本質的安全設計を考慮した機械設備の基本設計の試行

抄録

ISO12100 provides a process of risk assessment and risk reduction (hereinafter referred to as RA/RR) to achieve the safety of machinery. This process shows a three-step method of inherently safe design measures, safeguarding and complementary protective measures, and information for use. It is specialized in how to introduce safety measures, so it is difficult to incorporate this method in the design process of machinery. The scheme design process consists of four stages: requirement specification definition, function definition, component and mechanism selection, and structural design. Classify the safety measures shown in ISO12100 by content, and appropriately allocate items to be considered in these four stages. Study at each stage is narrowed down and clarified by this task. By proceeding with this process, an appropriate design with few omissions is derived. With this proposal, a front-loading design process is implemented, and mechanical design acquires appropriate safe design measures.
