TAN PRESSURE MONITORING UNTUK MENENTUKAN INDICATED HORSE POWER (IHP) PADA MESIN DIESEL
Get PDFSecara umum mesin diesel tidak berbeda jauh dengan mesin bensin. Beberapa bagian komponennya mempunyai fungsi yang sama dengan mesin bensin. Perbedaan utamanya pada proses atau siklus kerja. Mesin diesel tidak menggunakan pengapian untuk memulai pembakaran.Bahan bakar diinjeksikan ke dalam ruang bakar pada akhir langkah kompresi. Sebelumnya udara yang diisap telah dikompresi dalam ruang bakar sampai tekanan dan temperatur menjadi naik mencapai 900 – 1000oC. Naiknya tekanan dan temperatur mengakibatkan bahan bakar menyala dan terbakar sendiri. Untuk mengetahui besar tekanan hasil pembakaran bahan bakar dipasang presure monitor yang terhubung dengan sistem proses dari analok menjadi digital dan diproses lagi dalam bentuk grafik fungsi tekanan. Sedangkan untuk mengetahui besar sudut dari motor diesel tersebut dipasan sistem kontrol untuk mengetahui besar sudut pada poros engkol yang juga terhubung dengan komputer sebagai fungsi sudut engkol. Dari dua sistem monitor tersebut terbentuklah grafik fungsi tekanan dengan sudut engkol pada motor diesel.Dari hasil pengambilan data pada motor diesel Merk Mitsubhisi type 4D32-04 dengan 4 silinder diperolah tekanan maksimun pada tiap tiap silinder rata –rata tertinggi adalah sebesar 76.11 kg/cm2, Sehingga dari hasil olah data diperoleh Indicated Horse Power (IHP) dari motor diesel tersebut adalah 82.93 PS pada 2750 rpm. Kata kunci- Tekanan, Hp, Mesin Diesel, Monitoring, Indikasi H
DESAIN TULANGAN LENTUR PELAT PADA STRUKTUR FLAT PLATE BER-HOLLOW ¬DUA ARAH DENGAN METODE LEBAR EFEKTIF
Get PDFUntuk mendesain tulangan pelat pada struktur flat plate ber-hollow dua arah perlu penyederhanaan dari bentuk distribusi tegangan yang terjadi, caranya adalah dengan memanfaatkan lebar efektif dari column strip area dan middle strip area, dengan cara ini bentuk momen yang berkontur 3-dimensi diubah menjadi lembaran-lembaran 2-dimensi yang sederhana. Metode desain tulangan memanfaatkan lebar efektif pelat dari struktur flat plate ber-hollow dua arah yang menggunakan hollow berbentuk trapesium, selanjutnya tegangan pelat yang sebelumnya tidak merata didistribusikan merata pada lebar efektif pelatnya dengan konsep redistribusi momen. Hasil desain lentur dengan menggunakan tulangan ber-diameter 13 mm maka diperoleh spasi terkecil dan terbesar pada column strip sebesar 75 mm dan 140 mm, sedangkan spasi terkecil dan terbesar pada middle strip adalah sama besar yakni 140 mm. Hal ini membuktikan bahwa tegangan pada bagian column strip terbilang lebih bervariasi, sedangkan pada bagian middle strip terbilang relatif kecil dan sama besar. Kata kunci - Lebar Efektif Pelat, Redistribusi Mome
