| Summary: | <p align="justify"> Transportation accidents especially land transportation are increasing in this recent years with a lot of victims. To reduce the effect of accident, crashworthiness system can be applied to the transportation, which is impact absorber module. Impact absorber module is a system that is designed to absorb the impact energy cause by crash accident by making a lot of deformation of the structure. In this final assignment, research and development of axial folding impact absorber will be done. There are two design models, collapsible part model 1 and model 2, that installed in crumple zone. <br />
<br />
Crashworthiness analysis on the study conducted using numerical simulation, which simulates a collosion between metro kapsul and rigid wall to study the characteristics of a train collosion in the extreme. The simulation will be continued with metro kapsul that has impact absorber module installed. The research is started with finite element modelling of the specimen and continued to simulation. The results of simulation is compared to literature and BS EN 15227:2008 standards to obtain a depicion of modelling performance in represents the ability of metro kapsul structure in absorbing impact energy when collosion sequence. <br />
<br />
From the result of impact analysis, it is conclude that the ability of existing metro kapsul is far from the criteria of BS EN 15227:2008. After installing collapsible part the crashworthiness parameter shows better results. Energy absortion increases from 173 kJ to 232 kJ when using the first model and 189 kJ with the second model. The deceleration changes from 10,6 g to 8,59 g with model 1 and 12,9 g with model 2. Based on the analysis, it is concluded that the design of impact absorber module should be improved in order to meet the BS EN 15227:2008 standard. <p align="justify"> |
