Design analysis and manufacture of a variable load effective wear machine

Abstract

A variable load effective wear machine was designed, analyzed using the finite element method, and manufactured after its strength was verified. The creation of the solid design model and the finite element analysis were performed in the SolidWorks program. In the wear machine, the abrasive, attached to a plate that can move linearly back and forth, is in contact with the surface of a material to be tested in a fixed position. In the system, the movement is repeated periodically twice in each cycle. The operation of the design system is explained by the calculation of the reaction force and strength under different loads, depending on certain settings. The wear machine was able to operate successfully for a maximum of 30 N loads and up to 30 min in the wear tests. Compared to linear motion wear machines operating with constant speed and a constant load effect, the manufactured wear machine can better explain the wear mechanism between contact materials as a "constant load-variable load effect".
