VALDYN
VALDYN is a dynamics simulation package which has been specifically developed for valvetrain and drive system analysis. The package incorporates a graphical user interface which allows complex models to be constructed rapidly and accurately. With its detailed "building block" models of valvetrain components, VALDYN can be significantly more efficient than many of the general purpose dynamics tools as model refinement is focussed on those aspects critical to valvetrain dynamics.;With shorter model construction and run times together with the improved accuracy of the approach, it is possible to complete many more analyses in a given project time scale.
