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 ...

Purpose: The importance of developing automatic speed control systems for hump-shunting diesel locomotives is demonstrated. Using as an example a shunting locomotive Type TEM7A mathematical description provided electric power transmission final controlling element the system and train object. A flow-chart generated system’s principle operation designed so to ensure main requirements are met. PI...

The article considers the possibility of using finite element method for strength calculations nodes and parts modern locomotives. There are examples solid-state models construction bogie frames in SolidWorks software package. Developed finite-element allow determining tense-strained state elements crew part final outcome modeling is stress distribution diagrams locomotive frame. data obtained ...

En genel tanımıyla baga (supap yuvası), içten yanmalı motorlarda silindir başlığında bulunan, supap oturma yüzeyiyle temas ederek sızdırmazlık sağlayan önemli bir motor bileşenidir. Hem egzoz hem de emme supaplarının işlevini doğru şekilde yapabilmesi için bagaların da kusursuz çalışması gerekir. Supap ve baganın yüzeylerinde meydana gelecek hasar çalışma performansını etkilemektedir. Ağır yük ...
