连续测量轮轨接触位置装置的开发

对车辆脱轨安全性进行的评价一般依据脱轨系数进行,但难以作出确切的评价.针对这一问题,本文介绍了能够对轮轨接触位置等参数进行连续测量的装置.该装置不仅可以测量轮轨的接触角和横向蠕滑力,还能修正轮轨横向力,得到的数据具有较高的可靠性.

Development of the Device for Continuous Measurement of Wheel-Rail Contact Positions

The evaluation on the derailment safety of vehicles is usually made on the basis of derailment coefficient, but the exact evaluation is difficult to be made. In view of this problem, a device is developed to make the continuous measurement of such parameters as the wheel-rail contact positions. The device not only can measure the wheel-rail contact angle and lateral creep forces, but also can rectify the lateral wheel-rail force. The data obtained have fairly high reliability.
