INFLUENCE OF DESIGN FEATURES OF RELOADER WELDED ASSEMBLIES ON ITS PERFORMANCE.

Improvement of reliability and safety of structures of machines and mechanisms in long-term operation under cyclic loading is becoming ever more urgent. Welded assemblies of a reloader were taken as an example for analysis of design solutions for the above assemblies allowing for their load level. Special attention is given to questions of decreasing structural stress raisers of weldments. An improved design of reloader diaphragm assembly, as well as geometry of electrotrolley edge preparation were proposed, ensuring the high quality of welded joints and, therefore, the required fatigue life.
