文摘
- •
Mobility of over-constrained structures is established from the viewpoint of symmetry.
- •
Constraint equations and elementary compatibility matrix for a general link are given.
- •
Null-space of each block matrix indicates all symmetries of internal mechanisms.
- •
The method can evaluate the mobility of known mechanisms, and also discover novel linkages.
