Abstract: The design for maintainability is important in the construction machinery, and the identification of the design requirements of construction machinery maintainability is the pre-requirement. Firstly, the paper briefly discusses the QFD method, especially, the basic makeup of HoQ. Secondly, the analysis process of the design requirements of construction machinery maintainability based on QFD is discussed, mainly including six steps: analyzing the clients' maintainable requirements, evaluating the weight of each requirement, determining the design index of maintainability, constructing the design index matrix, constructing the design index and maintainable requirements matrix, and forming the design index weight matrix of maintainability. Lastly, through analyzing the design requirements of one bulldozer maintainability based QFD, the importance sequence of maintainability design indexes is obtained, as in the order: the disassembly-assembly character, the modularization, the standardization, the compactness, the accessability and the easiness to identify. It is shown that the analysis of design requirements of construction machinery maintainability based on QFD can effectively solve the problems of complexity and uncertainty in the analysis process and evaluate the design requirements of maintainability by integrating qualitative analysis with quantitative analysis, with a high practical value.
