Розробка тривимірної моделі системи «рама візка - тягові електродвигуни» для електровоза ЧС4 за допомогою програмного продукту SolidWorks

Abstract

UA: У статті розглянуто недоліки в існуючій моделі рами візка електровоза ЧС4, пов’язані з ослабленням кронштейнів кріплення, а також технологією монтажу тягових двигунів. Здійснено розробку тривимірної моделі рами візка з двигунами за допомогою програмного продукту SolidWorks. Проведено розрахунок власних частот за допомогою програмного продукту MSC.Patran.

EN: At the present stage of development of the railway industry, it is necessary to generate and implement progressive solutions in the design of rolling stock in order to increase the traction rolling stock reliability and efficiency of its use. The article deals with the drawbacks in the existing model frame truck of the electric locomotive associated with the weakening of the bracket mount, as well as the technology of traction motors. This was developed for this purpose of a three-dimensional trolley frame model with engines using the SolidWorks software has been developed. Сarried out frequencies calculation using MSC.Patran software product. The estimation of magnitudes of oscillation amplitudes and eigenfrequencies is carried out. The article is proposed ways of elimination of the revealed problems with the help of introduction of additional beam are offered and suggestions on modernization of the frame frame structure are proposed in order to reduce the load on the traction motor mounting sites and increase the reliability of their work. The introduction design of the modernized fastener electric locomotive allows to increase the dynamic qualities of their structures in operation and allows to simplify the technology of installation of traction engines, which greatly simplifies their repair.
