| At present, wave model tests are widely used in the coastal and marine engineering research. Wave simulation in laboratory can provide reliable test data. It plays an important role in the engineering design and scientific experiments.Based on the multi-directional wave maker in Tianjin University Marine and Offshore Engineering Laboratory, its wave basin is 60m in length,40m in width.1.2m in depth, Visual C++ is used as the development platform, The main user interface is created by single document file based on MFC. In accordance with the parameters of different interfaces, public variables are set and different functions are complied, and the sequence algorithm procedures are realized. This software can simulate various forms of waves, including regular waves with different parameters, irregular waves are simulated by various spectrums, and the directional function can be chosen. The software also can simulate wave groups by different group factors and non-linear waves. CSocket class is used in data communication, CSocketFile class and CArchive class are chosen to realize the process while setting variables as the network order. Network communications and data transmission between host computer and two lower computers can be implemented. The wave maker's operating states can be observed by network. Acquisition data can be for statistics. The software also can be used in spectrum analysis and direction analysis.Some performance tests about the wave maker have been done. Regular wave qualities are evaluated. Real spectrums and ideal spectrums are compared to get the errors of irregular waves. The ranges of max wave heights and wave periods are got in different water depths under the existing conditions.By the 3D wave model test of Wei Hai shipyards relocation, wave tests are made and wave data are acquired in different water levels, including oblique regular wave and irregular wave. Based on the experimental acquired data, some suggestions are given on the breakwater project.
