Abstract: To solve the safety problems of the plug and row caused by touching the water and mistakenly touching, which leads to the hidden danger of electricity for high-power electric heating equipment, charging type electric equipment and the life of the socket itself is reduced and the electricity is wasted, this paper proposes a design based on the orbital plug and row pressed to eject the plug and STC89C52 as the core of the wireless control smart socket, wireless communication control using NRF24L01 chip. Among them, this design mainly designs and analyzes the mechanical structure of the plug and combines the static theory to optimize the structure of the plug and realize its feasibility. Solid Works software is used to model the plug and row in three dimensions, and its mechanical components are analyzed statically to obtain a cloud diagram of the force and deformation of the cam structure of the plug and row under the load condition. Finally, the deformation cloud diagram of the socket under various working conditions is used to verify the rationality and feasibility of the wheel system structure in the socket. The design mainly uses the cam structure to press the pop-up and orbital disc socket, and the biggest features of this socket are safety, reliability, and economy.Abstract: To solve the safety problems of the plug and row caused by touching the water and mistakenly touching, which leads to the hidden danger of electricity for high-power electric heating equipment, charging type electric equipment and the life of the socket itself is reduced and the electricity is wasted, this paper proposes a design based on the orbit...Learn More
Abstract: To meet the demand of providing basis for improving triaxial vibration system, it is necessary to extract the overall Frequency Response Function (FRF) matrix of triaxial vibration system from its digital model. The mechanical parts of triaxial vibration system is connected tightly which satisfy rigid connection assumption. The Jetmudsen FRF method is used to construct the overall frequency response function matrix of triaxial vibration system. The electrodynamic shaker (referred to as the shaker) is an important component of the three-axis vibration system, and its function is to provide the test bench with an excitation force in a certain direction. Therefore, it is necessary to define a large number of internal nodes on the shaker. The FRF matrix of shaker (including origin FRF matrix of internal nodes and joints, cross-point FRF matrix of internal nodes and joints) should be obtain to carry out the construction of overall FRF matrix of triaxial vibration system. It is difficult because the size of FRF matrix of shaker is too large. So a way to simplify the distributed loads exerting on the structure into multi-point concentrated loads is proposed, it can be used to obtain the simplified digital model of the electrodynamic shaker. Based study above, the overall frequency response function matrix of the triaxial vibration system is obtained, and the digital modeling of the triaxial vibration system is completed.Abstract: To meet the demand of providing basis for improving triaxial vibration system, it is necessary to extract the overall Frequency Response Function (FRF) matrix of triaxial vibration system from its digital model.
