Effects of Initial Crack Defect on Fatigue Crack Growth of Camshaft for Nuclear Emergency Diesel Engine
Authors: Zhao Minghuang , Duan Chenghong , Han Xiangxiang , Luo Xiangpeng 
Published: December 2019

Abstract
In this paper, the finite element analysis model of camshaft for nuclear emergency diesel engine with initial crack defect is established based on ABAQUS finite element analysis software. The effects of initial crack defect parameters on crack tip stress intensity factor are studied by a working condition discretization method. The numerical results show that the crack tip stress intensity factors of transverse crack and longitudinal crack are quite different in a load cycle of camshaft. The crack tip stress intensity factors of transverse crack fluctuate greatly, and the crack tip stress intensity factor range is much larger than that of longitudinal crack, which indicates that the fatigue fracture risk of transverse crack on the camshaft journal is higher. With the increase of initial crack depth from 1 mm to 4 mm, the crack tip stress intensity factor range increases from 410.84 MPa·mm1/2 to 720.24 MPa·mm1/2 by 75.3%, which indicates that the increase of initial crack depth can lead to a significant increase of the fatigue fracture risk. As the initial crack defect moves away from the cam, the maximum of the crack tip stress intensity factor initially increases and then decreases after reaching a maximum value. When the initial crack is 3 mm away from the end face of the cam, the crack tip stress intensity factor range is the largest (843.98 MPa·mm1/2), which indicates that the fatigue fracture risk of transverse crack at this position is the highest. The research results obtained in this paper may provide some reference for the fracture assessment and reliability analysis of camshaft for nuclear emergency diesel engine.

Authors: Liu Yixian 
Published: December 2019

Abstract
At present, the operation adjustment of the power distribution system of the power station boiler mainly relies on the experience of the operators and the optimization and adjustment test, neither of them can be economically and flexibly adapted to the current situation of complex boiler combustion conditions and strict environmental protection indicators. To reduce the NOx generated by pulverized coal combustion in the furnace, this paper effectively combines the big data mining technology with the boiler combustion system based on the best ratio of coal-air. Taking the double-cut circular boiler designed by a 1000MW thermal power unit as an example, we use Apriori algorithm to mine the association rules in historical operation data and develop software to guide the operation of the operator. By calculating, the NOx content of the SCR inlet after adopting the optimization scheme is reduced by about 17%. Combined with the “cost-benefit analysis of denitration technology” spectrum, the denitration cost is reduced by about 200, 000 yuan per month.
Study on Stability and Durability of Coal Gangue Used in Runway Base
Authors: An Yong 
Published: December 2019

Abstract
Coal gangue, as industrial waste generated in the mining process, is rarely used in the construction of domestic airport runways. This paper studies the stability of coal gangue and the durability of cement stabilized coal gangue in combination with the characteristics of navigation airport construction. The coal gangue self-stability test includes: chemical composition, loss on ignition, crushing value and expansion ratio. The durability of cement stabilized coal gangue is mainly based on the freeze-thaw cycle test. The test results show that the sum of the content of coal gangue SiO2, Al2O3 and Fe2O3 in the mine is more than 70%, the loss on ignition is less than 15%, the control standard can be achieved, and the expansion ratio is not more than 0.5%. Coal gangue itself has good stability. By comparing the compressive strength values of the standard test pieces before and after 6 freeze-thaw cycles, it is found that the cement-stabilized coal gangue with different cement content has a frost resistance of more than 60%, and the overall frost resistance is good. In addition, considering the load level and safety reserve of the navigable airport, the cement content should be greater than 5%. The above conclusions can provide reference for the application of coal gangue in the field of airport construction.

Authors: Cao Zhiqiang , Ai Chunan , Wang Xueren , Li Jian 
Published: December 2019

Abstract
High-efficiency pre-cooler is one of the key components of RBCC combined engine. To explore the influence of tube row curvature on heat transfer, a convection heat transfer simulation of pre-cooler composed of different curvature tube rows is established. The model and numerical calculations show that when the curvature is small, the heat transfer efficiency increase slowly with curvature increasing, but the flow resistance increase obviously by increasing curvature. However, when the curvature is large, the effect of curvature increasing on the heat transfer efficiency is obvious and the increase of flow resistance get slower. Based on this, a ring pre-cooler is designed and the heat transfer effect is simulated. It has reference application value for the design of high efficiency pre-cooler.

Published: December 2019

Abstract
The hydrogen supply system is the energy supply of hydrogen-powered vehicle. The failure of most parts in the hydrogen supply system is due to the impact and vibration caused by complex road conditions. Therefore, it is required that the hydrogen supply system should have good impact and vibration resistance. In this paper, the Design Exploration module in ANSYS Workbench is used to study the multi-objective optimization about the stiffness and strength of a two-bottle horizontal hydrogen supply system under impact and vibration conditions. The responding surface between the width and length of the frame and the stiffness and strength of the system under different conditions is developed. The optimal frame size which can effectively reduce the stress state of the system structure under impact and vibration condition is obtained.

Published: December 2019

Abstract
The finite element simulation of the selective laser melting process with Al6063 metal powder was carried out by using ABAQUS. The loading of the laser Gaussian moving heat source is realized, and a model of the three-dimensional transient temperature field is established. The effects of scanning speed and scanning pitch on temperature distribution and temperature changes on different scanning channels were investigated. The simulation results show that due to the heat accumulation effect and heat conduction, the previous scan will have effect on the surrounding powder, which results the rise of temperature. Different scanning speed and the scanning pitch have influence on the temperature distribution. As the scanning speed increases, the temperature gradually decreases, and the increase in the scanning pitch also lead to lower temperature of the powder layer.

Abstract
The estimation accuracy of single extended Kalman filter is not high, also it is affected by the initial value of state of charge (SOC). The second-order RC equivalent circuit model of lithium battery is established, and a joint algorithm, dual extended Kalman filter (DEKF) is proposed.

Abstract
Artificial intelligence algorithms such as ant colony algorithm and neural network do not need to rely on a large amount of gradient information when solving, especially for large-scale complex optimization problems which are difficult to solve by traditional methods, which provides a new perspective and thinking direction for solving such problems. Based on the analysis of the principles and advantages and disadvantages of RBF neural network and ant colony algorithm, this paper proposes a RBF neural network based on genetic mutation improved ant colony clustering algorithm to evaluate the location of charging station. The improved ant colony clustering algorithm based on genetic variation is used to determine the number of hidden layers of RBF neural network, so as to solve the problem that the initial parameters of RBF neural network can not be accurately selected without scientific methods. An example is used to prove the scientific and effectiveness of this method. Finally, the optimal scheme of charging station location is determined by comparing the comprehensive ranking values obtained by various methods used in this paper to judge the advantages and disadvantages of charging station location.
