| 摘 要： | 基于快速求解点接触弹流问题的直接迭代算法,通过将压力迭代矩阵由满元矩阵变为带状的稀疏矩阵,提出一个更高效的求解点接触弹流问题的新算法.该算法不仅具有更高的计算效率,而且可适用于重载工况.采用新算法求解了若干重载点接触EHL问题,结果与采用逆解法求得的结果非常接近,表明直接迭代法也适用于重载弹流问题研究.

| Abstract: | Based on fast direct iterative algorithm for point contact EHL,by changing the full elements pressure iterative matrix into a spare band matrix,a more efficiency direct iterative algorithm for point contact EHL problems was proposed.The new algorithm is more efficient,and is applicable to heavy load conditions.Some numerical examples of heavy load point contact EHL problem solved by the new method were provided,and the results were very close to the results obtained by inverse solution algorithm,which indic... |
