Abstract
With more and more attention being paid to anti-shock of the warship by many country’s navy, it is of practical significance to study the anti-shock characteristic of the diesel engine which belongs to the A class facility on warship. Owing to the high price of shock test, simulation combined with partial shock test methods are adopted by many countries to ensure the facility’s anti-shock performance. A numeric virtual platform of TBD234V6 diesel engine generator set is built by means of software MSC.ADAMS and four machine feet of the diesel engine are modeled flexibly. The virtual shock test of the generator set is conducted on this platform according to the German shock standard BV043/85 and anti-shock performance limits of the machine feet is obtained. Hammer experiment is also carried out on the real generator set. After the comparison of the simulation results and the experiment results, the deficiency aspects need to be improved are pointed out at last.
