Freight-train derailment rates for railroad safety and risk analysis.
Derailments are the most common type of train accident in the United States. They cause damage to infrastructure, rolling stock and lading, disrupt service, and have the potential to cause casualties, and harm the environment. Train safety and risk analysis relies on accurate assessment of derailment likelihood. Derailment rate - the number of derailments normalized by traffic exposure - is a u...
متن کاملModelling the longitudinal dynamics of long freight trains during the braking phase
The common use of UIC Pneumatic braking plant in long freight trains may involve time delays in the application of the braking forces along the convoy. This variable braking action along the train may cause heavy longitudinal efforts that could lead to wagons damaging and even cause train derailment. Simulations of these phenomena are very important both for safety and economic reasons since lo...
متن کاملOn the dynamics of European two–axle railway freight wagons
The design of European two–axle freight wagons can be traced back to the 1890’es. It has been and still is widely used in Europe because it is simple, rugged and cheap in price and maintenance. The internationally approved suspension for two–axle freight wagons in Europe is known as the UIC standard suspension (see Fig. 1). Each wagon has four of these suspensions. They consist of a leaf spring...
متن کاملAnalysis of U.S. freight-train derailment severity using zero-truncated negative binomial regression and quantile regression.
Derailments are the most common type of freight-train accidents in the United States. Derailments cause damage to infrastructure and rolling stock, disrupt services, and may cause casualties and harm the environment. Accordingly, derailment analysis and prevention has long been a high priority in the rail industry and government. Despite the low probability of a train derailment, the potential ...
متن کاملinvestigation of effective parameters on the rigidity of light composite diaphragms (psscb) by fem
در این رساله با معرفی سقف های psscb متشکل از ترکیب ورق های فولادی ذوزنقه ای و تخته های سیمانی الیافی به عنوان سقف های پیش ساخته (سازگار با سیستم سازه ای قاب های فولادی سبک) به بررسی پارامترهای موثر بر صلبیت سقف، پرداخته می شود. در تحقیق حاضر ابتدا به مدل سازی دو نمونه سقف آزمایش شده، به روش اجزاء محدود با استفاده از نرم افزار تحلیلی abaqus ver 6.10 پرداخته شده است. نمونه های ساخته شده تحت اعما...
