Abstract: Based on the concept of requirement analysis and its present research status, the requirement analysis modeling method is brought forward according to the characteristic of mechanical products. The formalized product requirement description results are educed through functional semantic description and standardization to requirement analysis result and the semantic analysis of the requirement description on the basis of product requirement database.
