| 摘要:以某型特种发动机为研究对象，采用ADAMS软件建立了其传动系统的刚柔混合多体动力学模型，并对边界条件和相关计算进行设置。通过有限元模态分析和试验模态分析相结合，验证了曲轴柔性化处理的正确性。在该传动系统动力学特性的计算分析中考虑了齿轮啮合冲击力对主轴承受力的影响，得到了较为准确的动力学特性。 |

| Abstract:The rigid and flexible multi-body dynamical model of the transmission system for a special engine was built using ADAMS software, and the boundary conditions were set and relative calculations were carried out. Through FEA modal analysis and experimental modal analysis,the flexible process of crankshaft was verified. The influences of the gear meshing impact on the main bearing loads were taken into account during the calculation analysis of dynamic characteristics of the transmission system, and relatively accurate transmission system dynamic characteristics were obtained. |
| Key words: special engine transmission system dynamic characteristic gear meshing impact |
