SOFTWARE FOR COMPUTING THE FORCE TRANSFER RATIO
Ion GROZAV, Tünde NICOLI
Abstract: In the paper it is presented the software that helps the designer to compute the force transfer ratio of a clamping mechanism, especially in the case of the workholding. For the calculus of the force transfer ratio was used an original method named Force Separation Method (FSM). This method is simple, precise and gives the possibility to observe easy the reserve of the auto-blocking and auto-braking of the clamping mechanism. There are presented the cases of planar clamping mechanisms with n = 3 or n = 4 contact points. In the case n = 3 are included wedge, lever and circular eccentric like amplifying elements. The paper includes also a planar model for computing the screw force transfer ratio. In the case n = 4 was included the plunger.
Key words: software, force transfer ratio, clamping mechanism, workholding, design.
