Research on Optimal Design and Calculation of Silicone Oil Damper For Diesel Engines
Aiming at the problem of frequent destruction of crankshaft bolts of a certain type of diesel engine due to excessive amplitude of torsional vibration.We performed vibration characterization on the engine crank-shaft equivalent system model and optimized the design of the silicone oil damper.The proposed optimization scheme has less modification to the damper,effectively improves the pass rate of the damper bench test,and sig-nificantly shortens the product development cycle.We also conducted crankshaft torsional vibration reliability tests on the optimized scheme,and the test results show that:on the basis of the original machine,the selection of a small damper,and reduce the width of the inertia block of the original damper by 7mm,which can improve the 4th harmonic amplitude,and ensure that the 8th harmonic amplitude does not exceed 0.15 deg.
