For accurate modeling and optimization of the air-powered engine, basic model engine’s working process was established at first. Experiments on a prototype modified from an internal combustion engine were carried out to verify feasibility model’s validity. Based experimental results, balanced valve designed. Afterward, virtual with newly designed system built relative simulations conducted analyze dynamic performances engine. Results show that controlling is easy achieve parameterization....
In recent years, Hybrid Cellular Automata Method (HCAM) has been successfully applied to solve structural topology optimization problems. However, there was no report on HCAM research of three-dimensional composite structure composed multiple materials and bodies. Therefore, in this paper, non-cube cells irregular size (such as tetrahedral with adaptive changes inside length) Finite Element (FEM) are introduced extend HCAM, which is better more flexibly fit complex geometric shapes....
Owing to the micro-electro-mechanical system technology, thin-film thermocouple (TFTC) arrays have emerged for real-time temperature mapping. A minimum distance of 2 mm between junctions and a junction size up 9 μm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> been achieved previously. In this study, self-calibration TFTC array with 24 TFTCs 16 platinum resistance thermometers (PRTs) on 22 diameter disk is designed based...
In the detection of acoustic emission signals due to compressed air leakage, various complicated factors make it difficult position leakage sources. Specially, although ultrasonic are wanted in detection, reflected ones belong interfering factors. this research, with an leak scanner, predefined experiments were implemented find different characters between and direct waves by measuring analyzing spectrums from artificial leak. And a calculation method for numerical value express these is...
Pressure reducing devices are the essential and critical components of a pneumatic system. But energy lose due to pressure process is considerably huge when there high difference.
