The crankshaft is very important in high-power drilling pump. The information on the vibration mode and
frequency response is critical for the crankshaft to work normally in drilling pump. ANSYS finite element analysis
software was used to implement the modal analysis of the crankshaft thus obtaining characteristic frequency and the
corresponding vibration mode and then by the harmonic response analysis which was carried out based on the modal
analysis, dynamic response of the crankshaft was obtained. The result shows that the working speed of crankshaft
can avoid the region of sympathetic vibration effectively, no resonance will happen. The strength and fatigue life of
crankshaft are also checked according to the stress results. The analysis also makes a base for the optimized design
of dynamic performance of the crankshaft.
Key words: ANSYS, drilling pump, dynamic response, fatigue life, harmonic response, ,
