In this study, the properties of controlled low strength material (CLSM) made from waste soil were examined, utilizing 53 different mix proportions, and a dataset was subsequently constructed. Models, such as particle swarm optimization (PSO)-support vector regression (SVR), genetic algorithm (GA)-SVR, grid search (GS)-SVR, developed to predict both flowability unconfined compressive (UCS). To assess models' performance, comparisons between experimental predicted values, residual...
An interleaved high step‐up zero‐voltage‐switching boost converter is proposed in this study. The operating principle and voltage gain ratio of the are presented. variable inductor control method used to regulate output achieve a high‐voltage gain. design procedure with double E core also presented detail. Finally, 40 W prototype 12 V input 100 built verify consistency theory analysis. highest efficiency measured 84.5%.
In this work, we first studied the thermal damage to typical rocks, assuming that strength of thermally damaged rock microelements obeys a Weibull distribution and considering influence temperature on mechanical parameters; under condition microelement failure conforms Drucker–Prager criterion, statistical constitutive model rocks after high‐temperature exposure was established. On basis, conventional triaxial compression tests were carried out oil shale specimens heated different...
Gears fabricated using powder metallurgy technique (PMT) have the potential to replace traditional wrought gears due their very high forming efficiency and relatively low cost. However, practical applications are restricted lack of understanding fatigue properties failure mechanisms. This work investigates contact performance corresponding mechanism a typical Fe-based small-module by PMT. The tests were conducted under grease lubrication condition, power-opened gear testing rig. experimental...
Abstract In response to the improvement of penetration ability for kinetic energy projectiles, projective structures have been continuously increasing in thickness and developing direction composite-medium materials, resulting complexity testing overload characteristics detonation control system. Addressing this difficulty, paper analyses range test data high-speed deep thick target. It is found that has long pulse width multiple peaks, which quite different from penetrating single-medium...
Cracking frequently encountered in railway bridges can lead to significant changes bridge dynamic characteristics and further performance of train–bridge interaction (TBI) system. It is desirable develop an effective method understand the behavior coupled train cracked systems. This paper proposes a framework for vibration analysis systems using multiscale finite element modeling. A model adopting frictional surface–surface contact characterize nonlinear breathing phenomenon crack...
The design scheme and fabrication technology of the detonation control system for high-speed deep penetration need to be tested reliability effectiveness through shooting range tests. However, tests are so demanding expensive that it is difficult many times. This paper focuses on characteristics put forward a laboratory-scaled experiment method with low impact velocity. Independent parameters projectile target affecting effectively analyzed extracted. A multi-parameter programming scaled...
In this paper, we propose an analytical method to predict projectile penetration and perforation based on the Differential Area Force Law (DAFL) semiempirical resistance function.Due free surface effect, in order account for differences of target resistances acting top bottom sides projectile, obtain theoretic solutions a dynamically expanding spherical cavity finite sphere incompressible Mohr-Coulomb material.The proposed methodology is implemented ABAQUS explicit solver via user...
