Automation, Robotics & Mechatronics Laboratory Demonstration of Dynamic Designer for Solid Edge for Newfane High School Date: Oct. 26, Nov 2, 2002 by Rajan Bhatt, Graduate Student Chin Pei Tang, Graduate Student Dr. Venkat Krovi, Supervisor
Demo Overview • Why are we here? • Brief description of Functional Virtual Prototyping • What is Dynamic Designer? • Functionality • Frequently asked questions • Features and Definitions, Applications • Tutorial and Trainings, Resources available • Motion Tutor Step-by-step tutorial to get you started • Discussion of the examples: • Simple Pendulum • Fourbar Mechanism • Actuator Clamp • Governor • Scissor Lift
Functional Virtual Prototyping • Functional Virtual Prototyping refers to virtual testing of functioning of your mechanical designs without having to build and test physical prototypes • How? • First: Create motion models containing constraints, contacts, forces, and actuators • Second: Simulate mechanism motion • Third: Review animations, plot engineering data, and check for interferences
What does Dynamic Designer do? • Offers a powerful simulation engine • Permits functional simulation of your CAD models (Solid Works or Solid Edge) and outputs the same physical information (part interference, motor size, cam performance, gear and linkage layout, etc.) Pictures courtesy: http://www.dynamicdesignermotion.com/se/support/faq/index.htm
The Functionality • Mechanism Animation • Animate mechanisms based on the assembly constraints, any additional constraints, and actuators using a VCR-type interface and save it to an AVI or a VRML file. • Moving Interference Detection • Check for interferences between parts as the mechanism moves through the real operating range. • The motion of many mechanisms results from contacting parts. • Engineering Data • visualize animations synchronized with XY plots of engineering data. • displacement, velocity, acceleration and reaction load/moment… Pictures courtesy: http://www.dynamicdesignermotion.com/se/support/faq/index.htm
Frequently Asked Questions http://www.dynamicdesignermotion.com/se/support/faq/index.htm The following links should provide answers to most basic Dynamic Designer questions that you may have. InstallationResolve basic installation issues such as what operating systems and versions of Solid Edge Dynamic Designer can be installed on. Evaluation Find out how to obtain evaluation copies of Dynamic Designer and other evaluation options. LicensingDiscover the different licensing options you have to choose from and how they work. Features and DefinitionsAnswer your questions regarding Dynamic Designer features as well as an explanation of terminology used in the software. FunctionalityInvestigate how to take advantage of all the functionality that Dynamic Designer has to offer. ResultsLearn how to study the results of your simulation through plots and FEA analysis. ApplicationsView a list of industries and applications where Dynamic Designer can be used. Tutorials and TrainingFind out what type of training is available to users as well as information on tutorial models.
Dynamic Designer Features & Definition “ So what is the minimum amount of terminology I will need ?” • Dynamics: Kinematics & Kinetics • Kinematics: Study of motion without regard to forces, gravity of motion. • Kinetics: Study of forces on systems in motion
Dynamic Designer Features & Definition • Degree of Freedom (DOF) • The directions an object can move in. In 2D plane How about 3D Space?
Dynamic Designer Features & Definition • DOF (Contd.) • 2D Motion (3 DOF) • 2 translation & 1 rotation (2 lengths & 1 angle) • 3D Motion (6 DOF) • 3 translation & 3 rotation (3 lengths & 3 angles)
Dynamic Designer Features & Definition • How joints affect DOF • Joints (or constraints) restrict specific degrees of freedom between parts. • In doing this, they limit the directions the parts are free to move with respect to each other.
Dynamic Designer Features & Definition Revolute Joint 1 DOF (2 DOF restricted) Slider Joint 1 DOF (2 DOF restricted) Pin in slot 2 DOF (1 DOF restricted)
Applications “ So how will this benefit my FIRST Robotics project?” • Size motors and actuators • What kind of motor to use? • Solve problem like underestimating peak motor torque. • Determine power consumption • actuator power consumption is immediately available in an XY plot • Friction • See how friction will increase power requirements and actuators size • Force Transmission • Understand how forces are transmitted through a mechanical system • Spring and Damper Stiffness • the effect of spring/damper systems on system motion, quickly experiment with spring/damper rates

Tutorials & Trainings “ So how do I get started?” • A detailed tutorial comes with the software http://www.dynamicdesignermotion.com/download/service_packs/DDMSE01R1-01.pdf • Downloadable online training example Models: • Fourbar, Governor, Actuator Clamp, Electro-Mechanical Switch. http://www.dynamicdesignermotion.com/se/support.htm
Resources • These are all available online (links provided in your booklet): • Dynamic Designer Motion Professional Manual (For Solid Edge) http://www.dynamicdesignermotion.com/download/service_packs/DDMSE01R1-01.pdf • The Quick Start File (also called Motion Tutor) – We will go over this today…
Let’s take a break… Next… “Motion Tutor” Available in the booklet … Step-by-step walk through the tutorials
Fourbar Mechanism Example Slide based on original presentation developed by Jeffrey A. Webb, OSU Gateway Coalition Member
