In the low-noise current collector using a delta-wing-shaped collector head in which the aerodynamics becomes quite large, it is desired to develop an active control using a force actuator. This paper deals with the numerical calculations of aerodynamics generated by a delta-wing-shaped collector head and a pair of insulators. A variation lift was verified to generate clear in the experiment results of high-speed test train with a full size prototype current collector. The conclusions of this research using a new current collector are as follows;(1) In the simulation result of an active control generated the average lift at 160 N, it was verified that the contact strip has same characteristics of contact force at max. 70 N as the conventional one.(2) The variation lift of the collector head at 350 km/h is expected to be 80 N lower than that before improvement.
