6 FAQs about [Energy storage preload hinge]
What is a compliant hinge?
A compliant hinge providing 90 degrees of rotation was recently developed as a potential hinge for deployable booms on spacecraft and compliant elements have been pro-posed for use in deploying booms . Compliant mechanisms can achieve bistable motion without bearings or friction. They can be designed to provide precise state positions.
What is the difference between a rigid hinge and a passive drive?
The passive drive is generally a form of spring self-storage drive, a flat spiral spring and cylindrical helical torsional springs, which are commonly used ones. 1, 2, 10, 11 A rigid hinge generally has a self-locking mechanism, and an appropriate design of a self-locking mechanism and shafting contribute to high stiffness and precision.
Is a hinged boom a linear deployable mechanism?
Therefore, a hinged boom with rigid hinges is still the mainstream of linear deployable mechanism. The spring-driven rigid hinge is widely employed in one-time deployments due to its simple structure, light weight, easy installation and high reliability.
Why is the stiffness of the cable drive lower than the hinges?
In the stiffness analysis of the boom, due to ductility of the cable, the stiffness of the cable drive is much lower than that of the hinges.
How does preload FPI work?
At the initial state, preload Fpi is applied at point A of the cable wheel. Due to the friction between cable and wheels, the relation of the tensions in different sections of the cable is FAC > FCD > FDF. During the deployment of the boom, the tension FAC in section AC decreases, and the tensions FCD and FDF in section CD and DF increase slightly.
What is K preload coefficient?
k is a preload coefficient which is used to express the ratio of the initial preload Fpi to the target preload Fp. Taking the preload of the cable drive between the root hinge and the mid-boom hinge as an example, and relevant parameters are shown in Table 3.
