摘　　要：应用Stewart机构模拟船舶在波浪中的不规则摇荡,首要任务是获得机构六通道的输入轨迹。针对这一问题,以模拟船舶的不规则横摇运动为例,将船舶运动谱分析方法与并联机构反解理论相结合,提出了一种输入轨迹的生成方案。将生成的输入轨迹输入到船舶模拟器实验平台中进行试验,试验结果表明,所得输入轨迹可以实现Stewart机构对船舶不规则运动的模拟,验证了该方案的可行性,并为模拟船舶不规则摇荡的后续工作奠定了基础。When applying Stewart mechanism to simulate the ship＇s irregular swaying in the wave, the primary task is to acquire the input track of six paths in the mechanism. As to the issue, the irregular rolling motion of the ship simulator is taken as an example to figure out the input track of the mechanism by combining the ship motion spectral analysis method with parallel mechanisms inverse solution theory. The input track enters the ship simulator experimental platform to be tested, and the results of which suggest that the input track can complete the simulation of the ship＇s irregular motion by Stewart mechanism. It verifies the viability of the program and lays the foundation for further work on simulating the ship＇s irregular swaying.
