In response to the issue of slamming loads experienced by ship structures under high sea conditions, this paper employs the Abaqus finite element software to simulate the impact of slamming loads moving in different directions on the dynamic response of five stiffened panels. The slamming load is equivalently modeled as a pulse time history that rises linearly and decays exponentially. By varying the load parameters (peak pressure, low pressure, length of rising section, length of falling section and moving speed), the paper analyzes the specific impact of these parameters on the dynamic response of the stiffened panels. The research finds that the dynamic response of the stiffened panels is closely related to the load parameters, especially the influence of moving speed on the dynamic response is the most significant. Furthermore, by introducing the moving dynamic load factor DLFm and conducting a dimensionless analysis, the paper deeply explores the variation laws and sensitivities between the dynamic response and the dimensionless parameters of the slamming load, providing important theoretical basis for the design and optimization of ship structures.

The full-scale measurement has become an important approach to acquire the ice loads due to the lack of the actual ice condition and the corresponding prediction methods for the ice loads acting on the hull. Abundant research achievements have been recently obtained in the full scale measurement with the building of more polar ships and their navigation in ice area. A systematic review is presented about the researches on the full-scale measurement of ice loads worldwide since 2015, including the measured data and methods of full-scale measurement, the methods of converting the full-scale measurement data to ice loads, the factors affecting ice loads and the spatial distribution characteristics, the probability models of ice loads and the prediction methods for the extreme design values. Finally, the main research conclusions of the full scale measurement of ice loads are summarized to provide important reference for the research of ice loads. It is also pointed out that more data accumulation and theoretical discussions are still needed for the application of the extreme ice load prediction methods in the design of full-scale ships.
