Abstract

Teknik penyambungan menggunakan adhesif telah banyak digunakan pada sambungan struktural material komposit atau logam untuk berbagai bidang aplikasi seperti industri kelautan, pesawat terbang, otomotif, kereta api dan konstruksi sipil. Tipe sambungan adhesif single lap joint menawarkan banyak kelebihan dalam hal penghematan waktu & biaya, memiliki karakteristik redaman yang baik, serta memberikan kekuatan yang tinggi dibandingkan teknik penyambungan konvensional lainnya. Dalam penelitian ini dilakukan analisa getaran bebas dan pembebanan statis terhadap sambungan adhesif silinder komposit tipe single lap joint menggunakan ANSYS workbench 17.1 dengan menggunakan solver modal analysis dan static structural. Optimisasi kemudian dilakukan untuk mendapatkan desain geometri yang optimal untuk optimasi kekuatan sambungan dan ketahanan vibrasi. Berdasarkan hasil simulasi didapatkan nilai shear strength dan frekuensi natural untuk setiap variasi geometri. Data hasil simulasi menunnjukkan dengan bertambahnya ketebalan dan panjang overlap meningkatkan nilai shear strength dan frekuensi natural, sehingga ketebalan dan panjang overlap merupakan parameter desain geometri yang penting terhadap kekuatan sambungan dan ketahanan vibrasi. Dalam penelitian ini disimpulkan bahwa ketebalan 2,54 mm dan overlap 70 mm merupakan geometri yang optimum dalam desain sambungan silinder komposit tipe single lap joint untuk kekuatan sambungan dan ketahanan vibrasi.

Adhesive bonding is widely used for metal or composite joining in marine, aircraft, automotive, railroad, and civil construction industry. Adhesive single lap joint offers many advantages in terms of time & cost savings, has good damping characteristics, and provides high strength compared to other conventional joint. In this study, an analysis of free vibration and static loading of cylinder composite single lap joint was carried out using solver modal analysis and static structural in ANSYS workbench 17.1. Optimization is then carried out to obtain the optimal design for optimization of joint strength and vibration resistance. Based on the simulation results, it is obtained the value of shear strength and natural frequency for each geometry variation. Simulation result shows that increasing thickness and overlap length effect the value of shear strength and natural frequency, so thickness and length of overlap are important geometrical design parameters for joint strength and vibration resistance. In this study it was concluded that the thickness of 2.54 mm and 70 mm overlap length were the optimum geometry of an adhesive single lap joint for joint strength and vibration resistance.
