Theoretical digging force is an important performance parameter of the hydraulic excavator. Due to the multi-linkage mechanism, the digging posture of an excavator is ever-changing; thus, it is not easy to calculate the theoretical digging force. Traditionally, the theoretical digging force is calculated by selecting a limited number of postures of the excavator based on experience, which cannot reflect the force condition of each posture in the excavation process. In order to calculate the theoretical digging force of any posture in the excavation process, this paper uses the principle of the analytical method to establish a theoretical excavation force mathematical model of bucket excavation and uses Matlab software to solve the theoretical excavation force mathematical models. In order to verify the model’s correctness, the experimental method is used to determine the actual maximum excavation force of the excavator. The test results showed that there was little difference between the actual maximum digging force and the theoretical maximum digging force, which verified the correctness of the theoretical digging force mathematical models and provided a theoretical digging force calculation method and reference for the structural design and optimization of the excavator....
The present work seeks to develop a model for measuring efficiency of RCBs in Ghana by means of financial key performance indicators pairing macroeconomic indicators. A stochastic differential equation model for predicting the efficiency of RCBs in the future is developed and simulated using gaussian jumps to evaluate the models’ performance in unpredicted situations with four distinct phases of efficiency. Unique solution Exit multiple 4-dimensional stochastic differential equations and Macroeconomic model is proven to be the best-fitting model for the data with the lowest information criterion....
At present, the application of information technology has realized the transformation of people’s production and lifestyle, and it has also promoted the transformation of the sports industry. At present, the application of informatization in the basketball field in the sports industry is increasing. By using the advanced methods and technologies of its information display, this article aims at realizing the optimization of the basketball recognition pattern in the mobile network communication environment to promote the ecological development of the sports industry. It proposes to use panoramic vision to guide the integration of computer network and basketball field, which is helpful to analyze and solve the objectivity problems of single action and system incompatibility in basketball recognition simulation. By referring to the principles and laws of panoramic vision, the identification module and simulation module of the basketball auxiliary training system are constructed and optimized, so as to realize the promotion of basketball and the ecologicalization of teaching. In the research on the basketball recognition simulation system, the three-dimensional skeleton key point coordinate data are input into the ST-GCN network for comparison and testing. Specifically, it includes 2D key point coordinate data and 3D key point coordinate data as input to conduct model research and testing in the self-made basketball dataset. The experimental results show that the recognition rates of 2D and 3D coordinates are 66.64% and 87.69%, respectively. Therefore, it is crucial to use the human panoramic vision algorithm to convert 2D coordinates to 3D coordinates....
With the continuous development of the social economy, people from all walks of life attach great importance to the smart home design of artificial intelligence technology. In the context of the information age, people’s requirements for the quality of life are also gradually upgrading, and the requirements for home furnishing have also been upgraded from the traditional requirements of only living places to the expectation that a more intelligent, convenient, smart home has gradually been brought into life by people. The smart home system can integrate all control terminals into one system and implement on-site or remote control of home equipment using the computer terminal and mobile phone terminal, to realize the function of managing home equipment more conveniently and flexibly. Artificial intelligence technology as one of the important links adopts a structured design scheme to control and complete the design of the smart home system. Compared with most smart home systems on the market, this system also focuses on the safety precautions of the residential environment. It adopts infrared detectors for doors and windows and gravity sensing devices for indoor floors. The space-time barriers between home systems optimize and enhance the user’s living experience. The article first analyzes the architecture, mainstream technology, and characteristics of computer technology and then discusses the design and implementation of my country’s smart home system, providing strong support for subsequent research....
In order to further promote the design and development of 3D simulated garden landscape, the author proposes a method of 3D simulated garden landscape design based on virtual simulation technology. By combining virtual simulation technology and traditional 3D simulation garden landscape design method, a 3D garden landscape simulation system is constructed, thereby realizing the improvement of 3D simulation garden landscape design method and further promoting the development of 3D simulation garden landscape design. Experimental results show that with the gradual expansion of the scope, the accuracy of the method used by the author gradually improved, reaching a maximum of about 89%, while the traditional method was always maintained at about 40%, and the judgment rate was doubled compared with the traditional method. Conclusion. By combining virtual simulation technology and traditional 3D simulation garden landscape design method, the development of 3D simulation garden landscape design can be effectively promoted....
