elementary site; the influence of ground hooks on the parameters of the wheel movement; coupling properties of the support base in the horizontal direction under the action of a vertical load; change in the direction of radial and tangential reactions; elastic- visco-plastic properties of the support base;“history” of loading of each elementary platform of the support base; condition of the support base on its physical and mechanical characteristics.
Currently, two-axis front-wheel drive vehicles are widely used systems that provide increased stability and manageability by connecting the rear axle and redistributing torque between the driving axles and between the driving wheels of the rear axle. To a lesser extent, drive schemes for rear-wheel drive two-axis cars with a plug-in front axle are common, and, accordingly, the issues of traffic stabilization of such cars are not fully studied. The purpose of this work is to increase the stability and controllability of rear-wheel drive two-axis machines with a plug-in front axle by redistributing torques between the driving wheels. The analysis of the effectiveness of the 4x4 vehicle traffic stabilization system by redistributing torques between the driving axles and the wheels carried out by simulation methods allowed us to establish that the following stabilization methods are the most effective for cars with a plug-in front axle
• a 4x4 vehicle with a plug-in front axle that redistributes torques between the driving wheels of the rear axle (the effectiveness of these stabilization methods is approximately the same)
• a 4x4 vehicle with a plug-in front axle and an automatically locked front-wheel differential;
• 4x4 vehicle with a plug-in front axle with individual braking system for individual wheels.
One of the most important properties of semi-trailer trucks are stability and steerability. This is because with an increase in driving speeds, these properties largely determine the safety of vehicle operation. Improving the semi-trailer trucks safety is all the more relevant because the consequences of road accidents involving semi-trailer trucks are the most severe and cause enormous damage. One of the most common causes of accidents is the loss of stability during emergency braking in a turn, especially in the event of a failure of trailer braking system. The goal of this research is to develop principles for improving the stability of semi-trailer trucks movement during emergency braking in a turn and failure of trailer braking system. A method has been developed to increase semi-trailer trucks stability during emergency braking in a turn and the failure of trailer braking system, which allows to maintain the trajectory stability of the semi-trailer truck and to avoid accidents with severe consequences. Using simulation methods, the effectiveness of the proposed method is proved.
