A APDL program is developed for analyzing the contact stress of journal bearing pair of roller cone bit. The 25 contact stress cases of different clearance fit(including clearance of large bearing is bigger, equal to and smaller than that of small bearing) journal bearing pair of the 8 1/2XXX roller cone bit are analyzed. The result is that the maximum contact stress is less when the clearance of large journal bearing pair is smaller than or equal to that of small journal bearing pair.

用参数化设计语言APDL编制了牙轮钻头滑动轴承的ANSYS接触有限元分析程序，根据钻头制造厂方提供的某8 1/2的轴承配合间隙尺寸，分三种不同的间隙配合（大轴间隙大于小轴间隙、大轴间隙等于小轴间隙、大轴间隙小于小轴间隙），共25种情况，对轴承的表面的接触应力进行了分析，得出：大轴间隙小于等于小轴间隙时最大应力比较小。

At driving bit mounted on the steering wheel airbag middle position, co-pilot-bit airbag installed in front of the platform itself, the accident happened at the moment can effectively protect the driver and co-occupant spaces of the head and chest, because facing fierce collision will happen cause the vehicle in front of large deformation, and the vehicle occupant as the inertia of this heavy dive forward, causing the car with each other percussive elements, while driving the location of the car airbag can effectively to prevent the steering wheel when the collision happened at the top of the chest to the motorists to avoid the fatal injuries.

在正驾驶位的气囊装在方向盘的中间位置，副驾驶位的安全气囊安装在正前方的平台内部，在意外发生的瞬间可以有效的保护驾驶员和副驾驶位乘员的头部和胸部，因为正面发生的猛烈碰撞会导致车辆前方大幅度的变形，而车内乘员会随着这股猛烈的惯性向前俯冲，造成跟车内构件的相互撞击，另外车内正驾驶位置的安全气囊可以有效的防止在发生碰撞时方向盘顶到驾驶者的胸部，避免致命的伤害。
