Abstract EN
The elastomeric diaphragm is widely used in pneumatic vibration isolators, and the relevant model is often ignored due to its complexity.
Considering that the ignored model of the elastomeric diaphragm in pneumatic vibration isolators plays an important role in the discrepancy between the predicted and practical behavior, this paper develops an analytical model for the elastomeric diaphragm using the Mooney-Rivlin modeling method and elastomeric theory.
Specifically, the elastomeric diaphragm consists of several segments in the axial section.
After considering the structural restriction, each segment can be simplified as uniaxial stretching, and the force-strain equation can be established for each segment.
By combining the equations of all segments, an analytical model of the elastomeric diaphragm can be built and solved via numerical methods.
The developed model is added to the standard model of pneumatic cylinders to supply a complete analytical model for pneumatic vibration isolators.
The experimental results demonstrate that the analytically predicted behavior is similar to the practical behavior.
The proposed analytical model can be used as a guide for the parameter design of pneumatic isolators in practice.
