Abstract: A parametric modeling method for hyperbolic weigh bin is proposed to solve the problems of repetitive and complicated modeling process and modification process. Each part of the hyperbolic weigh bin is modeled and model parameters are set by using Creo Parametric software and skeleton modeling technique. The assembly model of hyperbolic weigh bin is obtained by assembling the part models in the default way. The parametric modeling of hyperbolic weigh bin is realized by using the relational expression to correlate the parameters of each part and setting the parameters program in the assembly model. The results show that this method achieves the effect of driving the whole model with minimum parameters and greatly improving the design efficiency of hyperbolic weigh bin, which provides a strong guarantee for the standardization and serialization design of hyperbolic weigh bin.
