Abstract Many packaging cushion materials follow the hyperbolic tangent type of constitutive relation, so a stiffness non‐linearity was derived to describe property package. Transport package modelled as single degree freedom (SDOF) spring–mass–damping (SMD) system. The displacement and velocity responses system were obtained by Fokker–Planck–Kolmogorov (FPK) equation. Based on kinematic equation integral transforming, approximate analytic solution acceleration response power spectral...
Analytical probability density function of acceleration random response for cubic nonlinear product package has seldomly been investigated due to the difficulty solving problem and less attention paid response. In this paper, analytical solution linear under vibration is obtained, on basis, equivalent linearization method introduced further explore approximate vibration. Some suggestions packaging optimal design are given by analyzing sensitivity external excitation system parameters,...
A new approach is proposed to analyze the non‐Gaussian random vibration of hyperbolic tangent package. Firstly, noise specified mean, variance, skewness, and kurtosis developed by Hermite polynomial verified Gaussian mixture model theory. Secondly, next analyzing an analytical numerical response two degrees freedom linear package, acceleration package system under excitation obtained though Runge–Kutta method, effects external parameters are investigated. Finally, on basis first‐passage...
As an effective method for solving nonlinear problems and simulating models, Monte Carlo (MCM) has attracted more attention in recent years, which been successfully applied fields such as electrical electronic engineering, physical chemistry, material science geophysics. In this paper, the research progress of MCM is introduced based on analysis literature field Citespace. Based visualization results, Evolution Law Research, hotspot future trend are discussed. This study will provide...
This paper focuses on the dynamic response of three asymmetric and nonlinear packaging systems (ANPSs) practical transport package under random excitation. Next to presenting displacement probability density functions (PDFs) ANPSs derived through FPK equations, influences excitation grades characteristic parameters (such as damping, stiffness, strain) cushion materials are discussed in detail. Then, generalized PDFs peaks defined examined by common distributions. The investigation shows that...
This paper reveals the dynamical properties of a Gaussian and non-Gaussian vibration excited multi-degree-of-freedom (MDOF) discrete product packaging system (DPPS) with hyperbolic tangent nonlinearity base on more systematic acceleration response analysis. Firstly, package considering multiple critical components is modeled as general model MDOF DPPS, centered around opposite designed purpose similar tuned mass damper (MTMD) model, in which rarely considered, then approximate solution...
AdaBoost regression predicts the ranking of college students using super star learning APP
Environmental factors especially relative humidity play an important role on the energy absorption performance of honeycomb paperboard. The characteristics and system theories diagrams containing factor paperboard are investigated. Energy were constructed based practical static compression test MATLAB simulation at four conditions (30%, 50%, 70% 90%). A good agreement is achieved between theoretical experimental curves. both by experiments mathematical models show that increase...
An important proportion of the audiences ideological and political WeChat public are young people, “youth subculture” which has a great influence on number prevailing among audience youth. "Guangdong students' federation" "Jinan University Youth League Committee" selected to do comparative study transforming use youth subculture, its advantages deficiencies can be explored, transformation utilization subculture optimization recommendations drawed.
Since markov chain is widely used in various fields, the relevant literatures of theories are analyzed base on CiteSpace this paper, adopting 10,000 CNKI and WOS as datas. The relationship among chain, monte carlo integral bayesian theory primarily. What's more, hidden model, random field, decision process grey-markov model derived from investigated emphatically. Ultimately, we reviews development history makes a visual analysis authors, sorts out research status comprehensive review...
A new approach is proposed to analysis the non-Gaussian random vibration of hyperbolic tangential package. Firstly, noise specified mean, variance, skewness and kurtosis developed by Hermite polynomial, verified Gaussian mixture model (GMM) theory. Secondly, next analyzing an analytical numerical response two degrees freedom (TDOF) linear package, acceleration TDOF package system (HTPS) under excitation obtained though polynomial Runge-Kutta method, effects external parameters are...
Background Our study is to determine the correlation between preoperative MRI parameters of spinal cord compression and effects anterior surgery in patients with degenerative cervical myelopathy (DCM). Methods 24 normal subjects no evident abnormalities were selected as group A. 79 DCM underwent single-segment (C4–5/C5–6) ACDF formed operation group, separated into B (without high signal) C (with according absence or presence signal on T2-weighted respectively. (MCC, maximum canal...
