关于矿用无轨胶轮车车架受力分析及优化的研究

Research on Stress Analysis and Optimization of Mine Trackless Rubber Wheel Frame

利用Solidworks软件绘制车架模型,分析了无轨胶轮车在拐弯和路面不平整工况下车架的受力状态。结果发现:当由于里面不平导致左后车轮不受力时,车架位移变形和受力情况最为严重,最大位移值和应力值分别达到了9.762 mm和219.5 MPa。提出将后车架纵梁厚度增加8mm的优化方案,在相同工况条件下对应的最大位移值和应力值分别降低到了4.326 mm和168.3 MPa,优化效果显著。

Based on the ABAQUS software, the stress state of the frame of the trackless rubber wheel vehicle during cornering and uneven road conditions is established. It was found that when the rear wheels are not stressed, the displacement and stress of the frame are the most serious. The maximum displacement and stress values reach 9.762 mm and 219.5 MPa, respectively. An optimization scheme was proposed to increase the thickness of the rear frame longitudinal beam by 8 mm. Under the same working conditions, the corresponding maximum displacement and stress values were reduced to 4.326 mm and 168.3 MPa respectively, and the optimization effect was significant. The application of optimization measures to engineering practice has achieved good application results and significantly improved the service life of the frame.
