Abstract

The escalating demand for sustainable energy solutions within the automotive industry has catalyzed extensive research into alternative methodologies for energy harvesting. This investigation examines the feasibility of thermoelectric energy harvesting from disc brake systems utilizing the SP1848-27145 SA thermoelectric generator (TEG) module. The selection of the SP1848-27145 SA module is predicated on its dependable electrical output when subjected to moderate temperature differentials characteristic of disc brake operations, in conjunction with its compact and lightweight configuration, which renders it amenable for integration into vehicles.A laboratory-scale apparatus emulating a disc brake system was constructed, and a series of experimental tests alongside computational simulations were conducted to assess the efficiency of the conversion from thermal to electrical energy. Braking loads ranging from 1.5 to 2.25 kg were exerted over intervals of 50 seconds, resulting in disc temperatures ascending to 114.8 °C. The maximum output voltage recorded was 0.57 V. Numerical simulations executed with ANSYS 19.2 corroborated the experimental findings, exhibiting a deviation of less than 1%. The maximum power output realized was 185.4 mW under optimal conditions, with a conversion efficiency fluctuating between 4% and 6%.These results underscore the potential applicability of TEGs in facilitating micro-energy systems within the automotive sector. Furthermore, the findings suggest that enhancements in thermal interfaces and optimized cooling techniques could enable this configuration to function as a sustainable auxiliary energy recovery system for hybrid and electric vehicles.

Abstract

Proses metal spinning merupakan metode pembentukan logam yang banyak digunakan untuk menghasilkan komponen berbentuk simetris dengan efisiensi material tinggi. Namun, kualitas produk yang dihasilkan sangat dipengaruhi oleh parameter proses, khususnya kecepatan putar spindle, yang berpengaruh terhadap distribusi ketebalan, deformasi plastis, dan kekasaran permukaan. Penelitian ini bertujuan untuk menganalisis pengaruh variasi kecepatan putar spindle terhadap perilaku deformasi, uniformitas ketebalan, distribusi thinning, dan kualitas permukaan pada proses metal spinning Aluminium 1100 serta menentukan kondisi proses optimum. Metode penelitian menggunakan pendekatan eksperimen kuantitatif dengan variasi kecepatan 320 rpm, 500 rpm, 900 rpm, dan 1120 rpm. Pengukuran ketebalan dilakukan pada lima titik pengamatan (T1–T5), sedangkan kualitas permukaan dievaluasi menggunakan parameter kekasaran permukaan (Ra). Analisis data dilakukan menggunakan parameter statistik berupa rata-rata, standar deviasi, dan koefisien variasi, serta didukung analisis regangan sejati, model Hollomon, dan Forming Limit Diagram berbasis model Marciniak–Kuczynski. Hasil penelitian menunjukkan bahwa kecepatan 900 rpm menghasilkan distribusi deformasi paling homogen dengan ketebalan rata-rata sebesar 0,88 mm dan nilai koefisien variasi terendah sebesar 4,59%. Sementara itu, kecepatan 1120 rpm menghasilkan kualitas permukaan terbaik dengan nilai Ra sebesar 1,32 µm, namun meningkatkan thinning hingga 28% pada titik kritis T3. Berdasarkan keseluruhan hasil, kecepatan 900 rpm direkomendasikan sebagai kondisi optimum karena memberikan keseimbangan terbaik antara stabilitas deformasi, uniformitas ketebalan, dan kualitas permukaan.
