resistance braking

Engine working conditions were simulated by drive motor, the road resistance was simulated through electromagnetic brake controlled current to achieve the control of braking torque.

采用驱动电机模拟发动机工况，利用电磁制动器控制电流实现制动力矩的控制来模拟道路阻力。

The Effects of Train Braking and Ballast Resistance on the Longitudinal Force in Rail

列车制动与道床阻力对钢轨纵向力的影响分析

Then the optimum braking time value of additional resistance is calculated.

然后采用能量法计算该阻值下的制动时间；

There are several formulae for checking calculation of slipping of crane ( CCSC in short), such as based on traction force and external resistance, also based on brakeage and braking resistance.

起重机打滑验算公式很多。如有用牵引力、外阻力验算起动打滑的，也有用制动力、制动阻力验算制动打滑的。
