摘　　要：在复合直接迭代法基础上,通过将整个二维求解区域化为若干部分、降低方程组维数、分条求解,提出一种新的求解点接触弹流润滑问题的直接迭代算法。该算法保留了复合直接迭代法所有优点,但计算效率提高了10倍以上,同时具有更宽的载荷适用范围。Based on the composite direct iterative method,by dividing all the two dimension solution area into a certain number of parts to reduce the dimension of the equations,a new fast direct iterative scheme for the calculating of point contact EHL was proposed. The new method retains all the advantages of the composite direct iterative method,but has more than ten times calculating efficiency and more wide-ranging load than that of composite direct iterative method.
