Preliminary design analysis and fabrication of MYSAT structure / Mohammed Hazrieq Hasief Amir

Abstract MYSAT adalah satelit pertama yang pernah di mana dibina oleh pelajar universiti dari (Universiti Sains Malaysia) USM. Subsistem struktur MYSAT direka khusus untuk menyokong misi MYSAT. Dimensi luaran iaitu CubeSAT mesti serasi dengan antara muka deployer, yang dalam kes ini adalah Eksperimen Jepun Modul kecil Satelit Orbit Deployer (J-SSOD). Di samping itu, struktur iaitu CubeSat juga perlu menjalani beberapa analisis struktur seperti yang dikehendaki oleh pemberi perkhidmatan J SSOD, Jepun Aerospace Exploration Agency (JAXA). Tesis ini memberi tumpuan kepada reka bentuk casis MYSAT untuk mendapatkan hasil keperluan struktur subsytems ini mengikut objektif misi. Struktur ini telah direka dan dibina oleh pencetak 3D dan kemudian CNC Mesin untuk memeriksa kelemahan reka bentuk dan kesesuaian pemasangan dan proses pembuatan. Analisis struktur juga telah dilakukan ke atas model yang menggunakan ANSYS untuk menunjukkan keupayaan struktur MYSAT untuk menahan beban. Dua jenis casis telah dikaji iaitu bingkai modular dan monoblock. Hasilnya menunjukkan bahawa monoblock mempunyai kekerapan yang lebih tinggi dalam analisis modal 219.52Hz bandingkan dengan bingkai modular yang 247,32. pendekatan Monoblock menawarkan hubungan terbaik antara ketegaran dan besar-besaran tetapi mempunyai kelemahan ketara meningkatkan kerumitan prosedur pemasangan.Pada akhir karya ini, akan ada cadangan beberapa masa depan untuk kajian akan datang dalam hal projek ini. _______________________________________________________________________________________________________ MYSat is the first satellite ever in which is built by the university student from (Universiti Sains Malaysia) USM. The structural subsystem of MYSat is specifically designed to support the mission of MYSat. The external dimension of the CubeSat must be compatible with the deployer interface, which in this case is the Japanese Experiment Module Small Satellite Orbit Deployer (J-SSOD). Besides, the CubeSat structure must also undergo several structural analysis as required by a J-SSOD service provider, Japan Aerospace eXploration Agency (JAXA). This thesis focuses on the chassis design of MYSat to refine structure subsystem’s requirements according to the mission objectives. The structure has been designed and fabricated by 3D printer and then CNC Machine to examine the design flaws and fitting and suitability of manufacturing process. The structural analysis has also been performed on the model using ANSYS to demonstrate the ability of MYSat structure to withstand the loads. Two type of chassis have been studied which is modular frame and monoblock. The result shows that monoblock have higher frequency in modal analysis 219.52Hz compare to modular frame which is 247.32. Monoblock approach offers the best relationship between rigidity and mass but has the disadvantage of significantly increase the complexity of assembly procedures. Lastly, at the end of this work, there will be a few future recommendation for future research in regards to this project.
