Other AbstractThe aerodynamic characteristics of high-speed trains passing by in open air are numerically analyzed on the basis of moving mesh.Then,the Steinheur empirical formula for calculating air pressure pulse amplitude is mo- dified,and a new formula is presented.The results show that (1)the pressure pulse amplitude of low-speed trains passing by in open air is less than that of high-speed trains;(2)the amplitude is related to crossing speed,track- ing distance as well as monitoring point height,and is basically proportional to the traveling speed square of trains; (3)smaller tracking distance results in higher amplitude;and (4)tracking distance has a greater effect on the am- plitude in comparison with monitoring point height when other conditions keep constant.
