Abstract:

Four vector equations are established for the non-planar nine-link Barranov truss. A vector method with complex numbers according to four loops and its equations are changed onto an equitation group with complex exponential form. Above all, the 4 equations are reduced to a 46 degree univariate polynomial equation by Sylvester resultant elimination and the other 3 variables are solved by Euclid’s Algorithm. A numerical example is given, it verifies that assembly configurations number of the Barranov truss is 46.

Key words: non-planar nine-link Barranov truss, resultant elimination, polynomial remainder method, displacement analysis
