virtual modelling techniques

Question 1

Hand crafted models

Answer 1

• highly skilled and labour intense to create.

Question 2

CAD models

Answer 2

• can define the properties of materials and match the real life scale prototype.
• easy to edit and can be made using CAM.

Question 3

virtual testing

Answer 3

products can be destroyed with little cost and the tests can be repeated rapidly.

allows engineers to spot errors, gather precise data.

Question 4

FEA

Answer 4

Finite element analysis

FEA can measure exactly how products will react under real life forces.

weaknesses in the design can be identified and resolved

Question 5

CFD

Answer 5

Computational fluid dynamics

Simulates the flow of gases and liquids.

Tests can mimic extreme weather. Allows products to optimise the flow of gases and fluids.

Question 6

Rapid prototyping

Answer 6

is a cam method which produces physical prototypes from CAD files.

Question 7

EPOS

Answer 7

Electronic point of sale

system that allows a company to monitor sales, stock and gain insight into customer behaviour.

Sales can trigger re ordering to maintain levels of stock

can collect data on specific customers also through loyalty cards.
