| 摘 要： | 激光表面微造型技术是改善摩擦副表面摩擦学性能的有效途径之一。基于声光调Q技术的二极管泵浦固体光源（DPSS）Nd:YAG激光器，采用“单脉冲同点间隔多次”激光微加工工艺，对CA6DF2-26型柴油机气缸套内孔表面进行激光珩磨加工。加工出的缸套网纹参数具有较好的一致性，达到了主机厂的技术要求。进行了激光珩磨缸套的台架综合性能试验研究，结果表明，采用激光珩磨缸套的发动机，其功率、扭矩、燃油消耗指标保持稳定，与采用传统平台珩磨网纹缸套的发动机相比，柴油机的机油油耗降低53％，漏气量降低近50％。

| Abstract: | Laser surface texturing(LST) is an effective approach for improving the tribological properties of friction pair.Experimental results indicate that it is practicable to apply single pulse interval laser honing technology to cylinder bore surface of CA6DF2-26 diesel engine,based on Q switched diode-pumped solid-state(DPSS) Nd:YAG laser.The texturing micro-structures accord with the technological requirements of the engine factory.Experiment on performances of engine bench scale test has been carried out.It is found that the characteristics of power,torque and fuel consumption keep stable,the oil consumption is reduced by 53% and the emission of combustion engines is reduced by 50%,comparing with traditional plateau honing technology. |
