+Pro/ENGINEER Mechanism Intensive

Course Duration: 16 Hours

Tuition: $1500.00 US

Overview: This course is intended as a 2 day intensive on using Pro/MECHANISM in detail with an emphasis on your specific interests if a longer customized course is necessary You will learn to use “connections” and “drivers” to build elegant assembly models using existing ProE parts, and you will learn how to convert an existing ProE 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, 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. 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.

Class example: Clamp Assembly.

Prerequisites: 1,000 hours minimum experience with Pro/ENGINEER

Topics:

• Basics of high end assembly constraints
• Mechanical degrees of freedom concepts, and how it relates to an assembly.
• Using "connections" instead of "constraints"
• Types of connections: Sliders, pins, gears, slots, cylinders, etc.
• Moving your mechanism manually by "grabbing" it with your virtual hand.
• Creating "motors" or drivers to automatically move your more complicated assembly apparatus using equations, and tables.
• Understanding the types and effects of dynamic motion (position, velocity, acceleration) when choosing the right driver equation or table.
• Dynamic global interference checks
• Output of digital movies - link them into Powerpoint etc. for manager presentations.
• The use of this powerful tool with other simulation and optimization tools.

Thudbuster Assembly

Slider and Grinder Assembly

Day 1
Project 1:
Build a simple four bar assembly.

Project 2:
Create the Slider Grinder apparatus

Project 3:
Create the clamp assembly

Project 4:
Bike Thudbuster project

Project 5:
Crate a Backhoe linkage using simple parts and standard constraints
Convert linkage into a mechanism by converting standard constraints into connections.
Grab linkage and move it to mechanical limits
Create “snapshots” of mechanism at initial and final positions.

Discussion:
Discuss the purpose and functionality of the buttons while in Mechanism mode.
Discuss scenarios when this powerful Pro/E module would be useful.
Discuss connections vs. constraints and degrees of freedom
Discuss Wildfire 2.0 vs Wildfire 4.0 iconography.

Day 2
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 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.

Project 6: Convert an assembly of your choice into an assembly and Output the results in the form of a movie.

Project 7: Convert a garage door into a fully animated assembly and find the best equation or table to use as a driver to best simulate the motion of the door in the track. Determine the optimum location of cable tension monitor. Make a movie and Power Point Presentation of the results. Demonstrates a wide variety of concepts that have been discussed.

Project 8: (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.
