【摘要】 针对现有风险评估方法不适用于确定机械安全风险预警监测要素的问题，提出基于机械安全风险预警系数的监测要素确定方法。首先通过计算建设成本系数(CFF)、运维成本系数(MCF)和效率影响系数(EIF),获得机械安全风险预警系数，用以对比风险预警系统和安全防护装置的安全成本，并作为选择风险减小措施的依据；然后定义监测要素确定流程，包括机器限制确定、危险识别、风险估计、风险评价、机械安全风险预警系数确定等；通过某工业机器人监测要素确定案例，验证机械安全风险预警监测要素确定方法的有效性。研究表明：该确定方法可合理选择监测要素，确定系统的危险性，估计风险大小，同时考虑安全风险减小措施的经济性。更多还原

【Abstract】 Aiming at the problem that the existing risk assessment methods are not applicable to the determination of monitoring elements of mechanical safety risk early warning, this study proposes a method to determine monitoring elements based on mechanical safety risk early warning coefficient. By calculating the construction cost factor(CCF), operation and maintenance cost factor(MCF)and efficiency influence factor(EIF), the early warning coefficient of mechanical safety risk was obtained, and the comparison of risk early warning system and safety protection device in safety cost was realized, which serves as the basis for selecting risk reduction measures. At the same time, the process of defining monitoring elements was proposed, including the determination of machine limits, hazard identification, risk estimation, risk evaluation, and determination of mechanical safety risk early warning coefficient. Through a case of determining the monitoring elements of an industrial robot, the validity of the determination method of mechanical safety risk early warning monitoring element was verified. The study shows that the determination method can reasonably select monitoring elements, determine the system risk, estimate the risk size, and consider the economy of measures with small safety risks.更多还原
