Abstract:
The criterion of contact loss between pairing elements is an
important problem in the field of dynamics of mechanism with clearances.
It is the theoretical basis for the design of avoiding impacts, reducing
noises and prolonging the life of mechanisms. According to theoretical
analyses, this paper points out the deficiencies of the oriterien which
is now used and puts forward a new, more effective criterion. The
correctness of this new criterion is verified by calculating the dynamic
response of a planar four-bar mechanism with clearances.
