Reliability analysis of multistage transmission system with coupling uncertainties
Authors: Wang Yuehua , Xiong Xin , Hu Xiong 
Published: January 2021

Abstract
The coupling uncertainties have already become the greatest difficulty in assessing the reliability of multistage transmission systems. A new reliability assessment method of rotor system with uncertainties is proposed here. The probability density functions (PDF) of the state functions are re-derived by introducing the divergence control parameter of uncertainty from nonparametric modeling method and the Lagrange multipliers involved are calculated by the Sigel function method. Then, the joint PDF of all state functions is calculated so that the reliability prediction of multistage systems can be effectively carried out. Both the coupling uncertainties and the intensity of uncertainties are formulated in the PDF of the state functions. Furthermore, the short-period prediction method is improved to avoid wrong judgments caused by excessive neighbor radius. Numerical simulation suggests a reference for which degree of uncertainty can be accepted. It’s very helpful to predict the evolution of operation status and avoid the occurrence of faults.

Published: January 2021

Abstract
The contact simulation model of high-speed railway train axle box bearing is simplified into a two-dimensional plane with an elastic semi-infinite body subjected to semi-elliptical cylindrical compressive stress in one direction. The ANSYS software was used to solve the effects of single inclusion size, the depth of the contact surface and the elastic modulus on dynamic shear stress and Von Mises stress of high-iron bearing subsurface, and compared with the calculation results of bearing material uniformity assumption. Using the modified Basquin equation, the relevant assumptions are made. The maximum Von Mises stress is used as the key stress for fatigue life calculation. The bearing fatigue life calculation method is established to study the influence of the inclusion size, the depth of the contact surface and the elastic modulus on the bearing fatigue life.

The conditions were drying temperature 58.70°C, drying time 8 h 48 min, and xylose solution concentration 50.70%. Subsequently, effects of drying conditions on physical properties of dried Aronia melanocarpa (DAM) were evaluated in Scanning electron microscope (SEM), Fourier transform infrared spectrum (FTIR), X-ray diffraction (XRD) and Different scanning calorimetry (DSC). The physical properties showed that DAM with xylose changed from amorphous to crystalline during drying process, which would extend the shelf life of DAM. Besides that, the physical properties results also showed that a Maillard reaction occurred during drying, which explained the improved antioxidant capacity of DAM with xylose. The results showed that xylose could reduce spoilage, prolong shelf-life of DAM, and indicated its use as a potential functional ingredients in the food industry.

Authors: You Yi , Zhang Long , Yan Zhitao , Nie Xiaochun , Wang Feng 
Published: January 2021

Abstract
In order to ensure the accuracy of the test and avoid the errors caused by the slip between the steel and aluminum materials, the mechanical properties of ACSR at different temperatures were studied by the method of separate experiment of steel strand and aluminum strand. The test results show that with the increase of temperature, the elastic modulus of aluminum strand and steel strand decreases, but the elastic modulus of steel strand decreases more. There is no obvious strengthening stage and yield stage for aluminum strand, but obvious elastic stage, yield stage, strengthening stage and local necking stage for steel strand. The failure parts of aluminum strands are concentrated in the position of 1 / 2 ∼ 1 / 3 of the samples, and the failure parts of each strand tend to develop along the twisting direction. The failure position of the steel strand is basically in the same cross section of the middle area of the sample. The experimental results of steel and aluminum strands are basically consistent with the results of the whole steel reinforced aluminum strand, which proves that the experimental method is feasible.
