摘　　要：通过一维振动式贴壁加工实验,研究了频率、振幅、试件固定高度和固定方位对试件表面加工质量的影响规律。基于电动式振动试验系统,将6061铝合金块以不同高度嵌在橡胶衬垫里贴于垂直、平行于振动方向的自制振动容器内壁上进行加工实验。试件垂直于振动方向固定时,同一固定高度,频率(振幅)越高,试件表面粗糙度值下降越快,加工效果越好;试件平行于振动方向固定时,同一固定高度,频率越低反而加工效果越好。一定频率和振幅下,两个固定方位的试件表面粗糙度随固定高度变化规律趋于一致,但不同频率振幅下,变化规律差异大。结果表明,在相同条件下,垂直振动方向明显比平行振动方向加工效果好。垂直于振动方向固定试件主要受磨块碰撞和挤压作用,平行于振动方向主要受磨块滑擦作用。在一定范围内,频率(振幅)越大,越有利于试件的加工。The influence of frequency,amplitude,fixed height and fixed orientation of specimens on the surface machining quality of specimens was studied through one-dimensional vibration-type wall-sticking machining experiment,which further provided theoretical methods for inner surface machining of box shell parts.Based on the electrodynamic vibration test system,the 6061 aluminum alloy blocks were embedded in rubber gaskets at different heights and pasted on the inner wall of the self-made vibration container perpendicular and parallel to the vibration direction for processing experiments.When the specimen is fixed perpendicular to the vibration direction,with the same fixed height,the higher the frequency(amplitude),the faster the surface roughness value of the specimen will decline,and the better the processing effect will be.When the specimen is fixed parallel to the vibration direction,the same fixed height,the lower the frequency,the better the processing effect.Under a certain frequency and amplitude,two fixed position of the specimen surface roughness with the fixed height change law,but under different frequency amplitude,there are differences between the change rule.The results show that the vertical vibration direction is better than the parallel vibration direction under the same conditions.The fixed specimen perpendicular to the vibration direction is mainly affected by collision and extrusion of the grinding block,while the specimen parallel to the vibration direction is mainly affected by sliding and rubbing of the grinding block.In a certain range,the larger the frequency(amplitude),the more conducive to the processing of specimens.
