| dc.description.abstract | In Taiwan, most disabled People use modified scooter to solve their demand in traffic. The purpose of this study is to build a numerical simulation technology by integrating CAD modeling and CAE analysis for modified e-scooter. The research will discuss the effect of different on-road factors such as road type, battery position, auxiliary wheel type, rider’s weight and velocity on riding comfort and fatigue durability. Furthermore, the accuracy of numerical simulation technology was testified by a high-fidelity road simulator.
In this study, two different experiments were designed. The objective of the first experiment was to verify the accuracy of numerical simulation. The objective of the second experiment was to understand the effect of on-road factors on riding comfort and fatigue durability of modified e-scooter frame. On the development of numerical simulation technology, we used the Pro/Engineer to create a scooter frame and imported it into the ADAMS for whole vehicle dynamic vibrating simulation. Then, we calculated the acceleration history and loading history. The second, we adopted the ISO 2631-1 standard to evaluate the riding comfort level. Meantime, we imported the loading history into the ANSYS software and calculated the stress history of e-scooter frame. Finally, we used the high cycle fatigue theory to evaluate fatigue durability.
Experimental data showed that the simulated results of ADAMS and ANSYS analyses were similar to those of road simulation testing. It verified the accuracy of the present numerical simulation. Moreover, analytic results revealed that higher velocity or tossing road would lead to the inferior riding comfort and fatigue durability of e-scooter frame. The increase of rider’s weight resulted in better riding comfort but poor fatigue durability. When battery under the e-scooter bottom would lead to better riding comfort and fatigue durability. We believed that these findings
would be helpful for company which would improve the e-scooter design.
