This project will use computer simulations to investigate the effect of VM molecular architectures on their stability and behaviour in lubricants in ranges of temperature, shear rates, and contact surfaces encountered in EV. Dissipative particle dynamics (DPD) simulations will be used. DPD method is a coarse grain method that allows simulations to be conducted in length scale and time scale that are close to those encountered in tribological contacts. The goal is to establish relationship among molecular architecture of additives, their stability and effectiveness. The knowledge can that be used to guide VM design for EV lubricants.

该项目将使用计算机模拟来研究 VM 分子结构对其在电动汽车中遇到的温度、剪切速率和接触表面范围内的润滑剂稳定性和行为的影响。将使用耗散粒子动力学（DPD）模拟。 DPD 方法是一种粗晶方法，允许在接近摩擦接触中遇到的长度尺度和时间尺度上进行模拟。目标是建立添加剂分子结构、稳定性和有效性之间的关系。这些知识可用于指导电动汽车润滑油的 VM 设计。
