Anti-shock capacity of marine diesel power plant is very important for the survival of modern navy ships. Ship’s shock testing is an effective approach to study the anti-shock competence of the plant. In this article, the shock testing technique of marine diesel power plant is studied. The selection of test parameter, sensor installation, construction of test system and data processing of the diesel power plant are discussed. Finally, the shock testing method of marine diesel power plant is summarized. The result of this study can be applied to the shock test of some other marine equipment.

Affect of Displacement Restrictor on Shock Resistance Performance of Double-stage Vibration Isolation System
MA Bing-jie;SHEN Jian-ping;WANG Zhi-gang
   2011, 31 (6): 72-75.   DOI: 10.3969/j.issn.1006-1355-2011.06.016

With the given shock actions, the displacement response of the equipment with vibration isolation mounting may exceed the deformation limits of outside pipelines, and even exceed the deformation limits of isolators themselves. Therefore, displacement restrictors should be used in order to limit the relatively large displacement without acceleration response increasing. In this thesis, the double-stage vibration isolation system is researched, displacement restrictors is simulated with nonlinear springs, the shock responses is analyzed using direct integral method, and the affects of parameters (stiffness and gap) on isolation mounting performance is discussed. Finally, a significant conclusion is summarized.
