1、附录Machinery product scheme modern times design procedures and developing trendAbstract: Be based on the type designing that the scholar carries out the main thought characteristic time machinery product design at present at home and abroad , summarizing product scheme design procedures for systemati

The characteristic pointing out four kinds method and their organic connection thinning out mutually, suggest that the product scheme designs the effort direction that the computer realizes.Key

But, product design, e

At present, computer-aid product design plotting, designs that the comparison calculating , processing fabrication , th
5、e production planning to already studies, wins initial success together broad and thorough, but product exploitation initial stage scheme computer-aid design can satisfy the need designing that but far from. For this purpose, the author goes ahead in the basis having read large amount of document ,
6、summarizes that the scheme having summed up the method adopting time the design designing that the scholar carries out a scheme at home and abroad, and having discussed the organic connection and machinery product between various method designs the developing trend that the computer realizes.The sch

The plain that our country also has to design that the scholar has adopt similar method to describe a product is

The logic tree builds request function correlation matrix again according to request function , to describe the complicated relation between satisfying what request needs a function, relation indicating that the request and the function thin out one to one correspondences out.Kotaetal looks on the matrix as the basis that mach
