Purpose: To describe the first results of a unique experience of Emperor Alexander I St. Petersburg State Transport University (PGUPS) as a branch transport university where there has been created a school of engineering entrepreneurship in the university scientific-educational ecosystem. Methods: System analysis of open sources of the Internet and of PGUPS development program till 2030; as well as ecosystem, modular and project approaches for organizing the work of engineering entrepreneurship school. Results: The study shows that the search for effective formats for the development of human capital becomes particularly relevant in ensuring national technological sovereignty, and the creation of an engineering entrepreneurship school on a university basis as a new format for generating and integrating innovations is a time dictate. The key purpose of an engineering entrepreneurship school is an intellectual elite preparation by educational modules of entrepreneurship, engineering and inventive creativity of students with the formation of a unique pool of competencies in organization and management of full lifecycle of projects, innovations and high-tech production. It is noted that a branch university image is transformed into an ecosystem capable of creating a unique entrepreneurial space for involving students, employees and industrial partners into their own know-how hub. Practical significance: The application and subsequent scaling of the unique experience of PSUPS as a branch university will allow to pursue outrunning training of human capital with expanded scarce competencies and will form growth points in the competitiveness of transport education in modern Industry 4.0. Keywords: school of engineering entrepreneurship, ecosystem, transport university, innovative educational project, Industry 4.0, University 4.0
A.G. Andrievsky, E.A. Chaban, V.V. Moskvichev Durability assessment and rational fastening to Traction Engine of gear housing of an electric locomotive [more] [back]
Purpose: To investigate the dependence of workload of an electric locomotive gear housing on the parameters of its attachment to a traction motor. To determine own oscillation frequencies under various conditions of its attachment to a traction motor. To propose technical solution allowing to reduce the workload of gear housing in the case of abnormal operation of its attachment to a traction motor. To propose an algorithm for housing lifetime calculation taking into account its fastening parameters. Methods: The values of gear housing own frequencies are obtained by solving the system of Lagrange differential equations of the second kind. Created with this purpose mathematical model of mechanical system under consideration takes into account an elastic nature of housing attachment to a traction motor. Results: The influence of conditions and parameters of gear housing attachment to a traction motor on its workload and, correspondingly, its lifetime is shown. The algorithm for gear housing lifetime calculation is proposed, taking into account its fastening conditions and parameters. The significant influence of workload abnormal modes on housing durability is shown. Practical importance: Constructive solution is proposed that reduces gear housing workload in the case of abnormal conditions of attachment to a traction motor. The algorithm for estimating gear housing durability in the case of redistribution of workloads between its reference points has been developed. Keywords: gear housing, bolt fastening, housing dynamics, workload dynamic workload, durability
A.V. Atamanyuk, Ya.S. Vatulin, A.A. Vorobyov, I.Yu. Novoselsky Computer Simulation of Load-Handling Device of Automatic System for Unloading-Supply of Rail Straps at Rail Welding Enterprise RWE-1 [more] [back]
Purpose: Modernization of rail unloading-supply technology of rail unloading-supply automatic system with the development of multifunctional rail grip and the definition of compliance degree of being used I-beam 36M as a monorail to new requirements for a strength. Methods: Computer modeling of solid virtual model of being designed rail grip is developed in the environment of computer-aided design system SolidWorks. Results: Load-carrying beam of unloading-supply automatic system (USAS) lifting device with a new grip is calculated. It’s found that the I-beam as of 36M grade fully meets required strength and rigidity conditions at installing a new grip on a solid plot. Practical significance: Design of automatic rail grip is designed that’s reckoned upon work with one or three rails simultaneously.
