车体参数测定方法研究
On Measuring Methods for Parameters of Car Body
-
摘要: 在论述车辆动力学参数的重要性的基础上,提出了车体重心、重量、转动惯量的测定方法,分析和比较 了测定方法的先进性和可行性,给出了参数的计算方法和计算公式,最后介绍了实车测定情况和测定结果。Abstract: Based on the discussion of the significance of measuring the car bodies dynamic parameters of railway vehicles, the methods tomeasure a car body sweight (mass), center of gravity and moment of iner- tia are proposed. The advantages and feasibilityofthese methods are analyzed and compared, and the calcu- lation methods and calculation formulas for the parameters are given. In addition, the car body s parameter measurement of an actual passenger car is introduced and the measured results are presented.
