Research on Existences and Concept System of Rotation Symmetry in Mechanical Systems

摘要

Rotation symmetry is a basic type of mechanical static structure symmetry, and plays an important role in mechanical systems. Based on collecting and analyzing rotation symmetric instances, the concept system of rotation symmetry classified by the directivity of symmetry components, the rotary type of symmetry components, the alternations of symmetry components, the distributing integrality of symmetry components and the type of symmetry benchmark was established, and was explained and verified by accurate instances. The concept system of rotation symmetry can offer the academic basis to the further research on the existent type, the application methods and the application laws of rotation symmetry in mechanical systems.
