Description

technical field [0001] The invention belongs to the field of ships, and relates to a ship simulation test system, more specifically, to a digital simulation-based simulation test system. Background technique [0002] Hydrodynamic performance is an important basic common technology in the shipbuilding industry and the core basis of the overall design of ships. Comprehensive hydrodynamic performance evaluation is an essential and important content in ship research. In recent years, fluid mechanics technology has played an important role in the design and evaluation of ship comprehensive hydrodynamic performance. With the rapid progress of global ship hydrodynamic application technology, the research on ship virtual tank is an inevitable trend. At present, there are a large number of physical water tanks used for the test and research of ship performance, but the traditional physical water tanks have high economic costs, long test time and high cost, and cannot complete the te...

[0004] However, when the existing digital simulation test system evaluates its performance and functions, the evaluation method adopted, especially the weight determination method of each evaluation index used in the evaluation is unreasonable, which often leads to large deviations in the evaluation results. Thus affecting the simulation test results and the subsequent optimization design
