INCREASE OF THE PERMISSIBLE LOAD OF S AND SS WAGONS. MEASUREMENTS TAKEN ON VEHICLES
The present report contains the results of the measurements taken on the vehicles in straight and curved track in order to determine the forces exerted on the track as a result of cant deficiency or excess and the random forces due to the movements of the suspended and non-suspended masses; regarding the non-bogie wagons also the forces exerted in the spring elements and in the wheel centers were measured. The first part contains a description of the evaluation procedures used in order to determine the various factors and, while taking into consideration two criteria defining the detrimental effects of vehicles on the track, it was found that the modern bogie or non-bogie wagons running with an axle load of 20 t and at a speed of 120 km/h are no more harmful to the track than the old type, non-bogie wagons running at a speed of 80 km/h with an axle load of 20 t. In the second part the results of the measurements on the constituent components of the wagons are discussed and it has appeared, regarding the non-bogie wagons studied, that a limitation of the axle load to 18t would be necessary at 120 km/h owing to the excessive stresses in the leaf springs of the suspension system.
