Though the physical burdens by welding works and manual material handling works in the shipbuilding have been studied before, the grinding work will be one of the most severe work for the human body. In the grinding work, undesired sound, hand-arm vibration and reaction force from the tool are big, and the adequate countermeasures for the body work seem to be necessary, because the aging of the workers and embrittlement of the youth will become remarkable in near future. Therefore, in this paper, the human body analysis at grinding work has been carried out,using general-purpose human simulation software "Jack"; static strength prediction of human body, lumbar force analysis, and energy consumption analysis, same as previous reports. This time, "Kansei Engineering" technique has been introduced for the evaluation of the results by biomechanical analysis. SD (Semantic Differential) evaluation has been carried out concerning the body feeling of the grinding workers, and then multiple factor analysis, one of multivariate analysis, has been executed, according to the process of "Kansei Engineering". The results have been compared with the analytical results by the digital human model, and it was concluded that both were well coincided especially for the lower human body.
