43. Computer Model of Valve Train
and Spring Development
• One of the primary reasons to upgrade our cam design
software was to allow dynamic modeling
• If we can run a virtual Spintron test of the system before
making parts, it shortens the development cycle and
helps us choose wiser time investments
• Such software does little good without spending the time
testing to ensure we have excellent model correlation
