Investigation of Strength and Calculation of Wear Resistance of A Quick-Release Mechanism in Connection With The Working Attachment of A Hydraulic Excavator

In this study, a model of a quick-coupler device is investigated and presented within simulation modeling software. A method is presented that enables the design and construction of a simulation model of a quick-release device as an alternative to physical modeling for further investigation. The predicted service life of the tested quick-coupler model is estimated based on the S-N curve (fatigue curve). The S-N curve illustrates the relationship between stress amplitude and the number of cycles to material failure.
