Abstract: To evaluate the resource saving effect of product platform design, a new method of adaptability-oriented parametric product platform design was proposed based on similarity analysis and cluster analysis. With this method, the optimization meta-model of product structure for diversified design requirements was built through variant analysis technique. Firstly，the common variables candidates which could be shared were determined through analyzing the sensitivity of the design variables.Then the concrete number of the common design variables was redefined and categorized by similarity computation and cohesion analysis. Several sharing parameter platforms for product family were established. Taking adaptability threshold value as constraint, product evaluation was conducted through adaptability computation. This method of product platform design was validated by a case study of spin cutting machine design.
