Application of Simulation Software in Optimization of Powertrain of Pure Electric Vehicle

Abstract

— Pure electric vehicles are a research hotspot in today's new energy vehicle industry. Its core is the electromechanical coupled drive system (drive motor and gearbox), and its performance affects the overall performance of pure electric vehicles. The application of industrial software for electromagnetic design, electrothermal design, electromagnetic vibration and noise optimization of drive motors, heat transfer analysis, fatigue analysis, and noise optimization analysis of gearboxes has become important technologies for designing and manufacturing the core components of electromechanical coupling drive systems.This article analyzes the current status and existing problems of the development of simulation software for the core components (drive motor and gearbox) of the electromechanical coupling drive system of electric vehicles, and proposes solutions to key technical problems, and proposes the development direction of unified simulation of drive motor and gearbox on the electromechanical coupling platform

Comparative Study on the Attributes Analysis of Software Development Cost Model Based on Exponential-type Lifetime Distribution

“…The reason is that the probability of finding the remaining flaws at the latter stage gradually decreases. In the end, it means that the development cost increases even more towards the latter stage [18].…”
