Railway vehicles of pneumatic suspension have a tendency to produce large wheel road variation on a twisted curve due to operation of the height control valve of air springs installed between both side air springs of the truck. In this paper, equations of moment equilibrium of the pneumatic suspension vehicle on the twisted curves are introduced quasi-statically, and effects of nonlinear characteristics of the height control system on the wheel load variation are analyzed. Analytical results are also examined by using the full size model test apparatus. The result shows preset pressure value of the air pressure balance valve plays an important role on the wheel load.
