method three of the most widely used approaches, failure mode and effect a nalysis ( fmea ), fault tree analysis ( fta ) and system hazards analysis ( sha ) were used 方法綜合采用故障模式影響分析方法、故障樹分析方法和危險分析方法等安全性分析方法。
system danger analysis of machine-product is to do system hazard analysis for the small system and whole system to find out those that do not agree with possibly system safety objective and demand from whole system 機械產(chǎn)品系統(tǒng)危險分析是對機械產(chǎn)品各主要子系統(tǒng)及整個系統(tǒng)進行系統(tǒng)危險分析,從整個系統(tǒng)角度找出與我們期望的系統(tǒng)目標和要求可能不符的地方。
its main content include system safety objective and demand of machine-product and system hazard analysis of machine-product and system risk assessment of machine-product and system safety measure of machine-product and system safety program design of machine-product 其內(nèi)容主要包括:機械產(chǎn)品系統(tǒng)安全目標和要求、機械產(chǎn)品系統(tǒng)危險分析、機械產(chǎn)品系統(tǒng)風險評價、機械產(chǎn)品系統(tǒng)安全措施、機械產(chǎn)品系統(tǒng)安全程序設計等五個部分。
on the base of system hazard analysis of machine-product and system safety objective and demand of machine-product, we can do system risk assessment of machine-product to determine unsafe part or system, so that we can make good safety measure 在機械產(chǎn)品系統(tǒng)危險分析的基礎上,針對機械產(chǎn)品設計的系統(tǒng)安全目標和安全要求對機械產(chǎn)品進行系統(tǒng)風險評價,來判定哪個部分或哪個子系統(tǒng)是不安全的,從而為我們制定有效的安全措施找到依據(jù)。
