ABSTRACT
Environmental effects are not considered sufficiently in product design. Reliability problems caused by environmental effects are very prominent. This paper proposes a method to apply ontology approach in product design. During product reliability design and analysis, environmental effects knowledge reusing is achieved. First, the relationship of environmental effects and product reliability is analyzed. Then environmental effects ontology to describe environmental effects domain knowledge is designed. Related concepts of environmental effects are formally defined by using the ontology approach. This model can be applied to arrange environmental effects knowledge in different environments. Finally, rubber seals used in the subhumid acid rain environment are taken as an example to illustrate ontological model application on reliability design and analysis.

fig3: Environmental loads variation of subhumid acid rain climate.

Mentions: This paper selects a typical subhumid climate of acid rain as an example to illustrate the application of environmental effects ontology. High temperature, high humidity, and heavy rain are the main climatic features. According to Figure 3, this climate zone has year-round mild climate, moist air, and abundant rainfall. The average temperature is 18.3°C. The average relative humidity is 81%. There are more than 200 days all years when relative humidity is over 80%. Annual amount of radiation in the region reached 3000 MJ, where 75% of the total amount of radiation is in summer. In the region, high temperature, high humidity, acid rain, and high levels of sulfur dioxide in the atmosphere are the main factors for material aging, rustiness, and corrosion. Based on the above analysis for subhumid acid rain climate, Figure 4 shows parts of environmental load ontology of subhumid acid rain climate.
