As engineering systems become increasingly complex, reliability-based design optimization (RBDO) has been extensively studied in recent years and made great progress. In order to achieve better results, the mathematical model used needs consider a large number of uncertain factors. Especially when considering mixed uncertainty factors, contradiction between computational cost efficiency algorithm becomes fierce. How quickly find optimal most probable point (MPP) will be an important research...
Objective: To evaluate and analyze the actual efficacy of percutaneous vertebroplasty in treatment old unstable osteoporotic spinal fractures. Methods: From March 2023 to 2024, 46 patients with fractures our hospital were included this study. They divided into conventional group observation based on differences, 23 each group. The received conservative drug therapy, while underwent vertebroplasty. following indicators compared analyzed between two groups: clinical effect improvement physical...
Aimed at addressing the issues of cage instability and excessive skidding cylindrical roller bearings under high-speed light-load conditions. Dynamic Time Warping method was employed to quantitatively assess stability motion by calculating similarity between tracks mass center. Additionally, effects force on whirling characteristics were analyzed various states. The findings indicate that is most stable during local periodic whirling, followed regular circular whirling. acting cage, which...
The utilization of desert sand for making ceramsite lightweight aggregate concrete is proposed to make full use local natural resources in the development a new type and load‐bearing wall material with good energy conservation, waste utilization, thermal insulation performances. An orthogonal test was conducted analyze effects water‐binder ratio, substitution rate, fly ash content on slump, apparent density, tube crushing strength concrete. Thus, optimal mixture ratio obtained LC20 LC25...
The gas bubble size, local phase holdup, and other flow characteristic parameters of the gas–liquid–solid circulating fluidized bed play an important role in design operation this type reactor. However, due to limitation measurement techniques three-phase fluidization, characteristics have not been well measured studied. In recent years, telecentric imaging technology has applied multiphase systems, a new probe method used measure expanded bed. work, measuring was introduced holdups size...
Abstract Feature extraction from vibration signals plays a vital role in rotating machinery fault diagnosis. The noise contained the will interfere with feature result. Wavelet denoising (WD) is commonly used method to reduce noise, but its parameters are generally selected based on subjective experience. With this problem mind, an adaptive wavelet (AWD) proposed paper. Using permutation entropy evaluate signal level and taking minimum value as fitness function, whale optimization algorithm...
With the engineering system becoming more and complex, uncertainty factors have a profound influence on reliability security of system. In recent years, Reliability-Based Design Optimization (RBDO) has been studied extensively in complex design. The research optimization design considering stochastic comprehensive widely used. However, mixed disadvantages large computation imprecise convergence. This study proposes an RBDO method based Particle Swarm (PSO) Simulated Annealing (SA) to...
To improve the efficiency of safety tests driver-automation cooperation, a method for generating scenario library is proposed that considers probability occurrence and driver-handling challenges in real driving situations. First, original data under cut-in conditions stored time series are extracted from set. Then, mathematical performance index used to model significance function terms frequency scenario, challenge between driver vehicle established. Next, important set by constructing...
This paper explores the cage whirl state under different operating conditions based on cylindrical roller bearing dynamics model. The stability and characteristics of are evaluated by considering rotation force roller. results demonstrate that is divided into three types according to orbit: disordered whirl, local periodic regular circular whirl. With speed radius unpredictable, changes frequently. speed, change periodically or stay constant. In case a should be considered evaluate addition,...
In the multi-weapon platform cooperative combat conditions, coordination of weapons between different platforms in order to quickly calculate launch time all become very urgent and extremely difficult. To solve problem multi — weapon scheduling, mixed integer programming model attack targets is established by minimizing final platform. A fast heuristic algorithm based on task priority designed, which can provide commander with firing timing scheme strike requirement. trajectory...
