Abstract:The manufacturing of a composite material out of aluminium (Al) and yttrium oxide (Y2O3) was achieved via the use of the microwave hybrid sintering method, which is an energy-efficient and eco-friendly production process. Compression and dry reciprocating wear tests are conducted on the manufactured material to learn more about the function of reinforcing particles in composites. The exothermic temperature marginally shifts (1 °C) when Y2O3 reinforcement is added to the Al matrix. The average micro hardness of… Show more
“…Later, various authors [36][37][38][39][40][41][42][43] investigated the effects of preload, surface roughness, rotational speed, manufacturing methods, and lubrication on the wear behavior of bearings using numerical models. Bhoi and Singh [44] performed dry sliding wear tests by using weight loss techniques to estimate the wear rate for Al-Y 2 O 3 based composite material.…”
An overrunning clutch, generally known as a freewheel clutch, is a direction dependent torque transmitting device that works on the principle of wedge friction. The overrunning wear characteristics of freewheels are studied using pin-on-disc tribometry. The wear experiments for freewheels are performed at accelerated loads to promote wear in a short period. The overrunning wear life of the clutch under operating conditions is predicted using an appropriate load-life relationship. A finite element-based Archard’s wear model is implemented as a numerical strategy to evaluate the wear profile. The maximum local wear for various loads is computed using experimentally obtained wear and friction coefficients. The numerical simulation is performed with an adaptive mesh technique utilizing incremental nodal displacements to predict surface wear. The experimental and numerical results are compared in terms of wear characteristics. The numerical wear results are almost 11% higher than the experimental results. The wear life of an overrunning clutch is predicted in terms of overrunning speed based on the wear amount.
