Shock Resistance of a Marine Pump
Numerical method is used to build the entity model and finite element model of a marine pump,modal analysis shows that modal frequency is not equal to the operating frequency and the resonance is not produced in the pump.The finite element method is used to calculate the shock load which is the request of GJB.The allowable strength at vertical,longitudinal and horizontal direction of the pump is analyzed,and the anti-shock behavior of the pump is checked too.The results show this type pumps are not destroyed wholly and can be working normally in the shock environment,which satisfy the requirements of GJB.But the bracket position of the pump is suffered great compressive stress which leads to the designed and strengthened again.
