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

4
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.)

5
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

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

8
Dynamic Designer Features Definition

• Degree of Freedom (DOF)
• The directions an object can move in.

In 2D plane
How about 3D Space?
9
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)

10
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.

11
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)
12
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

Inserting and Specifying Joints

• Dynamic Designer Motion will create motion joints
  from assembly mates that exist between components
  in the model
• One can also manually add motion joints when a
  suitable assembly mate does not exist
