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, […]
