In this paper was studied the design of feeding material system using four bars linkage mechanism. It was carried out dimensional synthesis of the mechanism based on the complex number method. This synthesis is applied to determine the length of crank, coupler, follower and dyad that control of feeding weight. Base on the results, it is obtained that the dimension of the four bars linkage and dyad to control 250 kg weight of feeding material reprsented by lengths of crank, coupler and follower are 1 m, 2 m, and 1 m rspectively and two links of dyad 0.2 m and 0.75 m. It was also determined the constant of spring to support the opening of the feeding material, 23,18 kN/m and input torque, 1083 Nm.

In this paper we discussed the forward kinematic and constrain error of 3-URU parallel mechanism. The mechanism was composed of URU kinematic chain consisting of three parallel joint axes and two intersecting joint axes. The direction of parallel joint axis representing direction of force constraints acting on center of platform rotation. In this research was investigated the effect of error of direction of parallel joint exes on kinematic chains to the platform orientation and position of center of platform rotation. It is also developed the formulation of forward kinematic of the mechanism. The forward kinematic was carried out by taking account geometric constraint of platform motion which is derived analytically by using software Maple 16. On the other hand, the constraint error was evaluated using the CAD simulation Autodesk Inventor. Based on the result, it can be summarized that error of parallel joint axes produced significant effect on error of platform motion especially for location of the center of platform rotation which is classified as uncompensated error. The formulation of forward kinematic was successfully derived which is confirmed with inverse kinematic and CAD simulation.

Analisis Respon Landing Gear pada Pesawat Tanpa Awak Saat Mendarat Lovely Son; Firman Zain; Mulyadi Bur

Penelitian ini membahas tentang analisis respon dinamik pada landing gear pesawat tanpa awak saat mendarat. Penelitian diawali dengan pemodelan mekanisme landing gear untuk mendapatkan harga kekakuan dan redaman ekivalen. Penurunan persamaan gerak dilakukan dengan asumsi sistem getaran satu derajat kebebasan. Respon sistem dihitung dari persamaan gerak secara analitik. Simulasi numerik dilakukan untuk mendapatkan grafik respon simpangan dan percepatan. Evaluasi respon sistem dilakukan untuk sejumlah variasi dimensi batang dan kekakuan pegas pada mekanisme landing gear. Dari hasil simulasi ditunjukkan bahwa harga maksimum amplitudo respon percepatan berbanding terbalik dengan harga maksimum amplitudo respon simpangan. Disamping itu, peningkatan harga kekakuan pegas ks menyebabkan meningkatnya harga maksimum respon percepatan dan mengurangi amplitudo respon simpangan pada landing gear.
