Abstract The T-shaped groove surface with groove width of 0.3 to 1.2 mm and groove depth of 0.6 to 1.5 mm is prepared on the copper surface by using electric spark wire cutting technology, Set up a set of wall temperature measurement, bubble visualization and steady flow heating test bench. Experimental observations of boiling heat transfer of deionized water on different heat transfer surfaces are achieved. The boiling curves of T-shaped surface such as superheat, heat flux and heat transfer co...

The T-shaped groove and the square-column microstructure of the aluminum alloy surface were constructed by EDM. It was found that the contact angle of the square column formed by the two processes can reach 147.62°, and the surface of the part exhibits high viscosity at the same time. Successfully achieved the preparation of highly viscous hydrophobic surfaces. At the same time, solutions of different PH were prepared to further characterize the chemical stability of the samples. It is found tha...

In this study, a more conveniently method was tried to prepare T-shaped groove structure surface with HS-WEDM method on the surface of an aluminum alloy, and the results shown that processed surface has super-hydrophobic and high- adhesion properties. The fabricated surface morphology was observed by scanning electron microscopy and laser confocal and it was found that there are some micrometers or submicron-scale pits and mastoids distributed on the surface of the sample with sub-millimeter T-s...

As the demand for high speed and light weight of automobiles continues to increase, the requirements for power, volume and weight of the engine are also increasing. In the design and development of automobile engine cylinder head, the finite element analysis of its structural strength, stiffness and finite element model is used to analyze the static strength and finite element modal analysis of the cylinder head. The natural frequency and mode state of the cylinder head structure under the free ...

Based on the background of engine lightweight and low noise, this paper used the 3D modeling software Pro/E to build the mathematical model of a high speed engine. The finite element mesh was divided by ICEM. The structural vibration of the engine complete machine was calculated by combining finite element theory with multi-body dynamics. By using the Timing Drive and Power Unit in AVL Excite, the multi-input parameter’s coupled calculation of the gas distribution mechanism and crankshaft connec...

At the beginning of the design of a certain type of engine, the dynamic analysis of the left and right valve chamber assembly of the engine is carried out by means of finite element method, and the modal calculation is carried out. The overall stiffness of the cover of the left and right valve chamber is evaluated. The modal frequency and mode of the hood cover are obtained. According to the calculation results, the scheme of the valve chamber cover is optimized. The modal analysis is carried ou...

Automotive air conditioning compressor bracket connects the compressor and engine, and make its long-term vibration in the bad environment, which will cause the compressor can't work smoothly, safely and reliably, therefore the design rationality of automotive air conditioning compressor bracket, directly affects the performance of air conditioning, in turn, affects the vehicle harshness (NVH) performance. So analyze the vibration performance of air conditioner compressor in the design phase is ...
