Abstract: A study on the general formula of how original errors
transfer in the movement of mechanisms is carried out through analyzing
the applied force placement of contiguous bar and movement trace of
reference point about output, and the errors transferring matrix applied
for variety of mechanics is proposed, which all based on the principle
of the projection of original error in the direction of applied force. A
general method is presented combining with precision analysis examples
for plane and space mechanisms. The method has many general advantages
such as the clear conception, without differential calculation and so
on.
Key words: Mechanism Precision analysis Transfering matrix
