以某铰接式无轨胶轮车的铰接部位为研究对象,针对其不同的使用工况,分析了摆动式铰接架和圆锥滚子轴承的受力状态,并利用有限元方法对铰接架进行了应力分析,用以评价铰接架的结构强度,最后对圆锥滚子轴承进行了加权和系统寿命计算,校核轴承寿命对系统性能的影响,从而为结构改进设计提供了理论依据,对评价整机可靠性能具有一定的指导意义。
Taking the articulated parts of a trolley-mounted rubber-free track rubber vehicle as the research object, according to the different working conditions, the stress state of the swing articulated frame and the tapered roller bearing is analyzed and the hinge frame is stressed by the finite element method Analysis, to evaluate the structural strength of the hinge frame, and finally the tapered roller bearing weighted and system life calculation, check the bearing life on the system performance, thus providing a theoretical basis for the structural improvement of the design, Performance has a certain guiding significance.
