A Study on Engine Life Span Based on Engine Assembly Quality Analysis

摘要

In this paper, the main effective factors of engine assembly quality have been analyzed in detail. It provided a mathematical model of engine life span based on the laws of the changing of friction pairs gap and running-in analysis. On the basis of a EQ6100 engine test, the applied spectral analysis technique, it gained efficient technique measures to enhance the engine’s life span, and provided a proposal value and an allowed value of integrated position precision error.
