Vehicle Dynamics is a compulsory course of vehicle engineering. At present, the teaching method is still dominated by teachers. There are some problems, such as insufficient engineering oriented teaching content, unable to mobilize students’ learning enthusiasm and so on, which cannot meet the training needs of “New Engineering” for engineers. Based on the concept of project teaching, this paper discusses the teaching content and teaching mode of Vehicle Dynamics, so as to improve students’ part...

In this paper, the front bumper of a certain model was simulated and analyzed in low-speed frontal collision. HyperMesh software was used as the pre-processor, LS-DYNA was submitted for simulation calculation, and HyperView was used as the post-processor to view the output results, so as to analyze the performance of the automobile front bumper in low-speed frontal collision. At the same time, the influence of different beam thickness on collision performance is compared under the same condition...

With the increase of population density and the improvement of human economic level, the emergence of high-rise buildings has put forward higher requirements on infrastructure such as building hydropower, traditional water supply methods have disadvantages such as secondary pollution, unstable water pressure, and high energy consumption. Therefore, variable frequency and constant pressure water supply have gradually become the main method of water supply for high-rise buildings. In order to meet...

The paper describes the dynamic characteristic and fatigue life of the gear meshing. Use the ANSYS to deal with the problem of motion errors which are the result of the wear and the curve caused by the rough surface of the gear generated by the low machining accuracy in the process. And through the analysis, the value and the changing trend of the equivalent stress, fatigue life, and fatigue sensitivity with different friction coefficients can be known. Then it provides an important theoretical ...

This paper presents the performance improvement study of gas turbine power plant in Nigeria by exergy analysis method using Geregu 1 gas turbine power plant as a case study. The study analyzed the system’s components separately in order to identify the sites where the largest exergy losses occur and to quantify the amount. Results of the component efficiencies based on their thermodynamic models of energy and exergy analyses at design and operating years of the power plant revealed that the maxi...

In this paper, spray cooling is the research object, and the component transportation model and DPM model are used in the simulation to simulate the spray and its cooling process to the high temperature heat source. By observing the diameter of droplet and velocity distribution at different heights, the effect of spray on the surface of heat source has been explored. Under the same atomization parameters, the droplet velocity and diameter under different spray distances are quite different. The ...

In the field of machining, the processing design of the cutting parameters has the characteristics of greater subjectivity and experience. For obtaining the ideal roughness of surface (Ra), the number of machining experiments is carried out. It makes a lot of waste of materials, labor, energy, and so on. In addition, there is a highly non-linear function relationship between the three elements of cutting: cutting speed (vc), feed (f), cutting depth (ap) and roughness of the surface. It is hard t...

Numerical computation is one of the reliable ways to solve partial differential equations. In the past three decades, with the rapid growth of computer processing power and storage space, numerical computation has been successfully applied to many fields. It provides strong support for researchers to solve complex engineering practical problems and analyze complex physical phenomena. Most of the existing numerical methods are element-based, among which the finite element method is the most famou...

In the previous paper [1], the formula of the contact pressure distribution in the steady wear state for drum brake system was derived. The contact pressure distributions on the leading and trailing shoes were found to be different and larger on the leading shoe. Using these contact pressure distributions, it is easy way to calculate the braking torque. Assuming the varying position of the shoe pin, the optimization problem can be formulated by requiring the optimal pin position corresponding to...
