The Tools, They are a Changing’

(regarding the title, just think Bob Dylan’s “The Times They are a Changin”)

Just as Computer Aided Design, CAD, has revolutionized the design process, it is growing in capability and impacting many other arenas of engineering. The first major extensions to CAD were integration of Finite Element Analysis, the ability to analyze loads on the parts being created.  And certainly, if the design software can model the complex aspects of loading, then animation of part motion can’t be a far reach.  And that’s the case today.

Integrate Test with Design and Analysis

The common definition of mechatronics does not include testing. Perhaps it should.

In the traditional design process of parts and assemblies, engineers produce models, analyze their behaviors under operating conditions, and pass physical prototypes “over the wall” for test engineers to evaluate in a pass-fail mode. Any problems that come to light are “thrown back” for design changes that, though necessary, come at the cost of additional prototypes and development time.

If that wall could be broken down, with analysis and testing working together in a closed-loop cycle, both groups would reap benefits from the use of test-based input values to drive analysis models, the use of analysis results to recommend sensor locations and test scenarios, and faster and better product development cycles.
