Temperature control of traction electric motors running on direct current with the help a modern microprocessor-based locomotive system is analyzed in paper. Development methodology for calculating temperature windings operating current, based has been discussed. To determine dependence motion profile and weight rolling stock.

The locomotive assignment and the freight train scheduling are important problems in railway transportation. Freight cars are coupled to form a freight rake. The freight rake becomes a train when a locomotive is coupled to it. The locomotive assignment problem assigns locomotives to a set of freight rakes in a way that, with minimum locomotive deadheading time, rake coupling delay and locomotiv...

[Purpose] This study aimed to examine the prevalence of locomotive syndrome among patients with obstructive sleep apnea syndrome (OSAS) using the "loco-check" recently developed by the Japanese Orthopedic Association, and to compare health-related quality of life (HRQOL) among patients with and without locomotive syndrome. [Subjects and Methods] This cross-sectional study evaluated 1,195 outpat...

Locomotive syndrome is a condition of reduced mobility due to impairment of locomotive organs. Since upright bipedal walking involves minutely controlled movement patterns, impairment of any aspect of the locomotive organs has the potential to adversely affect it. In addition to trauma, chronic diseases of the locomotive organs, which progress with repeated bouts of acute exacerbations, are com...

BACKGROUND The Japanese Orthopedic Association first proposed the concept of "locomotive syndrome" in 2007. It refers to circumstances in which elderly people need nursing care services or are at high risk of requiring such services within a short time. Recently, the public health burden of providing nursing care for elderly individuals has increased. Therefore, locomotive syndrome, and the mea...

This paper deals with the lateral force effects of conventional four-axle railway vehicles in conditions S-shape curves, which are represented especially by switches negotiated diverging direction. With use a multi-body model an electric locomotive, sensitivity analysis selected vehicle parameters on maximum guiding S-curve is performed. Subsequently, definition so-called equivalent proposed. s...

The article considers methods for studying torsional vibrations of the wheel-motor block a diesel locomotive UZTE16M. locomotives in question were modernized at structural enterprise “O’ztemiryo’lmashta’mir” (Machine building and repair Uzbekistan Railways company) under joint-stock company “O’zbekiston temir yo’llari” (Uzbekistan railways). authors developed dynamic model analysis vibrational ...
