Education & Awards:
B.E.(M.E.), The City College, 1954;

Research Interests:
Analytical and experimental dynamics of high speed machinery
Balancing and elastic behavior of linkages
Mathematical modeling of artillery safety and arming mechanisms
Professor Lowen, together with his doctoral students, has published 33 transaction papers and 20 reports on the dynamics of mechanical systems. Early on a new method for fully force balancing planar mechanisms with a minimum number of counterweights was generalized. Later, various types of partial shaking force and moment balancing schemes were developed. A novel concept for a force balancing machine was awarded a U.S. patent. In the field of mechanism elasticity it was shown that the resonance positions of the link deflections can be predicted with the help of Floquet theory. Further progress in this field was made by way of the analysis of an industrial press feed mechanism which contains an elastic coupler and an elastic sprag clutch. Recent work produced an analytically solvable linear model of this mechanism. Finally, work for Picatinny Arsenal produced many innovations in the modeling of safety and arming devices.
