Abstract: In the course of Rail Vehicle Dynamics, the wheel / rail module of SIMPACK software is used to establish a typical dynamic model of railway vehicle, which can directly show the installation positions of key components such as rail, wheel set, motor, bogie, anti hunting damper, lateral stop, primary / secondary suspension system, etc., and help explain the important issues related to vehicle dynamics, such as operation safety The results show that the stability of the snake movement, the stability of the snake movement and the ability of curve passing. Practice shows that using SIMPACK software to assist teaching can make students more deeply grasp the theoretical knowledge and engineering application of rail vehicle dynamics.
Key Words: Rail vehicle dynamic; SIMPACK; Modeling and simulation;Course teaching
轨道车辆动力学是车辆工程专业(轨道交通方向)和载运工具运用工程专业教学的主要课程,体现了轨道交通系统的最根本的特色:车轮与钢轨的基础知识及应用。随着我国的铁路向高速、重载方向的发展、中心省会及大城市轨道交通的普及,以及人们对出行安全性、舒适性要求的提高,新型车辆及轨道结构不断出现,车辆动力学研究与控制也有了新的发展[1-3]。目前在教学过程中对关键知识点的讲解主要通过PPT图片、文字等方法实现,内容枯燥乏味,兴趣不高,企业实习有限,不利于学生对该课程重要性的认识及关键知识点的掌握[4-5]。因此,有必要在本课程教学中引入工程建模软件建立车辆动力学模型,结合模型及分析结果对课程中涉及到的重要理论及其工程应用进行讲解,不仅可以使学生对车辆关键部件结构工作原理有直观了解,而且还能提高学生运用课程知识点解决实际工程问题能力。……
