摘　　要：为解决矩形静压油腔的润滑特性问题,本文建立了矩形静压油腔数学模型,并采用高斯-赛德尔迭代法,应用FORTRAN语言编程求得油腔的压力分布。同时,研究了油腔中心位置偏移对承载能力的影响。研究结果表明,静压油腔的承载区域随着油腔中心位置的偏移而偏移,外油腔壁边附近的压力梯度比远离外油腔壁边的压力梯度大,且静压油腔的总承载能力也将降低,因此应提高静压油腔的制造精度,减小油腔中心位置的偏移量,以改善其压力分布,并提高承载能力。该研究为解决矩形静压油腔的润滑特性提供了理论依据。This paper aims to solve the problem of lubrication characteristics of rectangular hydrostatic oil chamber.Firstly,the mathematical model is established,and the pressure distribution of the oil chamber is obtained by using the Gauss-Seidel iteration method and FORTRAN language programming.Then,the influence of the displacement of the center of the oil chamber on the bearing capacity is discussed.It is pointed out that the bearing area of the hydrostatic oil chamber will shift with the deviation of the center position of the oil chamber.The pressure gradient near the wall of the outer oil chamber is larger than that far away from the wall of the outer oil chamber,and the total bearing capacity of the hydrostatic oil chamber will also decrease.Therefore,the manufacturing accuracy of the hydrostatic oil chamber should be improved,and the offset of the center position of the oil chamber should be reduced to improve its pressure distribution and load-carrying capacity.
