It described the concept of bionics design,methods and models,analyzed the process of form bionics,namely,biological prototype-biological model-mathematical model-test model-product model.Pointed out that form bionics is not a simple mechanical imitation,but the re-creation in repeated practice,finally comprises form that is quite similar to the shape rather than the full with biological prototype.On this basis,to high-speed train (front),car,motorcycle,IT products,and commodities as some examples show that their applications in bionics design.Product form through bionics design,with its natural biological form,directly impacts on people's vision,to give a more intuitive,close,beautiful,lovely feeling.Great importance to environmental protection,particularly in today,bionics design of product shape is especially important.
