Co-simulation of Offshore Skid-mounted Fracturing Equipment Based on ADAMS and ANSYS

The periodic excitation of the offshore skid-mounted fracturing equipment is prone to cause damage to its bottom support during the operation on offshore platform or deck.To address the issue,dynamic simulation analysis on the main excitation source of skid-mounted fracturing equipment-five-cylinder reciprocating piston pump has been conducted.The analysis showed that the largest exciting force generated in the second gear,so that the second gear was set as an analysis example.The dynamic simulation analysis of skid-mounted fracturing equipment under different connection schemes has been conducted by using ADAMS.The results showed that the exciting force is smaller and stable when the skid-mounted fracturing equipment was supported by eight elastic supports.The results of dynamic response of eight elastic supports is put into ANSYS as the deck’s dynamic responses,the results showed that the deck’s dynamic responses could meet the merchant deck vibrating comprehensive evaluation criteria.The vibration system for offshore skid-mounted fracturing equipment could provide a certain reference value.
