摘要
管状带式输送机托辊布置不合理会影响整机运行可靠性,导致输送带受力不均,增加跑偏和扭转风险,进而影响生产效率,增加维护成本和停机时间。文中运用有限元仿真方法对4种托辊布置方式进行建模,模拟15个工况,深入剖析不同因素对管状带式输送机阻力的影响规律。研究表明:采用尖点型布置方案时,不同张力下会使阻力提高2%~7%;在相同间距下,输送带的张力越大阻力越小;而不同托辊间距对低张力区阻力变化影响为6.1%,对高张力区阻力变化影响仅1.6%。研究成果为不同工况下托辊布置优化提供依据,可有效降低运行阻力、减少输送带磨损并提升设备稳定性,对工程实践中管状带式输送机系统的可靠性提升具有重要意义。
Unreasonable roller layout of pipe conveyors compromises overall reliability,induces non-uniform belt stress,and increases the risks of deviation and torsion,thereby reducing production efficiency and raising maintenance costs and downtime.Four roller-layout plans were modeled by finite element simulation,simulation were carried out under fifteen operating conditions,and the influence of different factors on the running resistance of a pipe conveyor was analyzed.The results reveal that adopting the cusp layout increases resistance by 2%-7%under varying belt tensions.Under the same roller spacing,higher belt tension produces lower resistance.The effect of different roller spacings on resistance change is 6.1%in the low-tension zone but only 1.6%in the high-tension zone.These findings provide a basis for optimizing roller layout under different operating conditions,effectively reducing running resistance and belt wear and improving equipment stability,which is significant for enhancing the reliability of pipe conveyor systems in engineering practice.
