Contact force between pantographs and overhead contact line used to evaluate contact quality should be measured properly. Nowadays, force sensors are usually assembled in pantograph head that appearance and dynamic performance of pantograph could be changed and influenced. To solve the problem, the authors designed a rod-type force sensor to replace the pantograph head pivot. At first, it is theoretically analyzed that force sensors can be placed not only in pantograph head but also in frame, and inertial correction is required. Aiming at a domestic pantograph, a force sensor was designed based on calculation. Furthermore, test results show great linearity and accuracy, which is over 90% with only inertial correction of pantograph head that satisfied the requirement of EN50317. With full correction, accuracy of the measurement system can reach 94%.
