E-tricycle vehicle design based on parametric CAD/CAE models

Introduction. National Technology Initiatives (STI), designed to develop and implement High-Tech tools into engineering practice and based on the Industry 4.0 concept, require appropriate technical solutions for all phases of the product lifecycle from design to disposal. Implementation of the concept involves the formation of technological groups and markets in different directions in particular one of the emerging markets of STI is Auto.Net. At the same time, the product design stage is basic and should be implemented in a form ensuring the entire life cycle of the product on the principles of this concept. Materials and Methods. The article presents the methodology and results of designing an electric vehicle-tricycle in the integrated CAD/CAE systems. The design process is the development of digital parametric models of different types and levels on a top-down and bottom-up basis. The parametric properties of models provide the ability to develop design solutions efficiently, including design, analysis and optimization. The design solutions are developed in the CAD/CAE/CAM/PDM/PLM SolidWorks (Motion, Simulation) software. Results. The results of the study are rational design paths for the structures of the class under consideration in the SolidWorks software, as well as design solution of the electric tricycle-vehicle in the form of a system of integrated parametric models, including 3D models of parts and assemblies, models of solid-state mechanics, finite-element models for solving problems of mechanics of the deformed solid body in the form of linear and non-linear statics, linear dynamics, parametric optimization. Videos of the results are provided for illustrative purposes. Discussion and Conclusion. In the research, the design trajectory of the electric vehicletricycle based on correct formulation for the design problems and providing the rational choice of means, tools, and technologies from basic SolidWorks functionality is presented. The trajectory provides both an efficient solution to design problems and an assessment of the adequacy of the results obtained. In terms of the possible perspective of this work, it is necessary to specify the solution of optimization tasks according to various criteria of project efficiency and the development of an integrated (cyber-physical) model of electric vehicle-tricycle, which meets the requirements of digital twins. At the same time, bidirectional associative links between virtual and physical components of the integrated model will solve a number of additional problems: control of the accuracy of digital models, giving the digital model synergistic properties, planning of the trajectory and unmanned control on the principles of IoT (Internet of Things).
