| description | In order to deeply explore the potentials of micro-texture on enhancing the performances of a multi-oil wedge sliding bearing, a three-oil-wedge radial sliding bearing is taken as the prototype to simulate its bearing pressure, friction coefficient and temperature with the CFD method. According to the prototype bearing, the elliptic opening offset parabola micro texture(EOOPT) is designed. The response surface method is used to analyze the influence of EOOPT parameters on characteristics of the three-oil-wedge radial sliding bearing, and its corresponding quadratic regression equations are established. The multi-objective optimization of EOOPT parameters is carried out to obtain the optimal EOOPT parameters. The simulation results show that the sequence of influences of EOOPT parameters on the average bearing pressure and friction coefficient of the radial sliding bearing is as follows: short half axis, semi-major axis, depth, offset, texture evenly distributed angle. The sequence of influence on average temperature is depth, semi-major axis, texture evenly distributed angle, offset, short half axis. Compared with the prototype bearing, the average bearing pressure of the optimal-parameter micro-texture bearing increases by 13.7%, while the friction coefficient and average temperature decrease by 13.8% and 8.3% respectively. |
