The Numerical Analytic Method (NAM) and the Discrete Vortices Method (DVM) are developed for simulating the flow around an airfoil when it is in the close proximity to the ground. The author proposes the NAM for modeling the flow around the airfoil near the ground and analyzes two approaches to solving the problem of Wing-in- Ground (WIG). The first method is based on the simulation of the ground surface, while the second one uses the reflection method. It has been shown that the increasing in the relative airfoil thickness reduces the positive WIG lift effect. It is also established that there is an optimal airfoil angle of attack at which the maximum lift occurs near the ground.","PeriodicalId":356055,"journal":{"name":"2017 International Conference on Mechanical, System and Control Engineering (ICMSC)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132066050","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}

And the values of their fractal dimension can be used as an measurement to classify and recognize the mechanical parts. In addition, the values can guide robots to grab parts. However, the image obtained by a vision system, which contains part images main image and image background will affect the calculation of fractal dimension of main images. In order to solve the problem, an improved differential box-counting method is designed in this paper. The fractal dimension of part images which has been cut and rotated can be calculated using this differential box- counting method. The experimental result shows that the improved differential box-counting method can calculate the fractal dimension of different size-length images, and the values are more stable. The improved method solves the problem that traditional algorithm can only calculate the fractal dimension of image which side length is integer power of 2.","PeriodicalId":356055,"journal":{"name":"2017 International Conference on Mechanical, System and Control Engineering (ICMSC)","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115429838","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}

The efficiency of a pulse tube has been proposed, which can be used to describe the loss of pulse tube quantitatively. The resulting phase angle shift between gas velocity and pressure is obtained analytically with account of friction in oscillating flow in a tube.

Therefore, it is greatly significant to research the vibration attenuation technology for the wind tunnel air-supply pressure pipeline. In allusion to the fluid-structure interaction vibration problem of pressure pipeline system, the vibration spectrum is measured through time-domain signal to test the vibration performance of certain pipeline under different working condition parameters and research the pipeline vibration attenuation technology. Specifically, passive control technology and numerical simulation method are adopted to research the correlation between vibration amplitude, vibration velocity and spring stiffness, damping under pressure pulsation excitation. Afterwards, suitable elastic damper, viscous damper and installation position are selected according to numerical simulation result. Finally, the experimental verification result shows: it is safe and reliable to firstly predict the vibration performance of the pressure pipeline system with complex spatial arrangement through numerical simulation method and then perform the vibration attenuation design; the maximum vibration amplitude of the improved pressure pipeline system can be maximally reduced by 62.26%, which fully satisfies the expectation.","PeriodicalId":356055,"journal":{"name":"2017 International Conference on Mechanical, System and Control Engineering (ICMSC)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125299047","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}
