Transient Analysis of a Train

Transient moving load going down a set of elevated rail road tracks. The Analysis was done in NX/Nastran solution 129 and presents a random spectrum moving down the train track 30mph. The spectrum was converted into a time domain random signal and then applied as a moving load going from left to right over approximately […]

Scheduling – Who does What by When?

Schedule management is easy to implement when it’s done right, otherwise get ready to do multiple re-baselines. The process is similar wherever you look, including NASA schedule management guidelines, DoD Program life cycle guidelines, or Project Management Institute.  Figure 1 illustrates the six steps: define activities, sequence activities, estimate activity duration and resources, develop schedule, […]

Great Engineers Program – VBA tutorial for Excel

Introduction Programming is one of the few skills that separates great engineers from merely good ones. Programming is also the best tool I’m aware of for teaching one of the three most important traits of great engineers, curiosity (the other two are being hungry and having enough talent). The value of programming is indisputable however, the […]

Design of Aerospace Mechanisms

Download 43 Volumes Now I have recently had the opportunity to work with some clients who are developing space mechanisms. This is a very specialized field with 60 years of tribal knowledge. When working at NASA I was exposed to the Aerospace Mechanisms Symposium which is the semi-annual gathering for all things space mechanism. It […]
