Abstract
Perpose of research.The extreme working conditions of the elements of modern designs, the complexity of their shape and large dimensions make it extremely difficult and expensive to carry out a full-scale or semi-natural experiment, especially when it comes to establishing ultimate (breaking) loads, therefore, in strength calculations, it is necessary to resort to numerical methods, which include the finite elements method. The finite elements method is not limited by either the form of the structure or the method of applying the load. The most critical part of the design is welded joints. There are frequent cases when the structural failure occurred in the field of welding. In this regard, this work is devoted to the stress analysis arising during loading in welded joints of pneumatic cylinder.
Methods.This article uses finite elements analysis of welded joints of a pneumatic cylinder in the APM FEM software package.
Results. The research results presented in the article show that the stress pattern in welded joints differs in different sections and arrangement in the structure.
Conclusion.The use of the finite elements method allows us to evaluate the stress pattern in a welded joint in a particular section and to select the necessary design and rationally position the welded joint.
