摘　　要：无轨胶轮车在进行井下煤炭输送的过程中,受到地面状态的影响对车架的强度具有较高的要求。采用有限元仿真的形式对弯曲扭转载荷作用下车架应力应变进行分析。结果表明,胶轮车的车架应力应变主要发生在后车架靠近悬空的位置处,应力及应变的大小满足系统的要求。In the process of underground coal conveying,trackless rubber wheelbarrow has high requirements on the strength of the frame due to the influence of the ground condition.Finite element simulation is used to analyse the stress and strain of the frame under bending and torsion loads,and the results show that the stress and strain of the frame of the rubber-wheeled vehicle mainly occurs in the rear frame near the overhanging position,and the magnitude of the stress and strain meets the requirements of the system.
