Abstract

In this study, a software has been improved for parametric drawing and modeling of spur gear using complex numbers in the CAD setting. AutoLISP programming language was used in software development. In the system, parameters such as module and number of teeth can be entered by the user and drawing or modeling of the gears in the CAD environment can be done automatically. This study provides the designer with fast and functional and more precise utility alternative for gear drawing and modeling. In addition, within the scope of the study, the same number of teeth and at the module spur gear were designed in the AutoCAD package program with the classical method. Spur gears, designed in AutoCAD program with the developed package program and classical method, were produced on the wire EDM machine by deriving cutting codes in the MasterCAM program. Noise analysis of the produced spur gear pairs has been made. It was determined that the spur gear pair, designed and produced with the package program developed within the scope of the study, operates approximately 8 dB less noise than the spur gear designed and produced with the classical method. It is possible to design and manufacture the gear in the desired profile by changing the cutter profile for non-standard thread shapes to provide the performance required for a tool and standard tool parameters. For further investigations, spur gears produced by round-ended cutters can be applied symmetrically and asymmetrically., Bu çalışmada, CAD ortamında karmaşık sayılar kullanılarak düz dişlilerin parametrik çizimi ve modellemesi için bir yazılım geliştirilmiştir. Yazılım geliştirmede AutoLISP programlama dili kullanılmıştır. Sistemde modül ve diş sayısı gibi parametreler kullanıcı tarafından girilerek CAD ortamında dişlilerin çizimi veya modellemesi otomatik olarak yapılabilmektedir. Bu çalışma, tasarımcıya dişli çizimi ve modellemesi için hızlı, işlevsel ve daha kesin bir fayda alternatifi sağlamaktadır. Ayrıca çalışma kapsamında klasik yöntemle AutoCAD paket programında aynı sayıda diş ve modülde düz dişli tasarlanmıştır. Geliştirilen paket programı ve klasik yöntemle AutoCAD programında tasarlanan düz dişliler, MasterCAM programında kesme kodları türetilerek tel erozyon makinesinde üretilmiştir. Üretilen düz dişli çiftlerinin gürültü analizi yapılmıştır. Çalışma kapsamında geliştirilen paket program ile tasarlanan ve üretilen düz dişli çiftinin, klasik yöntemle tasarlanan ve üretilen düz dişliye göre yaklaşık 8 dB daha az gürültü çalıştığı tespit edilmiştir. Bir takım ve standart takım parametreleri için gerekli performansı sağlamak üzere standart dışı diş şekilleri için kesici profilini değiştirerek dişliyi istenen profilde tasarlamak ve üretmek mümkündür. Daha ileri araştırmalar için, yuvarlak uçlu kesicilerle üretilen düz dişliler simetrik ve asimetrik olarak uygulanabilir.

Abstract

In this study, it was aimed to determine the forces and torques acting on the shoulder and elbow joints of the upper limbs, which are the most commonly used body parts in daily life. The subject was asked to take a certain load on the table while standing upright, bring him closer to himself and leave it back. A dynamic model was created using the Newton-Euler method to determine the joint force and torque occurring in the shoulder and elbow during the movements performed by the selected subject while performing this task. Wearable motion sensors were used to measure the location data of the joints. The torque and link force values in the joints were calculated using the dynamic model created with the motion data received from these sensors. The calculation results obtained were evaluated comparatively and it was revealed in which cases the forces and torques acting on the joints increased and what measures could be reduced.

Abstract

In this study, the effects of vehicle vibrations on driver comfort are examined in terms of the magnitude of the vibration transmitted to the internal organs. For this purpose, a half car model was created with the vehicle seat and the driver with the internal organs. While the vehicle and its seat have 5 degrees of freedom, the driver is modeled as 4 degrees of freedom, and as a result, a system with a total of 9 degrees of freedom has been modeled. The bumps used as speed regulators on the roads are accepted as vibration input to the system while writing the equations of motion. Simulations were performed for different vehicle speeds and different bumper dimensions to evaluate the vibrations transmitted to the driver's head, internal organs and the driver's seat. When assessing the magnitudes of the vibrations transmitted to the internal organs, the root mean square is used. In the literature, suspension and driver seat designs take the criterion of reducing the vibration transmitted to the driver's seat, while few are based on the acceleration of the vibration transmitted to the driver's head. In this study, it is proposed to take into account the root mean square value of the vibration transmitted to both the head and internal organs of the driver in suspension, seat and bump designs.

Günümüzde teknoloji alanında çok hızlı gelişmeler olmaktadır. Bu gelişmelerin hayata geçirilebilmesi için eğitim kaçınılmazdır. Bu çalışmada, teknolojide önemli bir yeri olan otomasyon sistemlerinde kullanılan Programlanabilir mantıksal kontrolör (PLC) eğitimi için kartezyen robot sistemi gerçekleştirilmiş ve bir eğitim seti oluşturulmuştur.Çalışmada, PLC kontrolörlü kartezyen robotun gerçek zaman çalışmasında 2 ile 5 [mm] arasında hata değerine neden olduğu saptanmış ve bunun nedenleri irdelenmiştir. Kartezyen robot sisteminin PLC eğitiminde kullanılabileceği, bunun eğitimini alan kişilerin tasarlama, problem çözme yeteneklerini geliştirmelerine katkı sağlayabileceği sonucuna varılmıştır. Today, rapid developments in the field of technology have been happening. The training is unavoidable for realization of those developments. In this work, a cartesian robot system has been realized for the training of a Programmable Logic Controller (PLC) used in automation systems that are an important place in technology.In this work, error values in a variety of tasks done by the training set in the range of 2 and 5 [mm] have been found in real-time applications of the cartesian robot with PLC and causes of those errors have been discussed. It has been resulted that this cartesian robot system will enable to be used in the training of PLC and will give contribution to the people for training in developing the ability of problem solving and designing. 225
