The rail is just a set of connected points. Touching the line places the character on the closest position on top of it and activates the animation. As the time passes, the character gets moved downwards with an acceleration proportionate to the line's inclination. 4 Likes. sonihi (sonihi) May 29, 2019, 11:17pm #5.

Best practice rail grinding is always preventive grinding which is designed to remove just enough metal to prevent the initiation of rolling contact fatigue (RCF) and to maintain …

Preventive Grinding. During preventive grinding, rail faults such as head checks, corrugation and wave formation or excessive profile deviations are dealt with when they first start to appear. This is achieved by removing the hardened and brittle rail surface – a process that requires only relatively limited cutting depths and fewer running ...

Post-grinding rail roughness level has a big impact on the performance of the rails. For cases where roughness values were particularly low, flange-climbing derailments occurred [6, 7], when a wheel of a rail vehicle climbs up a rail.The names used for relevant parts of wheels and rails and a typical sequence of events leading to a flange …

INTRODUCTION OF RAIL GRINDING ON INDIAN RAILWAYS – AN EMPHASIS ON PRE, DURING AND POST GRINDING ACTIVITIES By Sri. M.R.K.Raju, Chief Instructor, …

Grinding machines or tools use an abrasive wheel to remove metal from the workpiece. When the wheel rotates, it cuts material off the workpiece by cutting. The amount of material removal is dependent on factors like abrasive material and grit selection. The video below explains how to select the right abrasive.

Based on more than 25 years of experience, the conviction of the necessity of preventive rail grinding is strong in the Netherlands. Preventive grinding leads to a significant increase in the service life of rails, a delay in the occurrence of corrugation, and a decrease in traffic noise levels. The article looks at the grinding strategies, past and present, on …

A typical rail grinder doing work along a heavy, freight main line in the United States is not a singular unit but an entire train staffed with several workers. It includes the lead locomotive, which pulls the grinding equipment and crew quarters. A typical grinder is stocked with enough tools, equipment, and amenities for the crew to be out on ...

Thus, for a 96 stone grinding train with 48 motors per rail, it is necessary to analyze the full sequence of 48 motors as each motor individually and sequentially removes metal from the rail head. Furthermore, this analysis must be sensitive to key factors, such as grinding speed and the key pattern parameters of motor angles, sequence and power.

Comparison of pre- and post-grind rail profiles shows that a large production grinder can remove as much as 0.014 inch per pass at slow speeds and 0.006 to 0.008 inch per pass at more typical speeds, Cummings said. "Based on these values, three to five grinder passes could have completely eliminated the majority of cracks and …

Non-uniform rational B-spline (NURBS) curves are combined with the Kriging model to present a prediction method of the rail grinding profile for a grinding train. As a worn rail profile is a free-form curve, the parameterized model of a rail profile is constructed by using the cubic NURBS curve. Taking the removed area of the rail profile cross …
