离散误差 meaning in Chinese
discretization error
Examples
- Based on the simplified principle , the modal shapes of selected structural modes are converted into modal strains . to minimize the calculation error , curve - fitting technique is used in the process . the modal strains are summed together to determine the global distribution of the structure for selected vibration modes so that the position of piezoelectric elements could be optimally determined according to the simplified optimization principle
通过二阶中心差分运算将模态振型转化为模态应变，采用应变曲线拟合方法降低离散误差，进而将各阶待控模态应变进行叠加，获取系统整体特征应变分布情况；最后根据压电元件位置优化的简化目标函数，将压电片的最优位置确定为柔性板叠加模态应变的极值区域。
