The development of kinematic mechanisms on the design board is often a
n extremely complex and time-consuming task. The Spacebar program allo
ws the direct design and analysis of mechanisms on the terminal screen
. All variables, including linkage geometry, stiffness, and applied lo
ading conditions, can be input and/or changed from the terminal. The d
ata can be described and displayed in 3D. All mechanism configurations
can be cycled through their range of travel, and viewed in their vari
ous geometric positions, again in 3D. Output data includes the geometr
ic positioning in orthogonal coordinates of each node point in the mec
hanism, the velocity and acceleration of the mechanism node points thr
oughout its range of travel, and the internal loads and displacements
of the individual node points and linkages. All analysis calculations
are performed at the VDU, and they take, at most, a few seconds to com
plete. Output data can be viewed at the scope, and also printed, at th
e discretion of the user.
