<![CDATA[This research focuses on the design and simulation of a brush sander machine shaft with a two-shaft brush type. The machine shaft is a critical component in a brush sander machine, and efficient design is the key to improving machine performance and durability. Simulations were carried out to analyze the distribution of force, torque, von Mises stress, deformation and safety factors on the shaft. Ductile Iron is used as the shaft material with a yield strength of 5.51485e+008 N/m^2. The brush model 2 simulation results show a maximum Von Mizes Stress of 2.955e+002 N/m^2 and a minimum of .709e+000 N/m^2. Maximum displacement is .567e-008 mm and minimum is 0.000e+000 mm, with the highest value at the shaft end in red. Simulated maximum strain 1.151e-009 and minimum 5.726e-011. The maximum factor of safety (FOS) is 1.171e+008 and the minimum is 1.866e+006, indicating a safe model with criteria below 10. This research provides in-depth insight into the mechanical characteristics of the shaft, allowing designers to make design adjustments to improve the efficiency and reliability of brush sander machines with two brush shafts.]]>
