Measuring scheme for determination of loads acting on the side frame of the bogie from a wheelset

The study aims to develop a measuring circuit determine the loads acting on side frame of bogie from wheelset when wagon is moving. paper reviews and analyzes experimental methods for vertical lateral forces Theoretical studies stress-strain state freight were carried out using finite element method under action axle opening wheelset. As result theoretical by method, places installation strain gauges determined, processing received signals was selected. developed scheme makes it possible spatial force effect wheelset, which possible, without increasing number channels in equipment, reduce considered while running dynamic tests. In addition, improves accuracy measurements loads, with help coefficient addition unsprung parts calculated.
