Abstract: In this paper, a Carsim/Simulink co-simulation model of a four-wheel independently driven electric vehicle braking system is established to simulate the process of vehicle linear braking. The traditional Carsim car model was modified into a four-wheel independently driven electric car model, and then the torque control model, braking distance calculation model, driver signal judgment model, and braking force calculation model were built in Simulink to realize the establishment of the closed-loop system. The correctness and stability of the model are verified by the co-simulation experiment. This model lays a good foundation for the research of the control algorithm in the future.

Abstract: Natural rubber (NR) is widely used in military industry, aerospace industry, medical equipment and other fields. Carbon nanotubes (CNTs) were selected as nano fillers and NR / CNTs nanocomposites were prepared by mechanical mixing method. Based on the relationship between structure and properties, the effects of CNTs addition on the micro properties, vulcanization properties, mechanical properties, wear resistance and solvent resistance of the nanocomposites were investigated by means of mechanical property test, transmission electron microscopy (TEM), thermogravimetric analysis (TG), dynamic mechanical property test (DMA). The results showed that: TEM observation showed that CNTs dispersed uniformly in NR matrix, and the two phases had good compatibility; with the increase of CNTs content, the mechanical properties and solvent resistance of the nanocomposites increased significantly TG analysis showed that the nanocomposites had excellent thermal stability, and the comprehensive properties showed that the optimal amount of CNTs was 3 phr.

Abstract: The Internet industry is one of the most promising emerging industries in China, and its financial risk is related to the sustainable development of the company. This paper toke 45 Internet listed companies as research samples, and selected 14 financial indicators from five aspects to study their financial risks in 2019. Factor analysis was first conducted with the help of SPSS24.0 software by constructing a financial risk evaluation model and scoring and ranking according to the factor score model. Then the 45 companies were classified into four categories according to the magnitude of comprehensive financial risk: almost no risk, less risky, more risky and very risky by the K-means clustering method. Finally, corresponding countermeasures are proposed for the risk problems commonly existing in Internet listed companies.

Financial Performance Evaluation of Electric Power Listed Companies Based on Principal Component Analysis
Author: Zhibin Liu, Yue Bai
Author affiliation:
Department of Economics and Management, North China Electric Power University, Baoding, China.

Abstract: In this paper, 64 electric power listed companies in China are selected as the research objects, and 11 indicators reflecting the financial development of electric power listed companies in China are selected to evaluate the financial performance of electric power listed companies in China by principal component analysis. Four principal components are extracted from the relevant financial data, and then the score and ranking of the comprehensive financial performance of the 64 power listed companies are obtained. The current situation of the financial performance of China's power listed companies is comprehensively and objectively evaluated through the analysis of the scores and rankings. It provides the basis for the listed companies in China's power industry to take effective measures to solve the problems and improve their comprehensive ability.
