Purpose: The main issue of this paper is to present results of strength and fatigue limit analysis applied to piston type hydraulic cylinders. It will also shows advantages of application of the up-to-date digital chain of engineering analysis within which CAD tools are being used as well as strength and fatigue limit analysis. Design/methodology/approach: Computer analysis of the strength analysis by using Finite Element Method (FEM) and fatigue life analysis by using Fatigue Life Prediction Method (FLP) were carried out. Findings: The most strenuous and at the same time opened to a damage risk cylinder zones were localized. Two construction solution possibilities of fixing the tongue stub with a hydraulic cylinder jacket were analysed. Finally Wöhler fatigue graphs for a different values of operating average pressure and stress concentration factor were presented. Research limitations/implications: Further researches should concentrate on modifications and analysis which will help to recognize the best possible zones of fixing a tongue stub with a hydraulic cylinder jacket in order to find the best configuration of construction kinematic pair. Practical implications: Modern engineering construction analyze require not only standard strength analysis but also calculation of fatigue life. Originality/value: The paper can be useful for person who performs strength analysis with a use of finite element method but has never used digital fatigue life analysis method. It might be also useful for a person interested in recognizing of both methods.
