A dynamic simulation of the cutting process was used to analyze the variation of the load. Based on the dynamic analysis of the coal and rock that were cut by the spiral drum, the stress cloud diagram of the coupled model of the spiral drum and the coal and the plastic domain evolution law of the coal and the rock were obtained from the coal to the rock. The time history curves of the parameters, such as the stress and strain of the drum and the pick, were obtained, and the stress distribution of the spiral drum during the working process was ascertained. The results showed that when the spiral drum cuts the interface between the coal and the rock, the coal and the rock collapsed and the working load fluctuated. Changing the traction speed in order to change the rotational speed of the drum had a more obvious effect on the load and the stress on the drum. Through the use of simulation, the stress distribution cloud diagram of the drum was obtained. The study has shown that the stress on the end plate was significantly higher than that on the cutting blade. The maximum stress acting on the alloy head was 1209.26\u2009MPa. This study has provided a basis for the design and optimization of the drum with regard to reliability.<\/jats:p>","DOI":"10.1155\/2019\/1482051","type":"journal-article","created":{"date-parts":[[2019,1,3]],"date-time":"2019-01-03T23:30:43Z","timestamp":1546558243000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["A Study on the Dynamic Transmission Law of Spiral Drum Cutting Coal Rock Based on ANSYS\/LS\u2010DYNA Simulation"],"prefix":"10.1155","volume":"2019","author":[{"given":"Lijuan","family":"Zhao","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9396-5124","authenticated-orcid":false,"given":"Hongmei","family":"Liu","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7756-1418","authenticated-orcid":false,"given":"Wenchao","family":"Zhou","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2019,1,3]]},"reference":[{"key":"e_1_2_9_1_2","first-page":"5","article-title":"Simulation analysis on strength of cutting picks with various shapes based on LS-DYNA","volume":"39","author":"An Y.","year":"2011","journal-title":"Coal Mine Machinery"},{"key":"e_1_2_9_2_2","first-page":"97","article-title":"Numerical simulation of the process of spiral drum cutting coal in thin coal seam","volume":"45","author":"He J.","year":"2013","journal-title":"Coal Engineering"},{"key":"e_1_2_9_3_2","volume-title":"Study on Numerical Simulation of the Spiral Drum Cutting Coal Rock","author":"Dong R.","year":"2012"},{"key":"e_1_2_9_4_2","first-page":"584","article-title":"Analysis and optimization for pick line distance of shearer roller","volume":"5","author":"Lu H.","year":"2013","journal-title":"Journal of Taiyuan University of Technology"},{"key":"e_1_2_9_5_2","first-page":"171","article-title":"Research on the strength of the cutting teeth of the excavator based on ls-dyna under different hardness of coal","volume":"12","author":"Wu T.","year":"2013","journal-title":"Mechanical Engineer"},{"key":"e_1_2_9_6_2","first-page":"81","article-title":"Analysis of shearer drum motion parameters based on LS-DYNA","volume":"6","author":"Xue J.","year":"2014","journal-title":"Coal Mine Machinery"},{"key":"e_1_2_9_7_2","volume-title":"Research on Dynamic Characteristics of Drum Shearer Cutting Unit","author":"Guo H.","year":"2014"},{"key":"e_1_2_9_8_2","volume-title":"Structural Parameters Optimization for Cutting Drum of Coal Cutting Machine","author":"Wu Q.","year":"2015"},{"key":"e_1_2_9_9_2","first-page":"1","article-title":"Numerical simulation of cutting coal of shearer drum based on ANSYSLS-DYNA","volume":"36","author":"Song Z.","year":"2016","journal-title":"Shanxi Coal"},{"key":"e_1_2_9_10_2","first-page":"128","article-title":"Research on the cutting performance of ladder drum","volume":"49","author":"Zhou F.","year":"2017","journal-title":"Coal Engineering"},{"key":"e_1_2_9_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tust.2004.08.010"},{"key":"e_1_2_9_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tust.2010.08.005"},{"key":"e_1_2_9_13_2","doi-asserted-by":"publisher","DOI":"10.1108\/13552511211226210"},{"key":"e_1_2_9_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tust.2012.11.009"},{"key":"e_1_2_9_15_2","doi-asserted-by":"publisher","DOI":"10.1115\/1.4026326"},{"key":"e_1_2_9_16_2","doi-asserted-by":"publisher","DOI":"10.1515\/amsc-2016-0027"},{"key":"e_1_2_9_17_2","first-page":"41","article-title":"Simulation and analysis for helical drum cutting coal rock by LS-DYNA","volume":"34","author":"Li W.
