【Abstract】 The work aims to explore the needs of probing personnel for double-tracked flaw detection vehicles in flaw detection operations, improve the operational experience in flaw detection operations, and increase the satisfaction of double-tracked flaw detection vehicles. Firstly, the observation method, user interview method and scenario analysis method were used to study the behavior of flaw detection operation, and the KJ method was used to summarize and derive the basic user needs; Secondly, based on the Kano model, the user needs were classified into categories and ranked in order of importance; Thirdly, the FBS model was introduced to carry out the mapping transformation of "Function-Behavior-Structure" to get the key design elements for the optimization of double-tracked flaw detection vehicles; Finally, the innovative design scheme of double-tracked flaw detection vehicles that met the actual needs was outputted by combining with the corresponding design method. In conclusion, based on the comprehensive application of the Kano-FBS model, the core user needs of double-tracked flaw detection vehicles can be grasped and smoothly transformed into key design elements, which is conducive to the scientific and systematic completion of the design practice of double-tracked flaw detection vehicles.更多还原
