Modeling Loads on Diesel Engine Timing Gear Components in CAD Systems for Analyzing the Causes of Accidental Failure

Key Points

This research aims to analyze the loads on timing gear components in diesel engines and their failure causes.
Investigated loads on timing mechanism parts due to shock interference.
Used CAD systems (COMPASS 3D and Altair Inspire) for modeling and analysis.
Determined stress and strain values for rocker arms and valves.
Identified stress and strain values under emergency conditions.
Established insights into the causes of timing mechanism failures.
Provided materials that can enhance design and operability analysis.

Abstract

The loads acting on the parts of the gas distribution mechanism (timing) of a diesel engine under conditions of shock interference when the valve plate is subjected to an impact from the bottom of the piston have been investigated. This emergency mode occurs when the normal kinematic connection between the crankshaft and the gas distribution mechanism is broken due to a broken belt or other causes. Based on modeling in the CAD systems (COMPASS 3D and Altair Inspire), the stress and strain values for rocker arms and valves were determined. These work materials can be used in the design, operability analysis, and search for causes of gas distribution mechanism failure in internal combustion engines (ICE).
