“…Park dkk [2] melakukan penelitian untuk mengurangi eksitasi gaya dan momen pada mesin empat langkah tujuh silinder dengan mengoptimasi sudut-sudut poros engkol dimana posisi sudut-sudut poros engkolnya tidak dibagi merata (360 derajat dibagi jumlah silinder) seperti mesin segaris (in-line engine) konvensional. Penelitian pada sistem dudukan mesin (engine mounting system) yang berfungsi sebagai peredam getaran mesin juga telah dilakukan mulai dari dudukan jenis elastomer hingga hidrolik dan dari dudukan pasif hingga aktif untuk memperbaiki unjuk kerjanya, seperti yang dikemukakan dalam kajian literatur oleh Yu dkk [6]. Pada dasarnya pada mesin dengan dua silinder segaris jika kedua piston serempak bergerak ke arah yang sama maka getaran mesin semakin besar dan jika bergerak ke arah berlawanan maka getaran mesin semakin kecil.…”

ABSTRAKGetaran dari mesin (engine) adalah salah satu sumber getaran pada kendaraan. Getaran ini disebabkan adanya variasi tekanan gas di dalam silinder dan fluktuasi gaya karena gerakan berputar dan gerakan bolak-balik komponen-komponen mesin. Penelitian ini bertujuan untuk mengetahui besar getaran dan menganalisa getaran mesin empat langkah 550 cc dua silinder segaris, dengan memvariasikan sudut antar engkol 0 o , 90 o , dan 180 o . Mesin ditumpu oleh tiga dudukan karet (rubber mounts) dengan posisi dua di depan dan satu di belakang. Penelitian dilakukan dengan membuat model dinamis mesin dalam lima derajat kebebasan. Gaya eksitasi yang bekerja pada mesin ditentukan dari tekanan gas hasil pembakaran dalam silinder dan gaya inersia bagian-bagian mesin yang berputar dan bergerak resiprokal. Input parameter-parameter lain dalam pemodelan ditentukan dari pengukuran bagian-bagian mesin yang terlibat dalam pemodelan, kemudian dilakukan simulasi model dengan software MATLAB Simulink untuk mengetahui respon getaran blok mesin dalam arah translasi vertikal (arah sumbu Y) pada variasi kecepatan putaran mesin 1000, 3000 dan 5000 rpm. Hasil simulasi menunjukkan getaran blok mesin terbesar terjadi pada posisi sudut antar engkol 180 o dan terkecil pada sudut 0 o .Kata kunci: mesin dua silinder, getaran, pemodelan dan dinamika mesin. ABSTRACT Vibration was induced by engine is one of vibration sources that occurs in the vehicle. This vibration is caused by gas pressure variation inside the cylinder and force fluctuation from rotating and reciprocating components of engine. In this study, vibration magnitude and analysis on 550 cc four stroke two inline cylinders engine by varying angle between cranks

An ideal engine mount should be able to completely isolate the engine vibration which is caused due to the engine Noise, Vibration and Harshness characteristics. Vibration in an automobile is due to different parts of the automobile, one of the main sources of vibration is the engine. In engine, the vibration is mainly due to drive trains.Hence, it is very important to optimize the engine mount to reduce vibration at the source itself, to increase the comfort of the passenger. In this paper, standard passive engines mount which is available in market is used for optimization which is fed into the Ansys for shape optimization by fixing the surface to be retained and necessary boundary condition is applied to obtain an optimized shape, both of the models i.e. standard model and optimized model is subjected to dynamic analysis to obtain the stiffness. The stiffness obtained in optimized model was less when compared with that of the standard model. Since the shape and stiffness of the mount are optimized, the vibration transferred from the engine to the compartment is reduced as well as the life of the mount is also improved.

“…For examples, HWL Scientifice Instrument GmbH (ND) and Lee, Chen, Chung, and Wang (2006) utilized both feedforward and feedback control techniques to enhance the anti-vibration performance. In Yu, Naganathan, and Dukkipati (2001), an independent two-channel controller based on velocity feedback was employed to improve the isolation from the base vibration of a mounted rigid-equipment structure. Theoretical and experimental investigations of active anti-vibration systems were also presented in Marjoram (1985) and Beard, Schubert, and Von Flotow (1994).…”

This paper presents an active anti-vibration control system with isolation of low-frequency vibration. A proper dynamic model of the anti-vibration control system is derived for controller design in that the identification scheme for a mathematic model is proposed. The model reference controls of the anti-vibration system with the sky-hook damper control and impedance control are analyzed respectively. An illustrated example of a single-degree-of-freedom anti-vibration system driven by a linear servomotor is given to verify the performance of the proposed control design. Experimental results are presented to validate that the peak resonance value of 0dB within a frequency of 10Hz can be achieved successively.
