摘　　要：为评估无依托发射场坪的强度稳定性,需要对导弹发射车的对地荷载做详尽分析,找出最大应力工况。文中分析了导弹发射过程中的各种工况,并进行了力学计算,通过对比,判断出发射车对地最大载荷状态,以此作为场坪强度评估的理论依据。同时,通过构建支腿对地载荷检测系统,实测了支腿对地压力,通过对比分析,验证了计算方法的合理性。研究结果可以为导弹采用无依托发射时的场坪选取和强度判断提供参考。In order to judge the strength stability of the unsupported random launching site, detailed analysis of the load exerted on the ground by the launching vehicle need to be carried out, and find out the biggest stress operating mode. In this paper, the different operating modes are analyzed during the process of missile launching, and the detailed mechan- ical computation is performed. Through comparison analysis, the biggest load situation is judged. Meanwhile, the load ex- erted on the ground by the hydraulic legs is measured by the constructed load detecting system, and the rationality of the computation method is proved. The research conclusions can offer references for selecting and judging intensity of missile launching site when unsupported random launching way is applied.
