Based on the tribo-dynamics model established and numerical solution method for the guide shoe-guide friction pair in low-speed marine diesel engines, the effects of guide shoe-guide clearance, lubricating area, guide shoe profile, crankshaft offset, and crosshead pin offset on the tribo-dynamics of guide shoe are analyzed. The results show that increasing the clearance between guide shoe and guide plate can reduce the loss of friction. However, it can significantly increase the maximum slap energy of guide shoe, which exacerbates the engine vibration and noise. Offsetting the crankshaft axis towards the main thrust side reduces the side force after top dead center and the friction loss of guide shoe. The maximum slap energy in a working cycle can also be reduced. However, offsetting the crosshead pin to the main thrust side increases side force after top dead center and the friction loss of guide shoe.
