摘要:A piston is an important part of an engine. Its shape is designed into middle-convex and varying ellipse (MCVE) to adapt to the complex working environment. The main requirements of MCVE piston machining are high frequency response, small range tool motion, and high precision. ...

摘要:Abstract(#br)The piston secondary motion is the most predominant excitation source for the mechanical vibration of diesel engine, which is directly affected by the piston profile. The effects of piston skirt profile on the dynamic behavior of piston and the vibration characteris...

摘要:Abstract(#br)Piston secondary motion caused by the changes in side forces and a clearance between piston skirt and cylinder liner, is inevitable in crank train. Studies reporting the combined effect of the associated joint clearances on piston secondary motion are rare, due to th...

摘要:Abstract(#br)Liquid displacement by a pressure-driven piston is a common phenomenon encountered in different industries. The main challenge of the displacement process is its inherent fast transient nature. The objective of the current work is to study such a process experimental...

摘要:Abstract(#br)The fluctuation of gas exchange is easy to induce the free piston linear engine (FPLE) to run unsteadily, because the gas exchange, piston motion and combustion of FPLE are intimately coupled with each other. This work presents a simulation to investigate the effect ...

摘要:Abstract(#br)Volumetric losses are essential to ensure proper lubrication of moving components in an axial piston pump (APP). However, amplification of these volumetric losses can be observed when one or more pistons of the APP degrade due to friction and contaminated fluid. This...
