一、引言对机器进行风险评价是实现机械安全的重要方法,贯穿于机器的设计、制造、使用、维修、拆卸和回收等寿命周期的各个阶段。风险评价具有较强的理论性,实施过程也比较复杂。本文介绍了一种实用的机械安全风险评价程序,并将该风险评价程序应用于一 I. INTRODUCTION Risk assessment of machines is an important way to achieve mechanical safety throughout the life cycle of the machine design, manufacture, use, maintenance, disassembly and recycling. Risk assessment has a strong theoretical, the implementation process is more complicated. This paper introduces a practical procedure of mechanical safety risk assessment, and applies the risk assessment procedure to a
