Equipment such as a rod between vehicle body and
hood or a lift strut are used to keep automobile hood in open positions during
the regular maintenances or repairs. Moreover, some effort is required to open
or close automobile hood because of its weight. To keep it in various opened positions
and to exert the least force to open or close it, a mechanism is used in
conjunction with extension, compression or torsion springs in two different
configurations. Each optimization has been carried out for all these different
springs, each in two configurations and results are compared. Sensitivity
analysis for the design variables are examined to determine how these variables
are influential on the designed mechanism. Optimization results of extension
and compression springs are observed to be similar in both configurations of
the designed mechanism. On the other hand, results for the torsion spring in
two configurations are exactly the same for the mechanism. Sensitivity analysis
shows that the designed mechanism is not sensitive on the design variables that
are on the bound in both of these two configurations.
