ANALISIS ELEMEN HINGGA BERBASIS ANSYS PADA SAMBUNGAN BAUT STRUKTUR COOLING TOWER
Abstrak
Cooling tower merupakan komponen penting dalam sistem pendinginan industri yang berfungsi untuk menghilangkan panas dari fluida kerja. Salah satu elemen utama dalam struktur cooling tower adalah baut yang menghubungkan berbagai komponen dan berperan dalam menahan beban mekanis. Studi ini bertujuan untuk melakukan pemodelan dan simulasi numerik terhadap baut dalam struktur cooling tower guna memahami distribusi tegangan dan deformasi yang terjadi di bawah beban operasional. Simulasi dilakukan menggunakan metode elemen hingga berbasis perangkat lunak ANSYS dengan penerapan gaya pretensi sebesar 200 Nm dan beban termal 40 °C. Hasil simulasi menunjukkan tegangan maksimum sebesar 0,327 MPa pada area kontak kepala baut dan pelat penghubung, serta deformasi total mencapai 5,08×10⁻⁵ mm. Konsentrasi tegangan yang muncul berpotensi menyebabkan kegagalan kelelahan pada sambungan. Studi ini memberikan wawasan yang berharga dalam optimalisasi desain dan pemilihan material baut untuk meningkatkan ketahanan cooling tower terhadap beban operasional.
