利用仿真技术对古代水力机械的复原实验

Simulations of the mechanics of ancient hydraulic machines

对中国古代水力机械发明创造的研究,过去主要采用实物考证和文献考证的方法。这些方法对于那些已不复存在的机械,有很大的局限。该文将计算机仿真技术引入古代机械研究领域,采用CAD软件U n igraph ic建模并导入仿真软件ADAM S(au tom atic dynam ic ana lys is ofm echan ica l sys-tem)进行水运仪象台动力学模型的仿真实验。实验结果表明,在工作机输出端脉冲曲线和针对每个部件的仿真数据符合水运仪象台的实际运动状况,利用上述计算机仿真技术进行古代机械的复原实验是可行的,实验结果将对古代机械的复原提供有价值的参考数据。

Many great hydraulic machines were invented by wise scholars in ancient China. Previous research on these machines has only analyzed some relics and descriptive texts, so the working principles and the actual designs of the now lost ancient machines r can not he understood. This paper analyzes an ancient astronomical clock tower with a CAD software model transferred into the simulation software ADAMS. These simulations of the ancient machine provide a new tool for not only studying the astronomical clock tower, but also for studying various other ancient Chinese machines using modern computer technology. The simulation results provide valuable data for ancient Chinese machine reconstruction.
