项目摘要

The central goal of this research is to reduce emission in transportation vehicles. Transportation vehicles account for close to 30% of air pollution in Canada. An active approach to reduce this pollution is electrification of vehicles. All major automotive manufacturer are planning to move toward electric vehicle and/or a mixture of electric and internal combustion hybrid vehicles. These emerging vehicles bring with them new design challenges that, in part, stems from new materials that are less known to automotive industry. Electrical steel is among those materials that are used in rotors and stators, main components of electrical engines. Due to the favorable magnetic properties, i.e., low iron loss and high permeability, electrical steels are preferred steel material widely used in construction of electrical engines. These steels come in the form of very thin sheets that are stacked to form a rotor or stator frame. Knowledge of their mechanical properties in the form of sheets and stacked laminates are of principal importance in design and manufacturing of electric engines and their long term durability. The proposed research studies the material and mechanical characteristics of a single sheet and stacked laminates under quasi-static and cyclic loads at room and elevated temperatures.

这项研究的中心目标是减少运输车辆的排放。交通工具占加拿大空气污染的近30%。减少这种污染的一个积极方法是车辆电气化。所有主要汽车制造商都计划转向电动车辆和/或电动和内燃混合动力车辆的混合。这些新兴的汽车带来了新的设计挑战，部分原因是汽车行业不太了解的新材料。电工钢是用于转子和定子的材料之一，转子和定子是电动发动机的主要部件。由于有利的磁性，即，低铁损和高导磁率的电工钢是广泛用于制造电机的优选钢材料。这些钢以非常薄的片材的形式出现，这些片材堆叠以形成转子或定子框架。了解它们在片材和叠层形式下的机械性能对于设计和制造电动发动机及其长期耐用性具有重要意义。拟议的研究研究在室温和高温下的准静态和循环载荷下的单片和堆叠层压板的材料和力学特性。
