Creo 7.0 Mechanism Design: A Short Course Tutorial
About this ebook
In Detail
If you ever need to model a device where parts and subassemblies can move relative to each other, you will want to use the world-renowned mechanism functions in Creo. Creo’s Mechanism Design functions allow you to examine the kinematic properties of your device: range of motion and motion envelopes, potential interference between moving bodies, and kinematic relationships (position, velocity, acceleration) between bodies for prescribed motions. With these functions, you will better predict the actual performance of the device and create design improvements without the expense of costly prototypes, saving you time, money and worry.

With this tutorial, you will assemble and analyze a simple slider-crank mechanism. Each chapter has a clear focus that follows the workflow sequence, and parts are provided for the exercise that include creating connections, servos, and analyses. This is followed by graph plotting, collision detection, and motion envelope creation. You can choose to quickly cover all the essential operations of mechanism design in about two hours by following the steps covered at the beginning of chapters 2-5, or you can complete the full chapters or come back to them as needed. Plenty of figures, screenshots and animations help facilitate understanding of parts and concepts.
Once you have completed chapters 2-5 and the slider-crank mechanism, chapter 6 familiarizes you with special connections in Mechanism Design: gears (spur gears, worm gears, rack and pinion), cams, and belt drives. The final chapter presents a number of increasingly complex models (for which parts are provided) that you can assemble and use to explore the functions and capability of Mechanism Design in more depth. These examples, including an In-line Reciprocator, Variable Pitch Propeller and Stewart Platform, explore all the major topics covered in the book.
