振动时效是一种先进的时效方法,它与热时效比较,在保证质量的前提下,具有节约能源、节省投资和缩短生产周期等优点。为适应电力机车生产发展的需要,提高社会效益和技术经济效益,我厂加快了振动时效新工艺的研制。从1988年8月至1989年10月,工厂与驻厂验收室一起会同湖南省机械厅、湖南大学和戚墅堰机车车辆工艺研究所对SS_3型电力机车转向架构架进行了全面系统的振动时效工艺试验研究和残余应力测定,完成了构架振动时效工艺参数优选,振动前与振动后焊接残余应力和热时效前与热时效后焊接残余应力测试工作。测试报告的数据表明,构架经振动时效处理,焊接残余拉应力平均值降低57％(四个振动点)和85.97％(六个振动点)。而经热时效处理的构架,焊接残余拉应力平均 Vibration aging is an advanced aging method, compared with thermal aging, under the premise of ensuring quality, with the advantages of saving energy, saving investment and shortening the production cycle. In order to meet the needs of the development of electric locomotive production and improve social benefits and technical and economic benefits, our factory has accelerated the development of new technology of vibration aging. From August 1988 to October 1989, the factory and the factory acceptance room together with the Hunan Provincial Department of Machinery, Hunan University and Qishuyan Rolling Stock Technology Institute of SS_3 electric locomotive bogie frame conducted a comprehensive system of vibration aging test Research and determination of residual stress, completed the vibration parameters of the framework of the preferred process parameters before and after vibration welding residual stress and thermal aging and thermal aging after welding residual stress testing. The test report data shows that the average residual tensile stress of the structure is reduced by 57% (four vibration points) and 85.97% (six vibration points) after vibration aging treatment. The thermal aging of the framework, the average welding residual tensile stress
