摘　　要：通过对W型曳引抽油机,主要构件的受力分析,为合理设计构件提供有关强度、刚度和稳定性分析的理论依据和方法。针对不同用途的构件,正确选择材料,有的构件应具有足够的强度,以保证在规定的使用条件下不发生破坏;有的构件应具备足够的刚度,以保证在规定的使用条件下不产生过分的变形;有的构件应具备足够的稳定性,以保证在规定的使用条件下不产生失稳现象。同时,还要考虑到安全和重量的关系,安全与经济的关系,合理的选用材料。Based on the force analysis of the main components of W type tractive pumping unit,the strength,rigidity and stability of W type tractive pumping unit were designed reasonably.For the different components,some components should have sufficient strength to prevent failure under normal working conditions,some components should have sufficient stiffness to avoid deformation under normal working conditions,some components should have sufficient stability,in case they occur instability under normal working conditions.At the same time,the relations of safety & weight,and safety & economy should be taken into account,then reasonably select material.
