With the development of miniaturization of equipment, the equipment in the shelter has higher and higher requirements for heat insulation. The liquid cooling system can effectively improve the heat insulation ability, but the cooling system has a large weight, and the rigidity and strength requirements of the outer shelter structure are high, especially the hoisting state of the shelter, which is a dangerous working condition during the use of the shelter. This type of shelter should focus on the load-bearing area during the design process, and combine the finite element method to verify the simulation and improve the design efficiency. For the characteristics of the layout of a certain type equipment shelter, a special design is presented in this paper. The area with large load was partially strengthened, and the finite element model of the shelter skeleton was established under the premise of reasonable simplification. The stiffness and intensity of the shelter structure were analyzed by finite element method. The analysis results shows that the type of the shelter is reasonable and feasible, and the finite element method has a strong guiding significance in structural design, it also shows that the finite element method can effectively improve the design quality.

In this paper, it is used to simulate and analyze the telescopic boom structure of a bridge inspection vehicle by HyperWorks software, to solve the problem that the bridge inspection vehicle is heavier and the stability is slightly insufficient, due to the increase of operating parameters. According to the analysis results, it is carried out to optimize the boom by using topological optimization. Compared with the previous, the weight of the telescopic boom is reduced by 16%, the stiffness is increased by 5%, the strength is increased by 10%, and the stability of the whole vehicle is increased by 2.7%. The simulation results are in good agreement with the test results, which proves the safety and reliability of the optimization scheme.

Aiming at the complex structure and weak real-time performance of traditional visual tracking system, a scheme based on PYNQ (Python productivity for Zynq) framework is designed and deployed in Zynq heterogeneous platform. Firstly, according to the real-time requirements, the kernel-related filter tracking algorithm is selected. Then, according to the characteristics of the Zynq computing platform, the software and hardware collaborative design method is used to divide the system tasks, and the algorithm is converted into RTL (Register Transfer Level) by HLS (High Level Synthesis) development tools, and the calculation is performed. The process is optimized and exported as an IP core. Then, Python is used to import the IP core as a hardware coprocessor at the top level to implement the underlying to top-level data interaction. Finally, the system result is asynchronously updated in the Jupyter notebook. Experiments show that the system has good real-time performance, and the tracking speed averages 27.9FPS. At the same time, it has superior execution efficiency, is easy to develop and transplant, and has certain engineering reference value.

The thermal state of the automotive Li-ion battery requires to be monitored by the thermal management system for safety purpose. This paper presents a pseudo two-dimensional model for a 18650 cylindrical Li-ion battery to estimate heat generation and predict the transient temperature at 2C discharge and charge rates based on the electrochemical-thermal coupling analysis. For experimental validation, the 18650 cylindrical lithium-ion battery cell is tested under high and low temperature alternation inside the closed chamber whose temperature is under control. Various kinds of heat generations of the battery at different working conditions are achieved during charging and discharging at a rate of 2C. The temperature change estimated by the model is in good agreement with the experimental data. Therefore, the proposed thermal model provides a reliable temperature estimation of Li-ion batteries, which is sufficient accurate for the thermal management of the automotive battery. Moreover, the calculation cost of the proposed thermal model is evaluated and proven to be small enough for engineering application in the thermal management.
