【摘要】：以人体肌肉疲劳程度为评价标准,基于人体生理学、人机工程学和仿真试验技术,研究一种自行车结构参数设计的有效方法。以某自行车厂生产的一款公路自行车为例,在Anybody生物力学软件环境下建立人-车耦合系统模型;通过肌电信号试验及心肺功能测试,对人-车耦合系统模型进行了试验验证,确保仿真系统可靠;借助验证后的仿真系统进行了一系列仿真试验,以人体下肢肌肉受力为主要研究对象,分析了相同骑行速度、负载下鞍座位置与人体肌肉受力之间的映射关系。结果表明:对于同一骑行者,自行车鞍座位置对于其肌肉受力值的影响很大,即对其疲劳程度影响很大。分析方法与结果为自行车车架结构设计提供了依据,为自行车设计提供了新思路。
[Abstract]:Based on human physiology, ergonomics and simulation test technology, an effective method for the design of bicycle structural parameters is studied based on the fatigue degree of human muscle. Taking a road bicycle produced by a bicycle factory as an example, the human-vehicle coupling system model is established under the Anybody biomechanical software environment, and the man-vehicle coupling system model is verified by the EMG test and the cardiopulmonary function test. To ensure the reliability of the simulation system, a series of simulation experiments were carried out with the help of the verified simulation system, and the same riding speed was analyzed with the force of human lower limb muscles as the main research object. Mapping relationship between saddle position and muscle force under load. The results show that for the same cyclist, the position of bicycle saddle has a great influence on the muscle force value, that is, the fatigue degree is greatly affected. The analysis method and results provide a basis for the design of bicycle frame structure and a new way of thinking for bicycle design.
