Abstract: This study aims to explore the application of fiber optic grating sensors in wearable human physiological parameter acquisition systems, providing technical support for health management and medical assistance services. The appropriate packaging method of this design ensures that the fiber optic grating will not be unnecessarily damaged in non detection states, and the deformation is only caused by the deformation of key parts of the human body. With compensation for human body temperature, the strain at the point to be measured can be measured. Therefore, a design concept of embedding fiber optic grating sensors into clothing is proposed, which enables the collection of physiological parameters of the human body through wearing clothing. It has strong anti-interference ability, high accuracy of measurement results, can be measured repeatedly, and has minimal impact on normal human activities.Abstract: This study aims to explore the application of fiber optic grating sensors in wearable human physiological parameter acquisition systems, providing technical support for health management and medical assistance services.

Abstract: With the progress of science and technology and the development of AI intelligence, simple cleaning is no longer the only demand for home cleaning robots. The multifunctional housekeeper robot home guards based on home living environment and intelligent AI control have become a new research direction. Based on the analysis and summary of the existing household cleaning robots, the market demand for cleaning robots is to finish cleaning the ground efficiently in the shortest time, but the improvement of cleaning efficiency will seriously affect the service life of the robot structure. Therefore, when the structural design of household cleaning robot is completed, the stiffness calculation and static analysis of key components are considered. Through the structural design of walking, cleaning and vacuuming devices, the robot can complete cleaning and vacuuming functions by moving, and the path planning of the robot is made by using the AI intelligent housekeeper function to improve the cleaning efficiency of the robot. Through the stiffness calculation and static analysis of the gear and transmission rod in the transmission mechanism, the feasibility of the design is verified, and the technical guidance is provided for the structural optimization and material selection of the later robot manufacturing. Combining AI intelligent control with robot structure design, the robot performance is continuously optimized, so as to ensure that the robot has a long service life while completing cleaning tasks efficiently and meet people's demand for home cleaning robots.Abstract: With the progress of science and technology and the development of AI intelligence, simple cleaning is no longer the only demand for home cleaning robots.

Abstract: In order to solve the wear problem of hydraulic coupling bearing bush encountered in practical work, the common characteristics of several wear failures of hydraulic coupling bearing bush are analyzed, through the lubricating oil quality, lubricating oil temperature, bearing clearance, bearing overload, gas in the oil, lubricating oil volume and several aspects of one by one, and the journal and bearing bush expansion is not synchronous resulting in bearing bush clearance reduction for analysis and calculation, bearing bush overload for analysis and calculation, oil film thickness for analysis and calculation. The results show that the main reason for the wear of the hydraulic coupling bearing is that the pump unit is quickly loaded to the rated load after starting at a low lubricating oil temperature, resulting in the journal and bearing expansion being out of synchronous, resulting in an instantaneous reduction of the bearing gap, and the additional load generated by superimposed acceleration causes the bearing overload, resulting in the minimum oil film thickness being reduced to the critical oil film thickness, and finally causing the bearing wear. In addition, Bearing clearance at the lower limit of the design range and the uneven load distribution of 5 and 6 watts are the contributing causes of bearing wear. The feasible treatment measures are given for the wear of the bearing bush of the hydraulic coupling, which can be dealt with from the three aspects of increasing the lubricating oil temperature, extending the pump speed increase time, and appropriately increasing the clearance of 5 bearing, avoiding the occurrence of wear failure of the bearing shells of the hydraulic coupling.Abstract: In order to solve the wear problem of hydraulic coupling bearing bush encountered in practical work, the common characteristics of several wear failures of hydraulic coupling bearing bush are analyzed, through the lubricating oil quality, lubricating oil temperature, bearing clearance, bearing overload, gas in the oil, lubricating oil volume and se...Learn More
