Analysis and Optimization of Rotor Housing Assembly

Abstract

The paper presents analysis and optimization of the sonic drill head rotor housing assembly. The project was initiated by Layne Christensen DTC and performed at Purdue University Calumet in cooperation with the company engineers. Full finite element (FE) models of the rotor housing assembly were developed. Real world working conditions were applied onto the FE models in Ansys Workbench. With different Material setups, multiple trials were simulated so that the performances of material changes can be observed. Results of the total deformations were collected and analyzed both graphically and numerically. Based on the analysis results, recommendations on optimization of the rotor housing assembly were provided. A proposed new design was also developed and analyzed, and a numerical comparison of the new and original designs were made to give the company further recommendations. Support of Layne Christensen DTC is greatly appreciated.
