The construction and performance of various flexure hinges
Journal of Scientific Instruments, 1962The first part of the paper describes a simple and yet precise clamp for strip hinges which facilitates the construction of flexure hinges. The use of this clamping system in various flexure hinges is described and it is believed that it is of fairly general application. The second part of the paper discusses the merits of the single strip hinge, which

The performance comparison of typical notched flexure hinges
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2019Flexure hinges, which serve as the crucial joints in a large number of compliant mechanisms, have been widely applied in a variety of significant fields where there is high demand for the micro/nano motions with high resolution and high precision. Currently, an increasing number of notched flexure hinges with different structures and performances have ...

An experimental study on the flexural performance of laminated glass
Structural Engineering and Mechanics, 2014This paper reported an experimental study on creep behaviors of PVB and Ionoplast laminated glass (LG) under load duration of 30 days. The tests were carried out in room temperature (23°C). The study revealed that after sustaining loads for 30 days, the mid-span deflection of PVB LG increased by almost 102% compared with its short term deflection ...

Accuracy Performances of Asymmetrical Right Circular Flexure Hinge
2011Flexure hinge has been widely used in high precision micro-positioning mechanism driven by piezoelectric ceramic and the most common type is right circular flexure hinge. According to the size of the cutting arc radius of both sides of right circular flexure hinge, the structure coefficient is introduced and asymmetrical right circular flexure hinges ...

CTA #30. Flexural Bond Performance
1975Investigates the development of flexural bond in short span hollow-core slabs under ultimate flexural loads. A simple criterion is proposed, on the basis of 32 tests, for assurance that the units will achieve or exceed the limiting steel tension specified by ACT 318-71.

Flexure mounts for high-performance astronomical lenses
SPIE Proceedings, 2006We have developed practical, high performance flexure mounts for large astronomical lenses in the Binospec spectrograph. Flexure mounts are an attractive alternative to the widely used elastomeric lens mounts when high axial stiffness is a priority and coupling fluids are incompatible with elastomers.

The performance of a linear compressor with triangle flexure bearings
AIP Conference Proceedings, 2012This paper reports the performance of a self-fabricated moving coil linear compressor at Zhejiang University. The efficiency of this compressor is tested by an RC load method. From experimental results, its resonant frequency is below 30Hz. When combined with a pulse tube cryocooler (PTC) working at 40Hz, the minimum temperature is 49.1K; the cooling ...

Performance of small arrays of flexural disk transducers
The Journal of the Acoustical Society of America, 1976Trilaminar disk elements of small aperture (a = 34 mm) have been used in compact four- and six-element arrays for 2.4-kHz resonant frequency projectors with improved performance over single balanced pair (two-element) projectors of larger (a = 54 mm) elemental aperture.

Testing Passive Components for Flexure Crack Performance
SMTA International, 2007ABSTRACT Surface mount capacitors are used extensively in harsh automotive applications. In addition, the assembly processes for manufacturing the electronic systems can often lead to high stress on the crack-sensitive passive components. The typical mode of failure is a flex crack, which can often leads to a “short” failure.
