Development and analysis of a new component test for a sliding door system

Sun, Minghao, Chen, Xianyang, Kuai, Le January 2015 (has links)
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.

Simulation of electric machine in test rig

Hagström, Marcus, Jaris, Peter January 2023 (has links)
Electrification is a trend that is on the rise within the aviation industry. Electrifying more systems in airplanes leads to increased efficiency and safety. GKN Aerospace intends to simulate electric machines as a preliminary step before conducting real-world experiments for the purpose of testing different machine designs. A simulation of an existing electric machine was made in this project seeking to replicate the characteristics of a synchronous machine installed in a test rig at GKN Aerospace. The simulation was made possible by measuring and estimating parameters from the machine. Furthermore, the report demonstrates the complexity of reverse-engineering an existing machine and how unexpected challenges made the development of the simulation model much harder than anticipated. The result confirms that a simulation model can be made by measuring and estimating the machine’s parameters. However, to get a more precise simulation, more exact measurements must be done, and more time to experiment with the input and output data in Motor-CAD. The simulation developed in this project can be applied to simulate steady-state behavior of the machine. A suggestion for future work includes more detailed measurements as well as further integrating the simulation in other software platforms to facilitate more dynamic simulations.
