弓网接触力是评价电气化铁道受流性能的重要指标。然而，通过常规方法测量接触力的频率范围不足以达到此目的。为了准确测量接触力，需要精确估算云台的惯性力。然而，当用现有的方法测量时，在高频区域中的惯性力中出现大的误差。本文提出了一种新的接触力测量方法，该方法利用云台上多点加速度的测量值，即使在高频区也能精确地估算云台的惯性力。理论计算和受电弓激振试验的结果表明，该方法是一种有效的精确测量方法。
The contact force between pantograph and contact wire is an important factor to estimate the performance of current collection of electric railways. However, the frequency range of measuring the contact force by the conventional method is not sufficient for this purpose. To measure the contact force accurately, it is required to precisely evaluate the inertia force of panhead. However, large errors occur in the inertia force in the high frequency region when measured by the existing method. This paper proposes a new method to measure the contact force, which can evaluate the inertia force of panhead precisely even in high frequency region by using the measurements of acceleration at plural points on the panhead. The results of theoretical calculation and excitation test of a pantograph can show that this method is effective for accurate measurement.
