Creo Mechanism Dynamics Intensive
Course Duration: 16 hours
Overview: This Creo Mechanism Dynamics course is intended as a two-day intensive on using Creo Mechanism. Emphasis can be placed on your specific Creo Pro/E Mechanism interests. In this Creo Mechanism course, you will learn to use “connections” and “drivers” to build elegant assembly models using existing Creo parts, and you will learn how to convert an existing Creo assembly into a Pro/Mechanism assembly. You will learn how to use this module to perform optimization studies, find motion envelope information, do dynamic global interference checks, utilize collision detection and create assembly demonstration movies. These movies can be incorporated into PowerPoint presentations for use in design reviews and sales presentations to effectively communicate in action how your assembly is intended to function and effectively impress your management, marketing, or sales personnel. The end result will be reduced design time and higher design confidence by providing concurrent simulation of potential interference over a range of motion resulting in failures before prototypes are created.
Projects: Each project will take about an hour and they are detailed below on this page. Design Engine is flexible and often we customize our training upon participant’s manufacture interests or job requirements. Always ask to speak to an instructor before class.
Prerequisites: Minimum experience with Creo Assemblies.
- Basics of high end assembly constraints.
- Mechanical degrees of freedom concepts, and how it relates to an assembly.
- Use “connections” instead of “constraints”.
- Types of connections: Sliders, Pins, Gears, Slots, Cylinders, etc.
- Move your mechanism manually by “grabbing” it with your virtual hand.
- Create motors or drivers to automatically move your more complicated assembly apparatus using equations, and tables.
- Utilize collision detection to manipulate assemblies.
- Understand the types and effects of dynamic motion (position, velocity, and acceleration) when choosing the right driver equation or table.
- Dynamic global interference checks.
- Output of digital movies – link them into Powerpoint for manager presentations.
- Discuss the use of Creo Mechanism powerful tool with other simulation and optimization tools such as Mechanica.
Project 1: Build a simple Four Bar Linkage. Watch how the links interact with each other just by driving one of them. Experiment with using links of different sizes together.
Project 2: Create the Slider-Grinder apparatus.
Project 3: Create the Clamp Assembly and observe how rotating the handle beyond a certain equilibrium point prevents the output link from back-driving the system, effectively locking the clamp in position.
Project 4: Assemble piston and crank parts and use servo motors to power the configuration driving the piston up and down.
Project 5: Create a Backhoe Linkage using simple parts and constraints. Convert linkage into a Mechanism by converting standard constraints into connections. Grab linkage and move it to its mechanical limits. Insert servo motors to power the piston links to drive the linkage. Create “snapshots” of mechanism at initial and final positions.
Project 6: Create a slider mechanism to convert rotational to linear actuation. Add Springs & Dampeners to the model. Run Analysis between each new addition.
Project 7: Explore Collision Detection tools with a GoPro camera housing and Latch Mechanism. Use Mechanism functions to limit the motion so to simulate reality. Discuss or actually modify the Latch Geometry to optimize the product.
Project 8: Utilize the given piston & rod assembly by adding a servo to spin up the assembly. Utilize Position tables, Velocity then Acceleration equations to generate MOV files. Make a movie and Power Point Presentation of the results. Demonstrates a wide variety of concepts that have been discussed.
- Discuss the purpose and functionality of the buttons while in Mechanism mode.
- Discuss scenarios when this powerful Creo module would be useful.
- Discuss connections vs. constraints and degrees of freedom.
- Discuss Creo 3.0 vs Wildfire 4.0 iconography.
Project 9: Convert an assembly of your choice into a Creo Mechanism Dynamics assembly and output the results in the form of a movie.
Project 10: Utilize the Gears supplied and learn to create Gear Constraints for Spur, Bevel, Worm, Rack&Pinion Gears.
Project 11 (Advanced): Find the weakest link in the Backhoe linkage you built in Exercise 5, by finding the greatest load in each link during its motion envelope.
Project 12: Utilize the Cam Shaft & Cams supplied & learn to create Cam & Follower Constraints using Creo 2.0 then use all you have learned to spin up the shaft and export various movies. Learn to evaluate the graphs.
Project 13: Utilize Theo Janson’s Kite walker supplied models & rebuild them as pin & cylinder Constraints.
Project 14: Utilize the supplied Scotch Yoke Assembly and re constrain using Slider the parts using Creo Mechanism constraints.
Project 15: Utilize the supplied Lamp models using springs and dampeners to analyses and optimize the geometries.
Project 16: Utilize the supplied Clamp models using springs and dampeners to analyses and optimize the geometries.
- Discuss the differences between using a Pro/Skeleton and a Pro/Mechanism to simulate motion and the effects of design changes with each method.
- Discuss Pro Simulation “measures” and load graphs in the context of Pro/Mechanism.
- Discuss connection “order” and component packaging loops that close with last component leaving a fully constrained assembly.
- Discuss the difference between pin & cylinder constraints.
- Discuss external references and assembly “etiquette” while creating mechanized drivers.
- Discuss the pros and cons of each type of driver table (Position, Velocity, Acceleration) and choosing the best one to simulate your type motion.
