| 摘 要： | 采用新型润滑油在高速重载工况下研究Hamrock-Dowson膜厚公式的适用性。研究结果表明,在高速重载工况下,Hamrock-Dowson膜厚公式会带来较大误差,数值解得到的膜厚可达Hamrock-Dowson膜厚公式的2～4倍。所以随着弹流理论的发展和计算技术的飞速进步,润滑设计应不再过多的依赖于各种经验公式,可通过计算软件数值仿真和试验研究来实现。

| Abstract: | Using new lubrication oil,the suitability for the Hamrock-Dowson formula under heavy load and high speed working conditions were discussed.It was concluded that Hamrock-Dowson formula was not suitable under heavy load and high speed working conditions,and the numerical results may vary from two to four times than that of Hamrock-Dowson formula results.With the developments of EHL theory and computing technique,the lubricating design should rely on computing software and experimental technique rather than ex... |
