液压仿真精度研究

Investigation into accuracy of hydraulic emulation

本文运用计算机仿真理论和误差理论,论证性能仿真技术对工程设计的极好指导意义,特别在方案设计、参数选择、性能优化等方面的独到优势。同时又对仿真过程中各环节产生的模型误差、参数误差、截断误差和舍入误差进行分析和讨论,从而提出现有液压仿真技术尽管一般不能得到十分精确的定量结果,但可以得到用于指导实践的定性结果。只有正确地认识性能仿真技术,才能更好地利用这一技术为工程设计服务。

This paper proves guiding meaning of, performance emulating technique to engineering design by using the theory of computer emulation and error theory, analyzes and discusses the model, parameter, cutoff, round-off errors, and puts forward the hydraulic emulation technique with achieving qualitative result and guiding practice.
