Study On Quality Management Of QSY Electric Manufacture Of Locomotive

As the unceasing change of domestic situation and international environment, development of railway stimulating domestic demand, high iron foreign affairs brought the spring for railway transportation equipment industry, so the power equipment level of main railway lines should be promoted rapidly, the development of ac locomotive electric products is imminent. Electrical cabinets and harness on the locomotive plays an important role in control, how to ensure the quality plays a decisive role. The quality of control appliance is crucial for QSY locomotive, but due to the deficiencies and factors of corporation, a lot of quality problems happened which bring great economic losses and bad influence.This paper researches QSY Company's actual management with case analysis. First, this paper introduces the general situation of QSY Company and current product development mode, analyses problems of project quality management with theory and practice, identifies the key factors. Second, combined with the theory and the key factors of project quality management, the paper analyses reasons which influence the project quality management of control appliance development: the quality management idea lag, project quality management process and the method is not science, design process is not perfect, process scheme design process is not perfect, process quality control method is not in place, the lack of scientific quality cost control and rewards and punishment system, etc. Finally, according to QSY Company's actual situation, this paper provides several improvement strategy to project quality management of QSY locomotive electric appliance product development: QSY Company sets up the new quality management concept, perfects the system of the project quality management processes, improves the design process, improves the process scheme design process, perfects the process control methods, establishes the guarantee system and controls the quality costs reasonably, pays attention to the human resource construction, etc.This paper solves the problems in this case through study. It provides a more scientific and systematic project quality management mode, process and method for subsequent control appliance development of QSY locomotive. It is advantageous for the company to carry out the project quality management and improve the quality of new products.
