Firstly, by analyzing the unbalance of the arrangement caused by the deviation of the mass moment of the blade, and considering the concentricity of the disk, an optimization model of the unbalanced amount of the blade assembly was established. Secondly, the selection operator, crossover operator, and mutation operator of the algorithm were designed, and the cloud adaptive genetic algorithm was used to optimize the assembly unbalance. Thirdly, the mass moments of a group of aero-engine blades were weighed using a moment scale (MW0), and the blade mass moment distribution and assembly unbalance under the six blade arrangements were analyzed. Finally, by setting different disk concentricity, the corresponding blade arrangement and the final rotor unbalance were obtained. Through analysis, it was found that the unbalance of GA is at least 57.5% optimized relative to the weight sorted, sorting type 2, sorting type 4, and sorting-1\/4 skip method, and the unbalance optimized by the CAGA is 95.7% optimized relative to GA. In the case of different initial concentricity of the disk, the effective algorithm accuracy is still maintained, which proves the effectiveness of the method for the arrangement of asymmetric rotor blades. This method establishes an effective asymmetric rotor blade arrangement model, uses the cloud adaptive genetic algorithm to sort the blade assembly, and effectively reduces the unbalanced amount of the asymmetric rotor.<\/jats:p>","DOI":"10.3390\/sym13050832","type":"journal-article","created":{"date-parts":[[2021,5,10]],"date-time":"2021-05-10T02:54:58Z","timestamp":1620615298000},"page":"832","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Blade Sorting Method for Unbalance Minimization of an Aeroengine Concentric Rotor"],"prefix":"10.3390","volume":"13","author":[{"given":"Chuanzhi","family":"Sun","sequence":"first","affiliation":[{"name":"Center of Ultra-Precision Optoelectronic Instrument Engineering, Harbin Institute of Technology, Harbin 150080, China"},{"name":"Key Lab of Ultra-Precision Intelligent Instrumentation Engineering, Harbin Institute of Technology, Ministry of Industry and Information Technology, Harbin 150080, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pinghuan","family":"Xiao","sequence":"additional","affiliation":[{"name":"Center of Ultra-Precision Optoelectronic Instrument Engineering, Harbin Institute of Technology, Harbin 150080, China"},{"name":"Key Lab of Ultra-Precision Intelligent Instrumentation Engineering, Harbin Institute of Technology, Ministry of Industry and Information Technology, Harbin 150080, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaoming","family":"Wang","sequence":"additional","affiliation":[{"name":"Center of Ultra-Precision Optoelectronic Instrument Engineering, Harbin Institute of Technology, Harbin 150080, China"},{"name":"Key Lab of Ultra-Precision Intelligent Instrumentation Engineering, Harbin Institute of Technology, Ministry of Industry and Information Technology, Harbin 150080, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yongmeng","family":"Liu","sequence":"additional","affiliation":[{"name":"Center of Ultra-Precision Optoelectronic Instrument Engineering, Harbin Institute of Technology, Harbin 150080, China"},{"name":"Key Lab of Ultra-Precision Intelligent Instrumentation Engineering, Harbin Institute of Technology, Ministry of Industry and Information Technology, Harbin 150080, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,5,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"259","DOI":"10.5194\/ms-9-259-2018","article-title":"Location of unbalance mass and supporting bearing for different type of balance shaft module","volume":"9","author":"Kim","year":"2018","journal-title":"Mech.
