Twisted and coiled polymer actuators (TCAs) are a kind of efficient artificial muscles, which have good prospects for application in soft robots, bionic devices, biological, medical, other high-tech fields. However, the inability to dynamically sense adjust strain actuator will lead uncertainty accuracy deformation strain, resulting imprecise target action. Herein, TCAs with self-sensing ability (TCASA) prepared by integrating stretchable optomechanical film (SOMF) sensors into TCAs,...
Abstract The segmentation of wear debris images is a prerequisite for ferrographic analysis, and uncertainties errors in will inevitably affect the subsequent analysis. In this work, small-data semantic model constructed based on HRNetv2 ferrography acquired by using an online visual ferrography. A major advantage current that fewer are required training, iterations needed. work performed with both clean oil contaminated oil, good results can be found. Specially, experimental show achieve...
To solve the problems of monitoring wear debris in black oil, a direct reflection online visual ferrograph (OLVF) detector is presented. In current OLVF detectors, reflected light source used. The emitted by directly instead passing through lube oil. Therefore, transparency oil ceases to matter. Two experiments were conducted validate imaging feasibility and effectiveness newly developed detector. results show that feature information can be reliably obtained from this detector, it also used...
For improving the detection accuracy of wear debris visual information for online monitoring, a full field-of-view Online Visual Ferrograph (OLVF) detector is presented. In current OLVF detector, semi-transparent optical diffusion film clamped into gap between bottom quartz window and two magnetic poles as background microscopic imaging, by which emitted light circular ring LED array diffusely reflected. A reflected imaging system developed to form OLVF, mathematical relationship its depth...
Abstract Due to the influence of thermal stress and other factors during laser cladding, cracks will appear in cladding layer. To reduce loss, an effective method is detect early adjust fusion parameters promptly. The paper utilized acoustic signal detection technology collect crack defect signals process. Subsequently, collected were subjected time-frequency analysis wavelet thresholding denoising. Then by applying a custom approach for each level coefficients, denoised. results showed that...

The preparation of nano-modified concrete and its application in road pavement materials have broad prospects for improving the wear resistance surfaces reducing engineering costs. This article mainly studies cost-effectiveness nano-materials applied engineering. uses ABC classification method to analyze project cost. First, it analyzes impact each factor cost on cost, finds corresponding A, B, C factors, so as focus management A factors. Then A-type factors find influencing take reasonable...
Automatic open-parachute-device is an essential device in the field of aviation life-saving technology. In this paper, on basic mechanism, structure its reliability function given. According to indicators, considering main failure mode and combining with similar products' statistical data, analysis design indicators are processed. Successively according principle "redistribution method" "proportional distribution about rate, calculated detail. The results showed that allocation little...
Abstract One system of borophosphosilicate (BPS) glass-ceramics has been synthesized by sol-gel process and solid-mixed below 950°C in air. Through XRD SEM analysis, the similarities differences BPS derived two methods structures crystallizing was studied too. It is substantiated that SiO2 glass phase wraps up BPO4 crystalline grains. Between 400°C 900°C, liquefaction crystallization concur at same time to keep chip shape. The typical dielectric properties sintered show possess constant less...
In video image sequences, assume that face forms larger interference in athletic process and use traditional algorithm to extract facial features which may lead target pixel blending feature missing problems. Three-dimensional reconstruction has poor authenticity characteristic distortion. order solve this problem, paper proposes an anti-interference three-dimensional motion extraction method based on multiple constraint stereoscopic vision algorithm. Extract different images' points from...
