项目摘要

We sent out a questionnaire to marine engineers in the shipping lines about the bolt tightening management. As a result, it was appeared that there were plural views to lubricant, for example the kind and the way of sweating, for bolts at the same part of the main engine, and to the ways of bolt tightening. Then, to answer the difference between the uncertainty and the idea in the content of the description of the questionnaire, we verified them by the experiment demonstrated about influence of the lubricant and the posture in bolt tightening, and the effectiveness of match mark.

我们向航运公司的轮机工程师发出了一份关于螺栓紧固管理的调查问卷。结果，对于润滑油的种类和方式，对于主机同一部件的螺栓，对于螺栓的拧紧方式，似乎存在着多种观点。然后，为了回答问卷描述内容上的不确定性与意想性之间的差异，我们通过润滑剂和螺栓拧紧姿势的影响以及配对标记的有效性的实验来验证。
