Modelling and structural analysis of a small-scale solid propellant test stand / Jonathan Charanraj Jeswant Singh
Pengujian roket telah digunakan oleh pengleuar rocket dan penggemar hobi rocket untuk mengukur prestasi roket secara kuantitatif. Komponen yang penting dalam pengujian rocket ialah pelantar ujian yang berfungsi sebagai pelekap rocket, pelekap peralatan ukur dan sistem penjajaran bagi roket sambil menahan tujahan roket. Oleh itu, tujuan tesis ini adalah untuk memodel dan menganalisis kekuatan pelantar ujian yang sedia ada dengan hanya mempertimbangkan analisis struktur dalam keadaan beban statik dan beban lengkokan. Skop projek ini adalah untuk mengkaji kemampuan struktur pelantar ujian dengan menganalisis pelantar ujian yang sedia ada, permodelan komponen, pemasangan komponen dah akhirnya menjalani analisis elemen terhingga untuk statik dan lengkokan di SOLIDWORKS. Dalam analisis staik and lengkokan, prosesnya melibatkan menetapkan syarat sempadan iaitu bahan, beban, dan lekapan, menghasilkan jejaring, menyelesaikan dan memproses keputusannya. Komponen yang paling diperhati ialah tiub aluminium sama ada komponen tersebuat dapat menahan tujahan yang diaplikasi padanya iaitu beban maksimum 4905N dan 9810N dalam keadaan terlampau. Keputusan menunjukkan regangan maksimum dijana di tiub aluminium mengikut rekaannya. Regangan Von Mises tertinggi ialah 235.6MPa. Nilai ini di bawah titik alah AL 6061-T6 iaitu 275MPa. Keputusan analisis lengkokan di tiub aluminium menunjukkan faktor beban lengkokan terkecil ialah 1.2661 yang mana lengkokan tidak terjadi. Selain itu, keputusan regangan utama, ketegangan, anjakan dan faktor keselamatan berada di had yang dibenarkan. Projek ini merupakan langkah pertama dalam rekaan dan fabrikasi satu sistem pengukaran tujahan yang lengkap. _______________________________________________________________________________________________________ Rocket testing has been used widely by rocket manufacturers and hobbyists alike to measure quantitatively the performance of a rocket. An essential part of rocket testing is the rocket test stand which serves as the rocket mount, measuring equipment mount and alignment system for the rocket while withstanding thrust of the rocket. Therefore, the purpose of this thesis is to model and analyse the strength of an existing test stand by only considering the structural analysis in static and buckling load conditions The scope of the project is to study the structural ability of the test stand by analysing existing test stands, modelling, assembling and carrying out FEA simulation in static and buckling load conditions in SOLIDWORKS. In the static and buckling analysis, the process involved defining boundary conditions which are material, loads and fixtures, meshing, solving and processing the results. The main consideration of structural strength was the ability of the aluminium tube to withstand the thrust exerted for the maximum load of 4905N and 9810N under extreme conditions. The results show that the maximum stress generated is at the aluminium tube as it is designed to be. The maximum Von Mises stress generated which is 235.6MPa is below the yield point of AL 6061-T6 which is 275MPa. The results for shell buckling which also occurs at the aluminium tube shows that the smallest buckling load factor is 1.2661 which predicts no buckling, Results from principal stresses, strain, displacement and factor of safety are also within allowable limits. This project serves as the first step of designing and fabricating a fully functioning thrust measurement system.
