According to the process with no drive, data with no carrier and other issues in the rapid design process of complex mechanical products, a new multiplatform rapid design method of products was put forward based on the consistency model of product information and the whole design process.This paper studied the top-down parametric modeling theory based on the skeleton model deeply, and elaborated on the seamless integration technology of multiplatform software, including specification calculation, optimization analysis, parametric model driving, storage of design data and planning method of data model.The rapid product design software architecture was constructed on the basis of the above research.At last, a rapid optimization and design platform of tower crane was developed on the basis of this method, and one tower design example was completed whose design circle was shortened greatly and lightweight effect was obvious.The rationality and practicability of the rapid design method proposed was also demonstrated.
