旋挖钻机动力头受力情况复杂,在施工过程中经常会出现动力头加压力不足,滑架滑板磨损快,角耳开裂等问题,严重影响施工质量和效率。根据理论力学、材料力学、弹塑性力学等理论知识,对加压钻进工况下旋挖钻机动力头进行受力分析并建立数学模型,同时进行有限元分析,为旋挖钻机动力头角耳结构优化设计提供理论依据。
Rotary drilling rig power head force situation is complex, in the construction process often appear lack of power head pressure, skateboard wear fast, cracked corners and other issues, seriously affecting the construction quality and efficiency. According to theoretical mechanics, material mechanics, elasto-plastic mechanics and other theoretical knowledge, the dynamic analysis of the rotary head drilling rig under pressure drilling conditions is carried out and the mathematical model is established. At the same time, the finite element analysis is carried out, Optimize the design to provide a theoretical basis.
