Abstract

The flexible crankshaft may influence diesel’s instantaneous speed when diesel runs at high speed and load. In this paper the nine-degree crankshaft dynamic model is set up aim at 6-135 type diesels, and studies the instantaneous speed fluctuating rules at different position of crankshaft. The Simulating outcome shows that the obvious difference and rules are exist in instantaneous speed of all degrees: The instantaneous speed waveform corresponding to each cylinder accomplishes a change of several small wave crests to one beg crest gradually from freedom end to flywheel end. At last the simulating outcome are compared to experimental measured instantaneous speed of freedom end and flywheel end, they are in agreement at both wave shape and frequency spectrum sides, then the model’s effect is proved.
