Pemilihan Material dan Desain yang Inovatif serta Kreatif

Material selection and innovative and creative designs are needed as a medium for reducing production costs by changing the design of a product but still paying attention to the safety of its users. The problem that occurs in the surrounding community is the lack of public knowledge about the selection of materials that can risk accidents that will be experienced by users which can be caused by the material not being strong enough to support the load it gets. Innovative and creative design aims to reduce the mass of the material but still refers to user safety. Inappropriate design can increase the risk of accidents and wasted costs in the production process. The method used in this community service is a material selection workshop and an introduction to machine design using solidworks software. Therefore, this community service will greatly help the community in the Karang-tempel Village, East Semarang District, increase their insight into the selection of materials and innovative designs as an increase in the quality of production and ensure the safety of users.

Permasalahan yang terjadi di masyarakat sekitar akan kurangnya pengetahuan masyarakat tentang pemilihan material yang dapat berisiko akan terjadinya kecelakaan yang akan dialami pengguna yang dapat disebabkan oleh material tidak cukup kuat untuk menopang beban yang didapatkannya. Desain yang inovatif dan kreatif bertujuan sebagai pengurangan massa dari material akan tetapi tetap merujuk kepada keselamatan pengguna. Desain yang tidak sesuai dapat meningkatkan risiko kecelakaan dan pemborosan biaya pada proses produksi. Metode yang digunakan pada pengabdian masyarakat ini adalah workshop pemilihan material dan pengenalan rancang bangun mesin menggunakan software solidworks. Oleh karena itu pengabdian kepada masyarakat ini akan sangat membantu mas-yarakat di lingkungan kelurahan Karang-tempel, kecamatan Semarang Timur untuk menambah wawasannya terhadap pemilihan material dan desain yang inovatif sebagai peningkatan kualitas hasil produksi dan menjamin keselamatan dari pengguna.Kata kunci: desain; inovatif; kreatif; pemilihan material; workshop

Methods of optimisation in machine design

The paper is devoted to the problem of optimal machine design selection by developing and solving the problem of multi-criteria optimisation, using the method suggesting a unified criterion with the use of weighting factors based on expert estimates. Based on the example of the design of a multi-purpose machine for service electric transport, a mathematical model of parametric optimisation of the design of electric and combined propulsion plants is developed. The most efficient system components are selected to meet the customer's requirements.

Rancang Bangun Mesin Pemipil Jagung Dua Silinder menggunakan Motor Listrik

<p class="icsmheading1"><em>Seeing the situation of animal feed needs which tend to increase every year, it must be accompanied by the procurement of production machines to reduce the productivity of corn. Corn sheller machine is a tool that serves to release corn kernels from the cob. Along with technological developments that continue to progress, many production machines have sprung up such as corn shellers ranging from those that are operated manually to automatic. Each machine has different advantages and disadvantages. In the design of this corn sheller machine the main driver uses an electric motor. The design of this corn sheller machine aims to help ease the burden on corn farmers in particular. At first the corn shelling was done manually, then it developed using a large selep machine but the costs incurred were relatively expensive. The design of a two-cylinder corn sheller machine uses an electric motor to determine the appropriate design and construction of the corn sheller machine. In this machine there is no corn diameter limit for the shelling process in other words this machine is designed for all sizes of corn. In this design using several stages, namely first planning the design of the engine frame, electric motor, pulley and v-belt ratio and the calculation of the shaft. The result of the design is a machine design that is 1200 mm long, 1200 mm wide and 800 mm high. The sheller machine is driven using an electric motor of 500 watts, Rpm 1400 with a transmission system using a pulley and a v-belt ratio of 1: 1. There is no limit to the diameter of corn kernels in the shelling process using this machine. So it can be concluded that this machine has an effective design and sufficient shelling results, able to reduce post-harvest costs for corn farmers.</em></p>

КІНЕТОСТАТИЧНЕ ДОСЛІДЖЕННЯ ШАРНІРНИХ ПРОСТОРОВИХ МЕХАНІЗМІВ ГАЛТУВАЛЬНИХ МАШИН (ЧАСТИНА 1: ДОСЛІДЖЕННЯ МЕХАНІЗМУ З ДОДАТКОВОЮ РУХОМОЮ ЛАНКОЮ – КОРОМИСЛОМ)

Kinetostatic study of a statically determined hinged spatial mechanism without redundant (passive) connection with an additional movable link – a rocker arm of a machine for processing parts, in which the working container performs complex spatial movement. Methodology. The essence of the kinetostatic research was to determine the radial and axial components of the reactions in all rotational kinematic pairs of the hinged statically defined spatial mechanism of the machine for processing parts, when it is idling. The kinetostatic study was implemented using the SolidWorks 2016 computer-aided design system with preliminary 3D modeling of this machine design with an additional moving link – a rocker. Results. In the course of the kinetostatic study, 3D modeling of a machine with an additional movable link – a rocker arm in the SolidWorks 2016 computer-aided design system was carried out, the maximum values of the radial and axial components of reactions in all rotational kinematic pairs of the machine for processing parts were determined, the effect of changing the center distance of the intermediate connecting rod (working capacity ) on the increase in the maximum values of the reactions in all rotational kinematic pairs. Scientific novelty. The relationship between the center distance of the intermediate connecting rod (working capacity) and the change in the maximum values of the reactions in all rotational kinematic pairs of the machine for processing parts is determined. As a result, it becomes possible to determine the maximum permissible center distance of the intermediate connecting rod to ensure the durable operation of the machine. Practical significance. It is determined that the nature of the change in the maximum values of the radial and axial components of the reactions in each rotational kinematic pair of the spatial mechanism depends on the value of the coefficient characterizing the ratio of the center-to-center length of the intermediate connecting rod (working capacity) to the center-to-center length of the driving or driven connecting rods of the machine. The range of variation of this coefficient has been determined, within which it is rational to design this machine design. The results obtained can be used in the corresponding design bureaus of machine-building enterprises at the stage of designing tumbling equipment with a complex spatial movement of working containers.
