OPTIMIZATION OF GAS SPRING DESIGN CONSIDERING FEA ANALYSIS USED IN WALL MOUNTING ARM MANUFACTURED BY REVERSE ENGINEERING PROCESS

When developing any simulation model some compromise must be made between computational efficiency and the accuracy of the model. This study gives us a fair idea for selection of gas spring parameters for the use in the wall mounting devices especially used in medical applications to mount monitors and other devices also it is useful to model the spring force of a hydro pneumatic suspension. These models are used to check the design of wall mount factor of safety which is manufactured by reverse engineering. Actual data obtained from manufacturer on a single hydro pneumatic suspension unit. The data is again compared with actual model results and correlates significantly better than the actual model. It is thus concluded that the parameters used originally are safe but can be altered to reduce weight as there is still margin for factor of safety to be reduced. So that direct manufacturing of as it is parts should be omitted in the reverse engineering process if the parameters investigated are not sensitive to errors in the spring model.
