Transportation is an indispensable part of human beings’ daily life, thus plenty of scholars have focused on improving the energy efficiency of transportation. The application and development of aerodynamics is of paramount importance. In this article, the effects of three types of locomotives on aerodynamic performance of high-speed trains are investigated. In order to lucubrate this topic, the definition of aerodynamics by different scientists is firstly discussed and showed, they basically classify them by three different kinds of ways. Subsequently, the creation of aerodynamics, historical development, and present situation are briefly introduced. In the main part, mathematical model and calculation formula are carried out to ensure which kinds of aerodynamic model is the most suitable among all the designs. Overall, these results offer a guideline for how to design a more effective and practical train head by applying the aerodynamic knowledge and expanding people's use of aerodynamics.
