摘　　要：D_(38)型钳夹车的端盖及其连接螺栓的强度直接影响D_(38)型钳夹车的使用安全。本文根据这种夹车在运输货物的实际受力情况,科学地选择应力的静态与动态点,测出应力值,对该车的端盖与其连接螺栓的强度进行了检算,并将计算结果和实际运输的有关试验数据进行对比分析。结果表明:目前使用的端盖和连接螺栓的最大动应力都小于设计的允许应力,端盖和连接螺栓的强度有充分的保证。研究工作为端盖运输方式的试验研究提供了理论参考,并为确保特种货物运输安全奠定了基础。Strengths of the end shield and its fixed bolt of D38 schnabel car affect the car’s utility and safety. According to the loading situation of the car in transportation, authors scientifically selected the stress survey points — the static points and dynamic stress points, and obtained the stress data. Then, the theory strengths of the end shield and the fixed bolts are calculated with dynamic numerical simulation method. Comparison shows that all the calculation values of the stresses are within the allowable stresses. it is proved that the end shield and the fixed bolt are safe. The research work has provided theoretical reference for studying experiments of end shield transport of large car.
