Working at Kaiser Electronics, Hollmann performed the random vibration dynamic analysis and stress analysis on the fighter head up display unites for the F-14, F-18, F-111 and others to assure that the units would pass qual tests. All units passed qual tests without a problem.
While working for FMC Corporation in San Jose, CA, Hollmann conceived, proposed and won a contract from
Working for NASA, Hollmann performed a random vibration analysis on a test fixture to assure the structure would not fail from 3 sigma stress loads. The finite element analysis model results of the test unit are shown below.
