| Abstract: | Focusing on the problem of breaking of crankshaft in giant plunger slurry pump with flushing packing, the static strength and rigidity as well as fatigue strength of the crankshaft under the rational regime determined by optimizion are evaluated in this paper using the method of three dimensional finite element. The computation results agree with the reality proving the validity of the computation. The measures for preventing crankshaft from breaking is presented after analyzing the computation results. |
