Abstract

The penetration of Electric vehicle market in India has given rise to an eco-friendly, efficient mode of transport. This work aims to answer the question of whether a powertrain change from an internal combustion engine to electric motor in an existing IC powered 125cc scooter, will change the handling performance of the vehicle. This work was carried out using multi-body dynamics simulation software called BIKESIMTM. The moments of inertia and mass properties were identified by modelling the vehicle chassis, along with the two different powertrains. A 15.6% increase in the overall mass of the vehicle and a 5% increase in the moments of inertia in the pitch, roll and yaw directions when the powertrain is changed from ICE to electric. A slalom test simulation in BIKESIMTM was used to evaluate the differences in maneuverability when the powertrains were changed. The observations from the simulation show a significant change of around 20% in the lateral acceleration, 16.5% in steer angle and 18% in the lean angle when the powertrain is changed from ICE to electric. The rider parameters also experience a deviation as the rider effort and steering torque of the electric powertrain is 14% and 28.5% more than its ICE counterpart respectively. These percentage increases in the handling parameters conclude that the conversion of an existing ICE powertrain to electric powertrain although feasible, will put the rider at a scenario of handling a significantly different vehicle.
基于BIKESIM <sup>TM</sup>
<div class="section abstract"><div class="htmlview段落">印度电动汽车市场的渗透催生了一种环保、高效的交通方式。这项工作旨在回答这样一个问题,即在现有的集成电路供电的125cc踏板车中,动力系统从内燃机改为电动机是否会改变车辆的操纵性能。这项工作是使用BIKESIM<sup>TM</sup>多体动力学仿真软件进行的。通过对车辆底盘以及两种不同的动力系统进行建模,确定了惯性矩和质量特性。当动力系统从内燃机改为电动时,车辆的总质量增加了15.6%,俯仰、侧滚和偏航方向的惯性矩增加了5%。在BIKESIM< TM</sup>用于评估动力系统改变时的机动性差异。仿真结果表明,当动力系统由内燃机改为电动时,横向加速度变化约20%,转向角变化16.5%,倾斜角变化18%。骑乘参数也出现了偏差,电动动力系统的骑乘力和转向扭矩分别比内燃机高出14%和28.5%。这些处理参数百分比的增加表明,将现有的内燃机动力系统转换为电动动力系统虽然是可行的,但将使骑手在处理一辆完全不同的车辆时处于一种情景。
