Problems solved by technology

[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

Embodiment Construction

[0068] The present invention will be further described below in conjunction with the accompanying drawings and examples, and the contents of the examples are not intended to limit the protection scope of the present invention.

[0069] At present, the research on ships is mainly the research on their hydrodynamic performance. The research on the hydrodynamic performance of ships is the basis of comprehensive navigation performance of ships, and it is also one of the important problems to be solved in the research and development of new ships and ocean engineering. Model test is a very important research method in modern ship research. The use of ship physical tank tests is often limited and affected by scale effects, blocking effects, smooth disturbances, and measurement accuracy, and the test period is long and the cost is high, making it difficult to optimize the design, which is not conducive to the development of innovative ships with superior comprehensive performance. In...

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...
