Chain dynamics

VALDYN can be used to model most types of chain including roller and inverted tooth (silent) chains. Generation of chain models is fast and simple with minimal data input and automated wrapping of the chain around the sprockets. Sprocket tooth, link and guide shapes can be built from lines, arcs and involutes or defined by B-splines which can be fitted to measured data.

The behaviour of the chain can be viewed as an animation both in the time domain and as mode shapes in the frequency domain. Comprehensive plotted output of force, friction and power loss is available. The time variation of forces on individual components or at given points in the chain run, and spatial variation of forces around the chain run can also be plotted.
