摘要:
割刀常因振动而折断刀片，造成切割设备失效，影响施工安全。为降低ND-J114型号机械式内割刀的事故率提高割刀使用寿命，采用多体动力学的方法，利用ADAMS软件对其切削套管的过程进行动态模拟，在不同钻压和转速情况下，对割刀切削力和角加速度的变化规律进行分析，从割刀振动的角度出发，通过降低割刀的振动来降低刀片折断的风险。分析结果表明：割刀在切削套管的过程中最优钻压为4 800 N，割刀运转平稳；切削力的大小跟钻压近似于成正比关系；割刀最优转速为29 r/min，割刀运转平稳；切割转速在10~30 r/min时，切割效果较好，切割设备越不易折断；转速对切削力大小的影响较小。
Abstract:
The blade of cutter often break off due to the vibration, which causes the failure of cutting equipment and influence the construction safety. To reduce the accident rate of ND-J114 type mechanical internal cutter and improve its service life, the dynamic simulation on the process of casing cutting by this cutter was carried out by using ADAMS software with the method of multi-body dynamics. The change laws of cutting force and angular acceleration of the cutter under different bit pressure and rotation speed were analyzed, and starting from the perspective of cutter vibration, the risk of breaking off of the blade could be reduced through reducing the vibration of cutter. The results showed that the optimal bit pressure of the cutter in the process of casing cutting was 4800 N, and the cutter operated smoothly. The cutting force was directly proportional to the bit pressure approximately. The optimal rotation speed of the cutter was 29 r/min, and the cutter operated smoothly. The cutting effect was better when the rotation speed was between 10 r/min and 30 r/min, and the cutting equipment was not easy to break off. The rotation speed had little effect on the cutting force.
