在进行机车车辆走行安全性、稳定性的研究以及转向架的设计时必须明确车体和转向架的质量特性。根据计算也可以求得质量特性的各值,但要付出很多劳动力和计算时间。在对有关长度、时间、重量等许多测试方法中,目前广泛采用的是电气式变换器,它与过去那种机械式的测量方法比较,其精度有了显著提高。一、质量特性的测试项目下列各项,对于转向架、车体质量特性
When conducting research on the safety and stability of rolling stock and the design of bogies, the quality characteristics of bodys and bogies must be clarified. According to the calculation can also obtain the value of the quality characteristics, but to pay a lot of labor and computing time. Of the many test methods for length, time, weight, and the like, electrical converters are widely used at present and their accuracy has been significantly improved compared to the mechanical measurement methods of the past. First, the quality characteristics of the test items The following, for the bogie, body mass characteristics
