Lean Production In Wind Turbine Gearbox Assembly Plant

The thesis mainly describes under current situation, the status of both international and domestic wind power. As a manufacturer producing wind power gear box, it is necessary for NGC to implement lean production. The thesis expatiates the assembly plant implementing lean manufacturing processes and the results it has achieved.Firstly, the thesis introduced the background and significance of topics, summarized the interrelated investigation methods of theory and conception, and then had a systemic explaining of some lean principles; secondly, based on the actuality of assembly workshop, the thesis put forward the optimized mode and improvement scheme of assemble, then, through the case analysis and simulation, designed the single piece flow of product line that seasoned with the assemble mode; lastly, after demonstration analysis, the thesis summarized the process of lean assembly and achievement that we have achieved. In the end, the production efficiency has been improved, the production line layout has been perfected, the production mode has been improved, through the implementation of Kanban, the assembly shop will upgrade to a new level.Through two years of efforts, as an idea, the lean production has been accepted by every employee, although some difficulties and problems are still existent, a climate and culture is being created which is spreading in NGC.
