根据矿用防爆胶轮车井下巷道作业时恶劣工作环境的特点,在ADAMS软件中建立胶轮车的多体动力学模型,并针对左右颠簸路面进行动态仿真分析,获得随机激励下的峰值力。在ANSYS软件中建立车体的有限元模型,用有限元法对车架进行动态应力分析,得到了各部位的应力分布情况。通过分析可知,最大应力为305 MPa,满足强度要求。其中机架与销轴铰接板的连接处、上下销轴的表面都出现了应力集中的现象,其他位置受力较小,可以对车架的结构进行优化改进。
According to the characteristics of the harsh working environment when mine roadway working in mine rubber explosion-proof rubber tire, ADAMS software to build multi-body dynamics model of rubber tire vehicle, and for the bumpy road surface dynamic simulation analysis to obtain the peak force under random excitation. The finite element model of the car body is established in the ANSYS software. The dynamic stress analysis of the car frame is carried out by the finite element method. The stress distribution of each part is obtained. According to the analysis, the maximum stress is 305 MPa, which meets the strength requirement. One rack and pin hinge plate connection, the upper and lower pins have a surface stress concentration phenomenon, the other positions less stress, you can optimize the structure of the frame.
