ARTICLE ANNOTATION

quote
This article carried out an analysis of the choice of the type of wagon as the worst runner, taking into account poor conditions when calculating the height of the Sorting hill. The movement of the gondola car descending from the Sorting hill has been analyzed. The classification of forces acting on a gondola car is fully illuminated. The aerodynamic pressure and displacement distance calculation work that was affecting the front and inner rear wall of the gondola car was carried out under the influence of the counter-blowing airflow. When the speed of movement of closed and gondola cars on the Sorting hill is compared, it can be seen that as a result of the change of the accelerator plot of the Sorting hill, the speed of the gondola car at the end of the accelerator plot was found to be 34.6% lower than that of the closed wagon. Results were obtained using SOLIDWORKS Flow simulation package software in assessing the impact of the wind speed experienced, which ensured a further increase in the accuracy of the results. The maximum aerodynamic pressure of the airflow affecting the wagon is 101,602 KPA. In the processes for calculating the height of the Sorting hill, the effect of the air flow affecting the gondola car only on the front was taken into account however, the turbulent air flow generated within the empty gondola car and the occurrence of aerodynamic effects on the wagon's final transverse wall were noted in the modeling processes.
