不同工作条件下掘进机截割臂的强度分析

Analysis of Strength Effect Fact for Cutting Arm

截割臂在掘进机工作时承受很大的力和弯矩,它的强度是否满足,关系到整台机器设计的成败,有必要对其进行认真的强度分析。截割臂的受力比较复杂,各个影响因素在不同的工作条件下对其强度的作用需要细致的分析,才能确定其带来的实质性影响。

Cutting arm will undertake great power when the tunnel is working.the arm must be strong enough,and it is very important for the success of the design,the strength should be analysed.Making an analysis of the strength.The load of cutting arm is quite complicated.Each element that affects the strength under different working conditions to be analyzed in details so that the substantial effects brought by them can be decided.
