Research On Safety Allocation Model Of Machinery ＆Electrical Products

With the development of science and technology, machinery&electrical products have become one of the necessity for life. Also, because of the poor product safety which led to casualties and property losses are a common occurrence. Therefore, How to allocate the safety of the product to an acceptable range reasonably, in the early stage of product design has become the most important to the safety of machinery&electrical product.In this paper, based on previous studies of safety quantitative model and criticality of machinery&electrical products and the concept of reliability allocation, proposed the concept of distribution of product safety and the safety allocation model for machinery&electrical products were established. Firstly, the types of mishaps were qualitatively assessed with RAC and based on the consequences of different types of accidents of different parameters selected for distribution to its safety. Secondly, applying the FTA, the Effort Minimization Algorithm and the size of safety criticality to the components to allocate the safety for the type of product mishaps, minimal cut sets and the components in hazardous state. Again, in the restriction of the economic and technological level adjusted the allocation of safety to make it more practical significant.Finally, some type of elevators as an example of the allocation model of machinery&electrical products safety has been applied, then the results of the study were verified.
