Abstract
Rubber boots are used in automotive and process industries to protect the flexible connection between two components. The property of the boot should have enough stiffness to retains its shape, but not be so stiff that the interference with the flexible connection. The rubber boots are designed to accommodate the maximum possible swing angles at the joint and to compensate for changes in the actuating shaft length. If the boot is not properly designed without considering the type of applications, and swing angle and actuating length, it will get fail during the operation. Since the boot is made of hyperelastic material (rubber), it consists of geometry nonlinearities (large strain and large deformation) and nonlinear material behavior (hyperelastic) and contacts non-linearity (changing the status). This paper will describe the boot failure modes and improvements using numerical analysis and experimental methods.
