This study is focused on development of a design algorithm for trunk lid hinges with four-bar linkage. The aim of the study is to minimize design time and costs by eliminating trial and error procedures in traditional design process of trunk lid hinges. In the study, under a task of dimensional synthesis of mechanisms, motion generation problem has been solved for realizing the movement of the trunk lid to a set of positions respectively. In order to obtain the required manual opening force of the trunk lid, the equations of position and static force analysis of the four-bar hinged system have been derived. Using the equations and mathematical models so obtained, design algorithm codes have been developed in Hypermath program. For determining the optimum values of parameters of the system, an optimization study was carried out in Hyperstudy program by using the developed algorithm codes. At the last stage, kinematic analysis of the system was performed in Motionsolve program to validate the mathematical models, algorithm codes and optimization study. At the end of the study, the results obtained from optimization study were found to be accurate and valid according to kinematic analysis.
