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.)

The Functionality

Mechanism Animation


Moving Interference Detection



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.
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

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



Determine power consumption


See how friction will increase power requirements and actuators size
Force Transmission


actuator power consumption is immediately available in an XY plot
Friction


What kind of motor to use?
Solve problem like underestimating peak motor torque.
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
