  • Fully continuous ground measurement method and system for wheel rail vertical force
    Patent number: 10745037
    Abstract: A continuous measurement method for a wheel/rail vertical force includes: continuously arranging classic wheel/rail vertical force unit measurement areas in a form of “shear force+support force” on rails, where adjacent unit measurement areas share an end shear force measurement, and each two adjacent unit measurement areas form a unique compound measurement area; obtaining the wheel/rail vertical force when a wheelset passes the unit measurement areas other than the transition area of shear force measurement by using the classic unit measurement areas; obtaining the wheel/rail vertical force when the wheelset passes the transition area of the shared shear force measurement by using the unique compound measurement area; and combining all wheel/rail vertical forces on the unit measurement areas and the compound measurement areas to obtain a long distance fully continuous wheel/rail vertical force of the wheelset.
