The IKEA sliding door system is widely employed on IKEA’s wardrobes. In view of the massive usage of it, any optimization for reducing production costs is crucial. This work attempts to develop a special static test rig for a component of IKEA’s sliding door system. It will be used to check the quality of the component in production. The simulation-driven design method will be used in the entire process. Therefore, before proceeding with the details of the test rig, the priority should be given to the simulation. In particular, the nonlinear finite element method (FEM) will be used to identify the break load of the studied component. Finite element models were created in ABAQUS/Standard. Four kinds of POM were used to define the model’s material properties. Meanwhile the compression experiment were also conducted. Finite element models were used to predict the load capacity and compare it with the experimental results. The closest prediction in relation to the test results was 2124N, merely 6N smaller than the experimental results, giving the proof of a good finite element analysis. Based on the results of simulations and compression tests, a proper test rig consisting of a pneumatic system and load cell was selected from four concepts. The air cylinder can provide 3175N when the supplied air is 0.7MPa, which is fully met the design requirements with reasonable price.
