Theory and practice of the innovative spring suspension design for locomotive to improve its traction and dynamic characteristics.
This paper deals with the methods and techniques of the locomotive dynamic characteristics improvement, decrease in force impact on the track, minimizing tire and rail wear by secondary suspension improvement. Based on the calculations carried out using the created mathematical models and experimental research, there are proposed series of construction solutions of the supporting and returning devices with rational characteristics, which allow improving traction characteristics of the locomotive and reducing its dynamic impact on the track in vertical as well as in horizontal planes, on the straight track as well as on the curved track. Moreover, the proposed solution can provide the locomotive body with the centering function relative to the bogie. The proposed body to bogie connection was tested using a special test stand and in operating conditions. According to the test results, the proposed construction of body to bogie connection can ensure the required rigidity and damping characteristics due to the design optimization.
