Rubber Damper Reinforced Steel

Introduction

In this case, a rubber damper with steel reinforced at the middle of the rubber damper block is loaded. The deformation of rubber damper reinforcement with the steel in the middle is going to be analyzed.

Expectation deformation at the end of analysis

The rubber damper block reinforcement with the steel have been draw as picture below:

Rectangular Shape Rubber Damper Reinforced with Steel

ANALYSIS

The rubber damper  reinforced with steel is then divided into 12 elements that connected together as picture below:

12-elements Constructed

CALCULATION

A few assumptions need to be considered before starting the calculation:

1. This is Plain Stress Analysis
2. The Young Modulus of Rubber is 10000 N/mm^2
3. Young modulus of steel is 200000 N/mm^2
4. The Poison Ratio of Rubber is 0.4
5. The Poison Ratio of Steel is 0.25

Input data

Loading in Y-direction : 1000kN,

Loading in X-direction : 50kN

The data inserted  into CST(Constant Strain Triangle) Software in order to calculate the deformation of the rubber damper via Microsoft Excel.

All data being put into the software via Microsoft Excel

RESULTS

The results obtained is calculated by using CST software and the results obtained is as shown in the picture below:

Final Deformation Results

Based on the results obtained above, we can construct the deformation of the rubber damper.

The blue dots represent the deformation shape after the rubber damper is loaded with the forces.

CONCLUSION

Base on the results we obtained from this analysis, we can conclude that the deformation of rubber damper mostly happen at the top side of steel reinforced.The lower body of the rubber damper and the steel experienced minor deformation.
