摘要:
卸胎机夹取的巨型轮胎质量可达6 t，存在较大的惯性力，在工作过程中会因为碰撞及运动引起系统强烈振动，容易造成轴承等零件失效。 文章基于ADAMS 动力学仿真方法对卸胎机动态特性展开研究。 研究表明，导轨轮轴与定环回转约束部位在卸胎机夹紧轮胎的过程中因夹板与轮胎发生碰撞，产生较大的冲击载荷，导轨轮轴固定部位合力最大可达260 kN，定环回转约束部位反力约为设备自重。 摇臂轴轴承与定环连接的螺栓固定部位在工作过程中支反力变化趋于一致，在翻转过程中，二者合力保分别可达40 、75 kN，且存在较大冲击。 研究结果可为轴承选型、螺栓校核及定环结构的强度刚度提供载荷边界，同时为卸胎机结构的动态优化设计提供技术支撑。
Abstract:
The mass of the giant tire clamped by the tire unloader can reach 6t, and there is a large inertial force. During the work process, the system will be strongly vibrated due to collision and motion, which will easily cause the failure of bearings and other parts. For this reason, ADAMS dynamic simulation method is used to study the dynamic characteristics of the tire unloader. The research shows that the guide wheel axle and the fixed ring rotation restraint part collide with the tire during the tire unloading process, resulting in a large impact load. The combined force of the fixed part of the guide wheel shaft can reach about 260kN, and in the fixed ring rotation restrained part, the reaction force is about the weight of the equipment. The change in support force of the bolt-fixed part connected to the rocker shaft bearing and the fixed ring tends to be consistent during the working process. During the turning process, the combined force of the two can reach 40kN and 75kN, respectively, and there is a large impact. The research results can provide load boundaries for bearing selection, bolt calibration, and strength and stiffness of the fixed ring structure, and provide technical support for the dynamic optimization design of the tire unloader structure.
