Abstract

Abstract

The drop safety of marine equipment is of paramount importance in daily operational tasks. To assess the safety of a full-size drop of a certain type of equipment, a finite element simulation model of the overall structure was established using LS-DYNA software. The numerical simulation and analysis of the horizontal drop from a height of 5 meters were conducted to obtain the impact response characteristics of the energetic material and each compartment. The results show that under 5-meter drop conditions, after multiple rebounds, plastic deformation occurs within the materials of each compartment. The maximum stress of the energetic material is located at the corresponding position in the cavity at the collision point between the structure and the ground. When the local pressure inside the energetic material exceeds its yield strength, deformation occurs. Although no ignition reaction happens during the entire collision process, the internal stress, temperature, and reactivity values of the energetic material show slight fluctuations, and minor local chemical reactions occur. A verification test of the 5-meter horizontal drop using a full-size structure is conducted. The experimental results are consistent with the simulation results, confirming that the structure does not ignite or explode. This study can be applied to the safety analysis and assessment of full-size drops for other marine equipment and can effectively guide the safety design and engineering development of such systems.
