Sistem suspensi merupakan komponen penting dalam kendaraan, karena berfungsi sebagai peredam getaran bagi kendaraan ketika dikendarai oleh penggunanya. Ada beberapa jenis sistem suspensi yang diterapkan pada kendaraan. Salah satu komponen yang paling penting dalam meredam getaran adalah karet. Pembuatan suspensi karet dimulai dari perencanaan. Perencanaan ini meliputi proses desain dan pemilihan material. Desain karet menggunakan software autodesc inventor dengan memperhatikan kekuatan karet. Desain lebih menitik beratkan pada kekuatan karet ketika menerima beban. Lori inspeksi dirancang dengan kecepatan operasional 20 Km/jam dan kecepatan maksimum 25 Km/jam. Pemilihan bahan dengan menggunakan beberapa campuran bahan kimia dan karet alam yang dominan untuk menambah kekuatan karet. Pembuatan karet dilakukan di tempat industri karet CV Juwahir Berdikari yang berada di Gorang gareng kabupaten Magetan. Dengan beberapa tahapan proses yang membutuhkan mesin khusus untuk menghasilkan produk dari karet. Proses produksi tersebut dimulai dari pencampuran komposisi bahan karet, penyiapan cetakan karet, dan pengepresan kemudian finishing. Hasil dari pembuatan karet akan dipasang di chasis lori inspeksi.

One of the major factors in an economic project of new concrete dams and safety valuation of available dams in seismic areas is the control and dissipation of the induced hydrodynamic pressure induced by dam and reservoir interaction. As one of the main control functions, dissipating the induced hydrodynamic pressure on the upstream face of the dam is considered in the evaluations. In this paper, the effects of a rubber damper as an isolation layer on the dam's seismic control have been investigated. For optimization of the rubber damper thickness and height, the Monte Carlo probabilistic analysis is used. The ANSYS program on the basis of finite element technique is applied for modeling and analysis. The Pine Flat dam in California, due to components of El Centro, San Fernando and North Ridge earthquake is modeled as a case study to evaluate the effect of upstream isolation layer on seismic control and optimization. The effect of the thickness and height of the rubber damper on reducing the responses is investigated and the optimum thickness and height are selected using sensitivity analysis for safe and economic design. The obtained results show the capability of the rubber damper in the seismic and hydrodynamic control of the sample model.

Torque Behavior

Abstract Automobile components are subjected to high dynamic loads and vibrations under operational conditions which needs detailed system analysis for work properly. The torque generated in the engine creates oscillations, and this case occurred at different levels of frequencies. Clutch is one of the important part of automobile powertrain system with torque transmission controlling and vibration damping properties. Metallic helical springs are widely preferred within the clutch discs with their durable mechanic properties against dynamic variables on an automobile. This study develops the novel approach on the time-based investigation of rubber clutch springs, and system optimization for torsional vibration damping using the simulated annealing algorithm method. In this purpose, the torque behavior of the rubber spring instead of the helical spring was investigated by experimentally in time-dependent manner. Rubbers consist of polymer chains which are highly sensitive to dynamic variables such as operation time, frequency and thermal load. The clutch disc which includes rubber damper spring made of NBR (Nitril rubber) is experimentally tested with functional torque measurement at different compression cycle times to observe rubber damper spring viscoelastic time-based behavior. As the next step, 1-D modeling of powertrain system, including rubber clutch damper springs, were subjected to vibration optimization with simulated annealing (SA) algorithm. Thus, the simulated annealing (SA) algorithm was developed, and integrated run is provided with 1-D modeling for optimization in Python script. This methodology accelerates the powertrain system optimization using both rubber and metallic damper types with eliminating many of real vehicle testing and saving cost and time before the production phase. Also, results give an idea on the importance of 1-D simulation before design modeling of rubber clutch damper system based on time-dependent conditions.
