中文摘要:通过分析描述轮胎摩擦力与滑移率关系的Magic模型,根据其关系曲线形状进行假设,利用二阶系统传递函数的直接识别方法,得到了由指数函数和双曲函数组成的简单建模方法,所建模型能够准确地描述摩擦因数与滑移率间的变化关系。

Abstract: Based on analysis of Magic formula which describes relationship of tire friction and slip rate,and making presumption according to its curve, a new simple approach was put forward using method of direct identification transfer function of second-order system. The model derived using new method is composed of exponential and hyperbolic functions,which can be used to describe relationship between friction force and slip rate correctly and conveniently.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
