Research

Professor Klamecki’s current research interests are in three general areas: 1) Machine and mechanical process monitoring, in particular development of signal analysis techniques. 2) Magnetic treatment of manufactured parts and the control of tribological processes using applied magnetic fields. 3) The design of active polymeric materials and implementation of their use as seals in hydraulic and pneumatic systems. The focus of the mechanical system monitoring research is the processing of signals generated in noisy environments, for example signals from micro- and nano-size sensors operating in macro-size systems so that noise levels are expected to be much larger than sensor resolution. The magnetic treatment work is aimed at using pulsed magnetic fields to improve characteristics of manufactured parts, e.g., reduction of residual stress. Since magnetic fields can alter material properties, they can be used to change the operation of mechanical systems. As an example of this kind of process control, the modification of bearing race hardness by applying pulsed magnetic fields to operating bearings has been demonstrated. Polymeric materials are being designed at the basic structural level so as to produce desirable behavior in response to mechanical stress and environmental factors. The first application being pursued is elastomeric materials for use in adaptive O-rings that respond to leak causing effects by counteracting the effects with useful changes in material behavior.

Teaching

With the intent of adding to teaching resources Prof. Klamecki is developing computer-based exercises to accompany textbooks on manufacturing processes. The rationale in the development of these exercises is that they should provide a means of study and learning that cannot be implemented with traditional, paper textbooks. The ability of programs to provide interactivity and some degree of customization is being exploited. Some of these exercises, along with more details of research work and results, are available at the link below.
