Many studies showed the highly promising aerodynamic gain that can be obtained from using these leading-edge perturbations. The attained efficiency depends mainly on the design aspects for blade/wing and its tubercles which have to be optimally set according to the selected airfoil and the specific operational flow regime. The spanwise length of perturbations, one of their geometrical aspects, is postulated to be of a great effect; however, it is little considered in research works. The objective of the present work is to investigate the effects of changing the tubercled length of the leading edge on the aerodynamic performance for highly cambered models at a low-Re transient flow regime which is considered to be the optimum design range for these highly applicable airfoils. An experimental approach was employed to test three models of the high lift S1223 airfoil with different waviness ratios (the waved length/total one) (20.83%, 50%, and 100% of the total span), and compare them with their smooth-leading edge counterpart. The tests were conducted in a subsonic wind tunnel at $text{Re}=100,000$ under an infinite-span (quasi-2D) basis over an attack-angle range from the zero-lift angle up to 30 degrees. The results revealed the great influence of the tubercled length on the aerodynamic performance as the fully modified model attained earlier stall but with highly soft characteristics while the least-tubercled one delayed the abrupt stall behavior of the baseline model by 22% without a penalty on the maximum lift coefficient.","PeriodicalId":339998,"journal":{"name":"2021 6th International Conference on Mechanical Engineering and Robotics Research (ICMERR)","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131523085","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, in general, the contact properties of multibody structures are not known with acceptable accuracy at the design stage, which makes the theoretical predictions of multibody structures quite unreliable. In theoretical or numerical studies, especially in automotive industry, contact surfaces are usually not modeled and some empirical values are frequently used to represent the dry friction properties. However, in most cases, the use of approximate, linear damping and stiffness values instead of the actual dry friction damping and contact stiffness of structures cannot yield results with acceptable accuracy in terms of vibration amplitude and natural frequency. Thus, accurate predictions of vibration properties of multibody structures require detailed theoretical models including not only the realistic representation of the elastic and inertia properties, but also accurate representation of the damping in the system. In this study, it is aimed to identify the contact properties of a specific bolted joint experimentally. For this purpose, a practical test procedure is selected among those available in the literature and an appropriate test rig is developed in order to identify the contact stiffness and dry friction damping properties of a bolted joint. U sing the measured data, the nonlinear elastic and damping properties of the contact are modelled as amplitude-dependent complex stiffness using the describing function method. The results show that, using the test rig developed, elastic properties of the nonlinear contact can be identified with acceptable accuracy. However, the accuracy of the identification of the damping properties of the contact is found to be somewhat low, hence the test rig and the associated data analyses used in this study can be improved further.","PeriodicalId":339998,"journal":{"name":"2021 6th International Conference on Mechanical Engineering and Robotics Research (ICMERR)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132842727","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, in such environments as nighttime and dark spaces, the visibility of the rover is degraded by the camera based method, and a new system for recognizing the traveling state is required. As a new method for recognizing the driving state, we focused on the intrinsic sensation of the human body and aimed to develop a system that recognizes the travelling state from the shape deformation of legs. In this study, we experimentally verified the relationship between the change in strain, which is the amount of deformation acting on the, and the traveling state when the wheel travels. From the experimental results, we confirmed that the strain in the leg was displaced and that the strain changed oscillatory when the wheel was traveling. In addition, based on the function of muscle spindles as mechanoreceptors, we discussed two methods of analyzing the strain change: nuclear chain fiber analysis and nuclear bag fiber analysis. From these analysis methods, we detected changes in the force applied to the wheels and the movement of the ground during traveling from the strain. Therefore, the change of the traveling state could be detected by the strain, and it was confirmed that the traveling state could be detected.","PeriodicalId":339998,"journal":{"name":"2021 6th International Conference on Mechanical Engineering and Robotics Research (ICMERR)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132355255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
