Track Irregularities Stochastic Modeling
High speed trains are currently meant to run faster and to carry heavier loads, while being less energy consuming and still respecting the security and comfort certification criteria. To face these challenges, a better understanding of the interaction between the dynamic train behavior and the track geometry is needed. As during its lifecycle, the train faces a great variability of track condit...
متن کاملTrack Irregularities Stochastic Modelling
This paper presents a methodology to build representative railway track geometries thanks to a stochastic modelling. This modelling, which has to integrate the statistical and spatial variabilities and dependencies, is a key issue when using simulation for conception, maintenance or certification purposes, as the dynamic behaviour of the trains is mainly induced by the track geometry. The stoch...
متن کاملModeling and Simulation of Shanghai MAGLEV Train Transrapid with Random Track Irregularities
The MAGLEV Transrapid is a kind of new type high speed train in the world which is levitated and guided over the track using electro magnetic forces. Because the electro magnets are unstable, they have to be controlled. Since 2002 the worldwide first commercial use of such a high speed train based on German technology is running successfully in Shanghai Pudong Airport, P.R.China. In this paper ...
متن کاملInvestigating on the Effects of Random Irregularities of Railway Track by Half-Bogie Model
The vibrations produced by trains include two parts which are deterministic and random vibrations. Due to variation of dynamic loads and patterns of load-time, the random vibration of moving train is one of the most important issues in the field of railway engineering. One of the important sources in producing the train vibrations is rail roughness and irregularities. In this paper, responses o...
متن کاملan investigation about the appropriate stochastic modeling framework for agricultural insurance pricing
با توجه به اینکه بیمه محصولات کشاورزی در ایران بیشتر جنبه ای حمایتی دارد و خسارات گزارش شده عموما بیش از حق بیمه های دریافت شده است، در این پایان نامه به جهت تعیین قیمت بیمه محصولات کشاورزی (گندم دیم) از فرآیندهای نوفه شلیک به عنوان مدلی مناسب استفاده شده است. بر اساس داده های صندوق بیمه کشاورزی از خسارات اعلام شده در سال زراعی 1388-1389 گندم دیم، در این پایان نامه حق بیمه خالص و ناخالص این محص...
