数模的 meaning in Chinese
digital-to-analog
Examples
- The computing results show that the current hi the outfall reach moves periodically because of the sea tide , but the influence decrease upstream
数模的计算结果表明，淮河入海水道河口段水流受潮波影响呈周期性变化规律，但其影响程度从河口往上游逐渐减少。 - The main work of this paper is establishing the 3d model of the whole bus body and implementing the strength analysis , stiffness analysis , modal analysis and road surface spectrum analysis , synthesized considering the geometric properties , physical properties , material properties . the appraisal to the mechanics performance is produced . the suggestion of the structure improvement is put forward based on the analysis result and is adopted by nanjing iveco company
本文主要工作是综合考虑对象的几何特性、物理特性、材料特性,进行了整车三维数模的建立;实现了nj6826tmf车的车身强度分析、刚度分析、固有频率振型分析和路谱分析,在结构的力学性能上给出了相应的评价;根据分析结果,提出结构改进建议,并得到南汽的采纳;对该车的超重问题,以轻量化为目标,提出使nj6826tmf轻量化的设计方案,供南汽参考。 - The principle of the predigestion in geometry modeling is omitting the function part and the non - load - carrying process structure , and to the big and transition arc , the curve is replaced by straight line using the thought of curve and free - surface segmentation . the physical characteristic of the digital model reflect on remaining the main mechanical characteristic of the objects . the shell element model is used in strength analysis , stiffness analysis and dynamic analysis
文中几何建模的简化原则是,略去功能件和非承载的工艺结构,对于大圆弧和过渡圆弧,以曲面分块和曲线分段的思想进行适当的以直代曲;数模的物理特性反映在最大限度地保留对象的主要力学特性;在强度、刚度和动态分析中采用壳元模型,轻量化设计中采用梁元模型;材料特性根据所用材料定义其主要性能参数。
