introduction:The location of the gate has a direct effect on the quality of the plastic,When determining the location of the gate,The following points should be considered:When the melt flows in the cavity,The kinetic energy loss is minimal,To do this must be made A flow(Inclusive shunt)Be the shortest; BEach stream reaches its farthest point at roughly the same time; CFeed from the thicker part of the wall first; DConsider the diversion of each strand as small as possible;Effectively expel the gas from the cavity.If there is a core with forming holes in the cavity,The gate should avoid impacting the small core,And the pressure loss of the melt should be taken into account.If the cavity has metal inserts,Gate should be kept away

introduction:A device in a gas turbine that burns the injected fuel with high-pressure air from a compressor to form high-temperature gas。It releases energy from the fuel at almost constant pressure,Direct heating of the working medium(air)To improve their ability to do work。usual,It is made of steel plates and superalloy sheets。 Characteristics of the combustion process in order to adapt to the gas turbine light and small equal points,The size of the combustion chamber is designed to be relatively compact,In general, it can burn and release larger than atmospheric boilers per unit time and per unit volume 10~300Double heat,Thus the combustion process is at high thermal intensity

introduction: Control the level of detail the surface displays,When the coloring model is dynamically oriented,It can reduce the computation of the system。The result is that the model motion appears smoother,The synchronicity of the driving forces is better。The level of detail used in the model (LOD) The efficiency depends on the configuration of the system。 Control system performance: Click“view”(View)>“Display setting”(Display Settings)>“property”(Performance)。“property”(Performance) Dialog box opens。

introduction:Abnormal combustion in gasoline engines。When the gasoline engine burns normally,The spark plug is prepared after a short ignition delay period,A flame core is formed near the electrode gap,Flame from the flame core to30~40meter/The velocity of the second propagates to the surrounding area of unburned mixed gas,Make the mixture in the combustion chamber burn in a sequential manner,To the end(See picture[Gasoline engine combustion diagram])。It was found in the study of gasoline engine knock by high-speed photography,In the process of flame propagation in the combustion chamber of gasoline engine,Unburned mixture away from spark plug(Terminal mixture),Compressed by the expansion of the burned mixture,The local temperature here is due to thermal radiation

introduction:Most of the self-aligning roller bearings[bearing:bearing(“Bearing”,Japanese person“Axial receptor”)It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said,When other parts move relative to each other on the shaft,A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]There are many causes of damage,Such as a load that exceeds the original estimate、Ineffective seal、Too small bearing clearance caused by too tight fit and so on。Each of these factors has its own special damage pattern and will leave special damage traces。therefore,View damaged shaft
