Reciprocating attachment for rotary wear testing machine

Developing the project involved designing concepts, calculating dimensions, fabricating parts, and assembling them with copper specimens. The design calculations consisted of assuming maximum loads on the structure, calculating MS Plates and EN8 plate dimensions, deciding the structure's height to level the wear testing machine with a Milling slot in the block, and calculating torques for both the wear testing machine and its resisting attachment. Exceeding torque forces caused reciprocating actions, prompting further calculations of the connecting rod's cross-sectional area using force data from the torque at the machine end. This resulted in determining maximum stroke lengths. Notable considerations included checking for failure cases along the slot and treating the connecting rod as a knuckle joint for assessment purposes. A 45kg Standard slider from Godrej was utilized, though its thickness was only represented in CAD modeling, serving as a key reference point for structural design verification.
