Abstract

By considering a disc cam mechanism with negative radius follower, an effective dimension synthesis method based on technology of the visualization-oriented mapping is presented. It shows the new configuration’s form, basic/ general dimension, accurate description and basic steps for dimension synthesis, constructs coordinate systemORr0e and areaΩ(R, r0, e) of dimension, then discretizing and gridding the dimension area. By getting the boundary /soluble region and boundary surface/ solution space of single constraint based on the way of “general search”, it also get the boundary/soluble region boundary surface/ solution space of merge constraint, successfully achieving the visual mapping of two-dimensional/three-dimensional coordinate system and scale space. According to the multi objective planning, it shows some important rules such as “bottom point/ ridge point” “non-inferior solution nterval/area/space”, “ crestal plane”, “ thalweg/ridge line”, “ gully bottom”, it also reveals the existence of optimal solution. All the consequences are instructive to the dimension synthesis of the new mechanism with comprehensive system solutions. What’s more, it gets an important conclusion. When bearing enough loading, the disc cam mechanism with negative radius follower has advantages in size compare with radius roller mechanism. This critical advantage has important theoretical value and practical significance to promote new typed mechanism into engineering application.

 

Key words： negative radius roller; dimensional coordinate system; visual mapping; bottom point/ ridge point; gully bottom point; size synthesis; comparative advantage
