本研究课题的目的是利用车辆间的车钩作为力传感器,提出利用作用在车钩上的力与车辆的加速度,以推断编组内任意车辆的制动力的方法的建议。介绍了根据车钩力与加速度以推断制动力的具体方法,并论述了在使用了货物列车的现车试验中应用了建议方法的结果,并指出,可用适当精度推断编组内任意车辆的制动力。 The purpose of this research project is to make use of the coupler between vehicles as a force sensor and propose to use the force acting on the coupler and the acceleration of the vehicle to deduce the braking force of any vehicle in the formation. The method of deducing the braking force based on the hook force and acceleration is introduced. The results of applying the proposed method in the current vehicle test using the freight train are also discussed. It is pointed out that the braking force of any vehicle in the group can be deduced with appropriate accuracy.
