“…In the studies [15,16] dedicated to the design changes of the BR, there are unresolved problems of tapered dual wear of the pads due to the fact that their developers proposed to create various auxiliary devices to counteract forces that tilt the pads to the wheel only on the basis of kinetostatic analysis of the BR mechanism [17]. However, as practice shows, this approach is associated with the extra complexity of the BR design, extra cost and labour intensity of manufacturing and repair.…”

Application of heating control systems is rational for effective prevention of thermal-mechanical damages of the wheels and brake shoes of rolling stock. These systems enable to perform diagnosis of brake equipment elements and to evaluate the effectiveness of drum braking process in terms of wheel heating. The present study aims to assess wheel heating when drum braking and to define the most informative zones and threshold control values for heating control systems. Heating evaluation is conducted using finite element method under different braking modes. Research results are given as heating patterns in solid-rolled wheel of freight car; the influence of the air distributor mode on the wheel heating is considered, the most informative zones for heating control are identified.

The paper describes the existing directions and features in the field of non-destructive testing of thermosetting plastic products, in particular, brake pads of freight cars. The article presents defects that lead to a decrease in the declared resource of wheelsets as a result of interaction with the brake pad during operation. The process of enveloping metal is described. Describes production data provided by railcar repair companies, accompanied by illustrative material. Analyzed are methods of non-destructive testing, the use of which will reduce the damage to wheelsets, by selective testing of brake pads from each batch supplied to a repair facility or plant. Conclusions and tasks for further research are formed.
