The determination of the dynamic loading bearing structures main types freight wagons with actual dimensions under operating conditions is carried out. inertial coefficients are determined by constructing their spatial models in SolidWorks software package. Two cases – vertical and longitudinal planes have been taken into account. studies were out a flat coordinate system. When modeling wagons,...

Emniyetli ve ekonomik yük treni işletmeciliği için vagonlarının bakımı önemlidir. Bu çalışmada 2019 2022 yılları arasında bakım verilerinin bulunduğu listeden farklı açılardan analizler yapılmıştır. analizlerdeki amaç demiryollarında sahip olunan kısıtlı iş gücü nedeniyle verimli bir planı önceliklerin belirlenmesidir. Verilerin istatistiksel analizi ile en çok görülen arıza tipleri belirlenmiş...

This paper presents a closed loop simulation model that represents the mining logistics chain of the Vitória Minas Railway (VMR), Brazil. The simulator includes the loading process, circulation of loaded trains, unloading of ores for external and internal markets and the distribution of empty trains for new loads. General cargo and passengers trains are also included in the model, which, along ...

This report presents theoretical estimates of the Power Density levels which may be reached inside trains. Two possible sources of high levels of radiation are discussed. The first one arises since the walls of the wagons are metallic and therefore bounce back almost all radiation impinging on them. The second is due to the simultaneous emission of a seemingly large number of nearby telephones....

There have been numerous attempts and investigations carried out with the objective to reduce noise generated by railway freight wagons because is one of ever-present negative environmental pollution phenomena. This resulted in strong legislation requirements on reduction transport, case wagons, only exterior a problem. However, extremely hard metal structures running rails naturally generate h...

For many years, on-farm yield evaluations of corn (Zea mays L.) hybrids were done with weigh wagons, handheld moisture testers, and measuring wheels. Today, most combines have continuous flow yield and moisture sensors. Published research results comparing the accuracy of combine-mounted sensor systems with that of weigh wagons are limited for on-farm corn hybrid evaluation. This study examined...
