- Abstract
With the increasing of the maximum running speed and the complicated environment that the current collector is exposed to, it is urgent and necessary to study the dynamic characteristics of the current collector under the high speed running condition. In this paper, the current collector used in the vehicle of Guangzhou Metro Line 14 (the maximum running speed is 120km/h) is considered as the object of the study. The irregularity of the third rail is used as the input excitation and the random vibration is considered while the vehicle is running. Four factors which include the stiffness and the damping of the tension spring, the length of the swing arm, as well as the gravity center position of the shoe are analyzed on their impact to the dynamic response of the current collector at the speed of 120km/h. The contact force of the current collector and the third rail, the displacement and the vertical acceleration of the shoe are considered in the dynamic characteristics. As a consequence, the influence of different factors on the quality of current collecting is analyzed and the improvement of the optimal design is put forward. The simulation results demonstrate that the improved collector can perform better in the quality of current collecting than before
