Abstract

This study provides a comprehensive analysis of the characteristics of MR mounts in squeeze mode which is the least commonly-analyzed aspect of MR fluids. The results of the study are based on a novel rheometer that is designed and fabricated for the purpose of better understanding the characteristics of MR fluids in squeeze mode. The paper describes the details of the rheometer design. It further provides the test results for MR fluids tested in squeeze mode. The tests indicate a clumping effect of the fluid when tested in repeated cycles that does not appear to have been documented previously. The paper describes, in detail, the clumping effect and provides possible reasons for this phenomenon.
