MAPLESOFT, represented in Australia by Ceanet Pty Ltd , has launched DynaFlexPro, a Maple-based design tool that uses revolutionary symbolic computation methods to rapidly derive the system equations of complex mechanical multibody systems.

Unlike other multibody design tools that use purely numeric solvers, DynaFlexPro generates solutions that are exact, compact and efficient for real-time implementation, at a fraction of the cost.

Designed by MotionPro and launched under the MapleConnect Premier program, DynaFlexPro is the result of many years of research and development, with applications in complex mechanisms, vehicle suspensions, stability control, trains, articulated vehicles, vibration analysis, robotics, biomedical prosthesis design and piano mechanisms.

DynaFlexPro overcomes the shortcomings of existing mechanical analysis tools, which use inefficient numerical algorithms to evaluate rotations, displacements, forces and torques in a mechanism.

Other tools introduce errors in analysis and the analysis is very slow — too slow for implementation in a real-time simulator, for example.

In addition, models are difficult to parameterise, for example, if a link length is changed, the whole model must be recomputed for the new value.

DynaFlexPro solves these problems by using Maple for solving complex mathematical problems and creating rich, executable technical applications to symbolically generate the equations of motion for the mechanism.

This results in an exact form representation of the mechanical system that is completely parameterised, error-free and very quick to evaluate when numeric data is introduced, making the model ideal for real-time use.

Furthermore, the Maple code generation capability can be used to export the model to other tools such as MATLAB/Simulink, MATRIXx/SystemBuild and LabVIEW.

A graphical user interface, DynaFlexPro ModelBuilder, facilitates the rapid creation of system models using block diagrams and drop-down menus.

DynaFlexPro combines graph theory with engineering mechanics in algorithms that automatically generate the system equations from the system model.

Powerful Maple computer algebra technologies are used to create small and efficient sets of system equations in symbolic form, which allows for viewing, physical insight and sharing. This symbolic approach facilitates the design, optimisation, simulation and control of complex engineering systems and is well suited for teaching mechanical system design.
