Thermo-structural brake squeal FEM analysis considering temperature dependent thermal expansion
Abstract eng: During the process of evaluation of disk brake components for brake squeal occurrence using computational methods, invariance of material properties according to temperature is commonly considered. This approach is not usually in correlation with experiments and user experience. Paper focuses on study of thermal expansion coefficient variation of the friction material and its influence on brake squeal occurrence and propensity. Study has been done experimentally on simplified pin-on-disk system and also numerically using FEM procedures. Computational FEM model capable of time history thermo-structural evaluations and Complex Eigen Value calculation has been brought to study upper mentioned effects.
