Effect of Process Parameters on Friction Model in Computer Simulation of Linear Friction Welding
The friction model is important part of a numerical model of linear friction welding. Its selection determines the accuracy
of the results. Existing models employ the classical law of Amonton-Coulomb where the friction coefficient is either
constant or linearly dependent on a single parameter. Determination of the coefficient of friction is a time consuming
process that requires a lot of experiments. So the feasibility of determinating the complex dependence should be
assessing by analysis of effect of approximating law for friction model on simulation results
A 2D Computer Model of Cutting of the A2024 Aluminum Alloy
Machining can have a significant effect on the properties of machined parts of different equipment during their
production. This paper is on the effect of vertical angle and cutting speed on temperature and stress. Using computer
modeling values of these parameters were identified. Using the least squares method and a factorial computer experiment
the dependence of peak values of temperature and stress is shown
On the visualization of joint formation during linear friction welding
A 3D computer model of the preliminary and the transition phases of LFW using ANSYS was developed. Based on the
adhesion phenomena theory, we introduce a simple method to evaluate the areas of joint formation. Results of this
evaluation are in good agreement with experiments. Custom software for the 3D-simulation of the process of joint
formation and material movement into the flash was built, which used the results of the FEM model
