Abstract

Penilaian kinerja struktur sasis kendaraan berkaitan dengan kekuatan dan kekakuannya untuk mencapai tingkat yang cukup dengan massa sesedikit mungkin. Kekuatan struktur sasis kendaraan dirancang mampu menahan beban yang diberikan mencakup semua sub komponen kendaraan. Jalur beban dalam struktur sasis disesuaikan dengan identifikasi komponen dan kebutuhan pembebanan. Sedangkan implementasi elemen rangka digunakan seleksi material dan komponen dengan metode elemen hingga untuk menghitung kemampuan kendaraan menangani perpindahan kondisi pembebanan pada struktur sasis. Pada tesis ini prosedur desain untuk meningkatkan kekuatan struktur sasis pada bagian yang mengalami tegangan dan kepadatan energi regangan maksimal dikembangkan dan direpresentasikan dalam detail engineering design. Pemilihan ukuran elemen pada proses meshing didasarkan pada akurasi dan tujuan dari hasil mode deformasi. Analisa statis diterapkan pada sistem untuk mengetahui reaksi dari beban, tegangan dan regangan dalam struktur. Analisa modal digunakan untuk mendapatkan natural frekuensi, mode getar dan fungsi respon frekuensi. Modifikasi desain dilakukan untuk menambah kekakuan dan kekuatan struktur berdasarkan identifikasi ratio faktor partisipasi dan kerapatan energi regangan memberikan ide perubahan desain. Evaluasi respon dinamis dilakukan dengan memodelkan permukaan jalan pada Matlab Simulink dan Script dengan luaran data PSD untuk analisa getaran acak pada Ansys sehingga desain kendaraan bisa diketahui terkait kenyamanan dansiklus hidupnya.

The performance assessment of the vehicle chassis structure relates to its strength and rigidity in order to achieve a sufficient level with as little mass as possible. The strength of the vehicle chassis structure is designed to withstand a given load covering all sub-components of the vehicle. The load path in the chassis structure is adapted to the identification of components and loading needs. While the implementation of frame elements used material selection and components with finite element method to calculate the ability of the vehicle to handle the displacement of loading conditions on the chassis structure. In this thesis, the design procedure to increase the strength of the chassis structure on the parts that experience stress and maximum strain energy density is developed and represented in detail engineering design. The selection of the element size in the meshing process is based on the accuracy and purpose of the deformation mode results. Static analysis is applied to the system to determine the reaction of the load, stress and strain in the structure. Modal analysis is used to obtain natural frequency, vibration mode and frequency response function. Design modifications made to increase the rigidity and strength of the structure based on the identification of participation factor ratio and strain energy density gives the idea of design changes. Evaluation of dynamic response is done by modeling the road surface in Matlab Simulink and Script with PSD data output for random vibration analysis in Ansys so that the design of the vehicle can be known related to comfort and life cycle.
