The flexible hinge is a mechanical component that utilizes the micro-elastic deformation and recovery characteristics of metal. It is a high-resolution transmission mechanism that allows for precise positioning and fine-tuning. It is commonly used in devices such as precision positioning platforms, photolithography equipment, and scanning detection microscopes.
There are several factors that can affect the performance of flexible hinges. When designing flexible hinges, some assumptions are made, such as assuming that only elastic deformation occurs at the hinge and that the rest of the structure is rigid. It is also assumed that only corner deformation occurs during operation, without any expansion or other deformations. However, the hinge itself has inherent defects, such as the center of rotation not being fixed, stress concentration, and stress magnitude changes with the position of the joint. The material properties and environmental factors can also impact the performance of the hinge.
In structural design, the combination of multiple hinges and connecting rods is common. However, the processing errors between these combinations can lead to coupling displacement of the corners and straight lines, causing the motion of the mechanism to deviate from the desired path. There have been comprehensive analyses of the error sources in flexible hinge mechanisms, including discussions on material performance, size design, vibration, interference, machining errors, etc. These analyses aim to understand the sensitivity of each variable error on the performance of the flexible hinge.
Previous research has used methods such as the Taylor series expansion, finite element method, and numerical simulations to study the displacement mechanisms and coupling caused by manufacturing errors in flexible hinges. However, most of these studies focused on individual mechanisms and had certain limitations in terms of the scope and results obtained.
This paper focuses on the analysis of three machining errors in straight circular flexible hinges: the positioning error of the incision arc in the y direction, the positioning error of the incision arc in the x direction, and the perpendicularity error of the center line of the arc axis. The stiffness calculation formulas for each type of error are derived, and the results are validated using finite element analysis (FEA). This research provides valuable insights into the parameter design and processing of hinges.
To conduct the analysis, a cantilever beam structure model is established using ANSYS software. Different design points are obtained by modifying the error parameters, and simulation calculations are carried out on these design points to obtain the stiffness errors. The results obtained from numerical analysis and finite element analysis are compared and found to be in good agreement.
The results show that the errors in the positioning of the incision arc in the y direction and the perpendicularity of the axis line have a significant impact on the stiffness of the flexible hinge. The errors in the positioning of the incision arc in the x direction have a smaller influence. Based on these findings, it is recommended to strictly control the positioning errors in the y direction and the perpendicularity of the axis line, while also considering reducing the value of t/R to minimize the impact of positioning errors in the x direction.
In conclusion, this research provides a comprehensive analysis of the machining errors in straight circular flexible hinges and their impact on stiffness. The derived stiffness calculation formulas and the validation using finite element analysis contribute to the understanding of hinge parameter design and processing. Further research can be conducted to explore other types of machining errors and their effects on the performance of flexible hinges.
Abstract:
The car door gap is a common source of electromagnetic interference in cars. In this study, we propose a simplified model of a car door and its attached cavity by analyzing the structure of the car door gap and related accessories. We then establish a model based on the size parameters of the front door of a sedan in HFSS software and conduct a simulation calculation. The shielding effectiveness of the electromagnetic field is investigated by gradually increasing the span of the door hinge, taking into account the mechanics, vibration, and noise in door design. The results show that the change in the hinge span has little effect on the shielding effectiveness below 650MHz, but has a significant impact above 650MHz. This research provides a reference method for improving automotive electromagnetic compatibility performance.
Modern automobiles use a large number of electronic devices to meet the requirements of safety, environmental protection, comfort, and energy saving. The cost of electronic components in domestically produced cars has accounted for 20% to 30% of the total cost of the vehicle. However, automotive electronic equipment also brings electromagnetic radiation interference, which can interfere with receiver equipment outside the vehicle and affect the normal operation of automotive electronic equipment. Shielding is a common method to improve the electromagnetic compatibility performance of electronic equipment. The car door gap provides a path for external electromagnetic radiation interference to enter the car and for electromagnetic radiation inside the car to leak outside through the door. The presence of hinges and door locks also affects the electromagnetic shielding effectiveness of the door. Therefore, it is important to study the influence of door hinges and door locks on the electromagnetic coupling characteristics of the gap.
Model Simplification of a Car Door:
The structure of a car door includes hinges and a door lock. A simplified model of the car door is established, considering the size parameters of the front door of a sedan. The gap structure of the simplified model is a stepped structure with right angles. The gap is filled with sealing rubber strips. The width of each part of the gap is set to 3mm for efficiency, and the inner wall of the gap is considered as an air cavity. The window part of the simplified model is filled with an ideal conductor with the same thickness as the window glass.
Simulation Model Establishment of Electromagnetic Shielding for Car Door Gap:
The simulation model of the car door gap is established using HFSS software, which is based on the finite element method (FEM) of electromagnetic field analysis. The model is discretized into tetrahedral elements, and high-order polynomial interpolation is used for accuracy. The simulation model includes the geometry of the car door and
In recent years, many customers have reported difficulties in purchasing aluminum frame hinges from the market. The main reason behind this issue is the rapid rise in the price of alloy materials since 2005. The cost has increased from more than 10,000 yuan to over 30,000 yuan. This significant price hike has raised concerns among manufacturers who fear potential losses if the price of raw materials declines after the production of aluminum frame hinges.
Currently, although the material cost of aluminum frame hinges is relatively stable, the price remains high. Furthermore, the demand for these hinges isn't very large, which leads many manufacturers to opt out of producing them. However, despite the challenges faced by manufacturers, aluminum frame hinges offer several impressive characteristics that make them highly desirable for customers.
Firstly, these hinges come equipped with a self-closing system and built-in damper, ensuring that cabinet doors can be closed silently. The inclusion of this feature not only protects the furniture but also enhances its lifespan. Additionally, the hinge cup is a fully automatic one-time stamping and forming hinge accessory. This means that both the appearance and functionality of the hinge are satisfactory. The use of a six-piece spring chain rod and a hinge body material thickness of 1.1MM further strengthen the hinge's performance. Even when burdened with a 20 kg load-bearing cabinet door, the hinge operates effortlessly, eliminating the risk of easy falls and damages that are commonly associated with general hinges.
Another noteworthy characteristic of these hinges is the perfect hydraulic damping system with which they are equipped. This system creates resistance when the cabinet door is being closed, allowing it to be tightly sealed by spring tension. As a result, the cabinet door no longer makes the annoying ping-pong sound when closing, but instead smoothly and silently adds to the harmony of the living space. This feature is especially beneficial for individuals living in noisy environments, as it helps create a quiet and peaceful atmosphere in their homes.
