Abstract

Abstract Electrically assisted bicycles lead to a change in the driving characteristics compared to conventional bicycles because of the additionally attached masses of motor and battery. In order to describe the resulting interaction of the electric drive components on the driving characteristics, this paper examines simulations of the driving behavior of bicycles with different positions of battery and motor in open- and closed-loop tests. The integration of human driving behavior by control loops allows the evaluation of driving characteristic under more realistic driving conditions compared to the existing studies of the eigenbehavior. The results are analyzed using characteristic values that describe the system behavior in a suitable way. Furthermore, a design of experiments is performed to classify the influence of the presented research results in relation to other system parameters, such as different types of bicycles and different rider postures.

基于多体仿真的电动自行车行驶特性研究

与传统自行车相比，电动自行车由于增加了电动机和电池的质量，导致其行驶特性发生了变化。为了描述电动驱动元件之间的相互作用对自行车行驶特性的影响，本文在开环和闭环试验中对不同位置的电池和电机的自行车行驶特性进行了模拟。与现有的特征行为研究相比，通过控制回路对人类驾驶行为的整合，可以在更真实的驾驶条件下评估驾驶特性。用描述系统行为的特征值对结果进行分析。此外，还进行了实验设计，将研究结果与其他系统参数(如不同类型的自行车和不同的骑车人姿势)的影响进行分类。

期刊介绍： The journal Multibody System Dynamics treats theoretical and computational methods in rigid and flexible multibody systems, their application, and the experimental procedures used to validate the theoretical foundations. The research reported addresses computational and experimental aspects and their application to classical and emerging fields in science and technology. Both development and application aspects of multibody dynamics are relevant, in particular in the fields of control, optimization, real-time simulation, parallel computation, workspace and path planning, reliability, and durability. The journal also publishes articles covering application fields such as vehicle dynamics, aerospace technology, robotics and mechatronics, machine dynamics, crashworthiness, biomechanics, artificial intelligence, and system identification if they involve or contribute to the field of Multibody System Dynamics.
