A fast compound direct iterative algorithm for solving transient line contact elastohydrodynamic lubrication (EHL) problems is presented. First, by introducing a special matrix splitting iteration method into the traditional compound direct iterative method, the full matrices for the linear systems of equations are transformed into sparse banded ones with any half-bandwidth; then, an extended Thomas method which can solve banded linear systems with any half-bandwidth is derived to accelerate the computing speed. Through the above two steps, the computational complexity of each iteration is reduced approximately from O(N3/3) to O(β2N), where N is the total number of nodes, and β is the half-bandwidth. Two kinds of numerical results of transient EHL line contact problems under sinusoidal excitation or pure normal approach process are obtained. The results demonstrate that the new algorithm increases computing speed several times more than the traditional compound direct iterative method with the same numerical precision. Also the results show that the new algorithm can get the best computing speed and robustness when the ratio, half-bandwidth to total number of nodes, is about 7.5%–10.0% in moderate load cases.

针对具有复杂型面的叶片类零件检测中所面临的数字化测量问题,提出了一种复合式的测量原理与方法。分别采用接触式的电感原理和非接触式的激光三角原理测量叶片的叶根基准以及叶身型面,并基于此原理设计研制了叶片型面四坐标测量系统。研究中结合该系统的机械结构特征,对影响其测量精度的各项几何误差进行了系统的分析,并提出了基于激光干涉测量的误差提取与补偿方法。实验结果表明,应用提出的误差分析与补偿方法可有效获取叶片型面四坐标测量系统的几何误差并显著提高其测量精度。

受昆虫复眼启发,为提高光学成像质量,如获得高分辨率图像或大视场图像,研究者提出了许多多孔径光学成像系统。光场采集数学模型是联系多孔径光学成像系统结构设计与应用的纽带,但光场采集数学模型较少被关注。本文系统梳理了典型多孔径光学成像系统(仿生复眼、光场相机、相机阵列),总结了不同结构下多孔径光学成像系统的一般性光场采集数学模型。列出的数学模型既可用于计算特定多孔径光学成像系统的关键指标,如视场大小和子图像重叠比等,也可作为数学工具,便于研究者完成对成像系统的定量设计与评估。
