Research on Theoretical Basis of Design Optimization of Flexible Hinges and Flexible Body Mechanisms
Expanded
Flexible hinges have gained significant attention in precision devices due to their ability to transmit motion or energy through elastic deformation instead of rigid components. Compared to traditional motion hinges, flexible hinges offer advantages such as high motion resolution, no friction, no lubrication, and a simple manufacturing process. They have been widely used in various precision devices, including projection lithography objective lenses, silicon wafer workbenches, electronic scanning microscopes, space optical remote sensors, and precision and ultra-precision processing. The key parameters of compliant mechanisms, like flexible hinges, directly impact the dynamic characteristics and positioning accuracy of the end. Therefore, extensive research has been conducted to understand the flexibility of flexible hinges. This paper aims to study the flexibility matrix of straight beam rounded flexure hinges, analyze its parameters, and provide a theoretical basis for their design and optimization.
Flexibility Matrix of Straight Beam Rounded Flexure Hinges:
The straight beam rounded flexure hinge consists of a straight beam sheet structure with rounded corners at the hinge's ends to avoid stress concentration. The main geometric parameters include hinge height (h), hinge length (l), hinge thickness (t), and hinge fillet radius (r). To analyze the in-plane deformation of the hinge, an analytical calculation method based on the cantilever beam theory is derived. This method establishes a closed-loop analytical model for the in-plane flexibility matrix of the flexible hinge. Additionally, a simplified calculation formula for the flexibility matrix is provided when the ratio of hinge corner radius to thickness (r/t) is given.
Finite Element Verification:
To validate the derived analytical formula, a finite element model of the straight beam rounded flexure hinge is established using UGNX NASTRAN software. The simulation results of the finite element model are compared with the analytical values of the flexibility matrix parameters. The relative error between the two is analyzed for different variations in the hinge's structural parameters, such as the ratio of hinge length to thickness (l/t) and the ratio of hinge corner radius to thickness (r/t).
Results:
The analysis shows that for l/t ratios greater than or equal to 4, the relative error between the analytical and simulated values of the flexibility matrix is within 5.5%. However, for l/t ratios less than 4, the relative error is relatively large due to the inability to simplify the cantilever beam into a slender beam. This indicates that the closed-loop analytical model is more suitable for large l/t cases.
Regarding the ratio r/t, the analysis reveals that when 0.1 ≤ r/t ≤ 0.5, the relative error between the analytical and simulated values can be controlled within 9%. Additionally, when 0.2 ≤ r/t ≤ 0.3, the relative error can be controlled within 6.5%. These findings demonstrate the accuracy and applicability of the closed-loop analytical model for the flexibility matrix.
The closed-loop analytical model developed in this study provides a theoretical basis for the design and optimization of straight beam rounded flexure hinges. The analysis demonstrated that the model can accurately predict the flexibility matrix parameters when considering variations in hinge length, thickness, and corner radius. These findings will contribute to the advancement of compliant mechanisms and their applications in precision devices.

Why are FGV and hafele hinges selling better than Blum and Tallsen in the domestic market? _Industry
As we are all aware, Blum, Tallsen, FGV, and Hafele are widely recognized as distinguished hinge brands in the global market. Surprisingly, in China, FGV and Hafele hinges are considerably more prevalent, while Blum and Tallsen hinges are relatively scarce. Given that China holds the esteemed position of being the largest hinge producer worldwide, one cannot help but question the reasons behind these top hinge brands' inability to dominate the market in China. Are their prices exorbitant, making them difficult to sell? Does the technical expertise in the country lag behind, thereby impeding production capabilities? Or is there an alternate explanation for this intriguing phenomenon? In this comprehensive article, we will delve into these factors in greater detail and offer insightful analysis.
The Chinese market, especially in Guangdong province, has seen a significant presence of FGV and Hafele hinges. Guangdong is known as the largest hinge production base in China and its proximity to Hong Kong has influenced its market. Customary and habitual similarities between Guangdong and Hong Kong have led to the mirror-like hinge market in both regions. FGV hinges have been prevalent in Hong Kong for a long time, which has made their products highly accessible in the area. The popularity of FGV hinges can be attributed to their simplicity, cost-effectiveness, and reliability, which has won over many users.
Guangdong, being at the forefront of China's reform and opening-up policies, is the perfect location for B-side buyers looking to purchase and expand FGV hinges. In addition to this, FGV also has a foundry conveniently based in Guangdong, providing an ideal environment for its growth within the province. Despite entering the market later than FGV, Hafele has successfully gained a significant presence in Guangdong. This can be attributed to the similarities in structure and production processes between Hafele and FGV hinges, resulting in reduced costs and production complications. Additionally, Hafele hinges stand out due to their simple structure, convenience, and reliable quality, further strengthening their popularity in the region.
On the other hand, the limited presence of Blum and Tallsen hinges in Guangdong can be attributed to several significant factors. Firstly, these brands were introduced relatively late to the market, allowing FGV and Hafele hinges to establish a substantial foothold in the minds of consumers. Consequently, consumers naturally gravitate towards the familiar and trusted brands they have become accustomed to over time. Secondly, the structural differences between Blum and Tallsen hinges compared to FGV and Hafele hinges have posed as a significant obstacle. The manufacturing process for these hinges necessitates the utilization of advanced technology and substantial investments in mold creation, thereby significantly driving up the overall cost. In turn, the higher input costs and the frequent need for mold replacement have severely hindered the expansion of Blum and Tallsen hinges in Guangdong, further impeding their presence in the market.
In conclusion, the remarkable prevalence of FGV and Hafele hinges in the Chinese market, particularly in Guangdong province, can be primarily attributed to a multitude of influential factors. The exceptional proximity to Hong Kong, along with the presence of FGV's offices in the region, have undeniably bolstered their popularity among consumers. Furthermore, the unparalleled simplicity, cost-effectiveness, and unwavering quality assurance of FGV hinges have firmly solidified them as the preferred choice among discerning buyers. Similarly, Hafele hinges have gained remarkable traction in the market, owing to their striking resemblance to FGV hinges in terms of structure, production processes, and overall cost-efficiency. This remarkable similarity has greatly enhanced their appeal to consumers seeking a comparable alternative. Conversely, the expansion of both Blum and Tallsen hinges in Guangdong has been notably impeded by various factors. Their late introduction into the market has placed them at a disadvantage, as consumers have already gravitated towards the reliability and familiarity of FGV and Hafele hinges. Additionally, structural differences and higher input costs have further hindered the prospects of Blum and Tallsen hinges in this highly competitive market. Ultimately, the unparalleled success of FGV and Hafele hinges in Guangdong can be attributed to a combination of their attractive qualities, strategic positioning, and consumer preferences. As the market continues to evolve, it will be crucial for companies such as Blum and Tallsen to address these challenges in order to effectively penetrate and establish a foothold in this promising region.
