Problems solved by technology

[0004] Since the test bench only separates the crankshaft and does not consider the influence of gas pressure and reciprocating inertial force in actual working conditions, the research on fatigue strength is inaccurate and has a large deviation from the actual situation. It does not meet the requirements of the actual internal combustion engine crankshaft Equivalent requirements for system operating conditions

Description

technical field [0001] The invention relates to the technical field of internal combustion engine power simulation systems, in particular to an expandable internal combustion engine crankshaft system simulation device. Background technique [0002] The crankshaft system is a key component of the internal combustion engine and a key factor affecting its life and work efficiency. To study the internal combustion engine crankshaft system, the existing relatively common methods are mainly: numerical simulation and experimental testing. The numerical simulation method is mainly based on numerical analysis software, inputting model parameters, setting boundary conditions, and solving related parameters; its main disadvantage is that the parameter setting of the simulation software is relatively ideal, and the influence of some environmental factors and material characteristic parameters is not considered, and the calculation results are consistent with the actual The situation ha...
