A flexure pivot, utilized in place of bearings for their frictionless properties in precision alignment mechanisms and scientific instruments. A flexure bearing is a category of flexure which is engineered to be compliant in one or more angular degrees of freedom. Flexure bearings are often part of compliant mechanisms. Flexure bearings serve ...
A flexure pivot, utilized in place of bearings for its frictionless adjustment properties. A living hinge (a type of flexure), on the lid of a Tic Tac box. This hinge has one compliant degree of freedom. A flexure is a flexible element (or combination of elements) engineered to be compliant in specific degrees of freedom. [1]
[citation needed] Other optimization techniques focus topology optimization of the flexure joints by taking as input a rigid mechanism and replacing all the rigid joints with optimized flexure joints. [4] To predict the behavior of the structure, finite-element stress analysis is done to find deformation and stresses over the entire structure.
A ball bearing. A bearing is a machine element that constrains relative motion to only the desired motion and reduces friction between moving parts.The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent a motion by controlling the vectors of normal forces that bear on the moving parts.
The geometry of the way can vary depending on the situation. The most common types are flat, vee, and dovetail ways. Flat ways are used when there is little requirement for the slide to be constrained perpendicular to the axis of movement, or the constraint is being provided by another component or otherwise not needed, such as on the carriage of a lathe.
The rangekeeper performed a linear extrapolation of the target range and bearing as a function of time based on the target information samples. In addition to ship-board target observations, rangekeepers could also take input from spotting aircraft or even manned balloons tethered to the own ship. These spotting platforms could be launched and ...
Zaber motorized linear stage. A linear stage or translation stage is a component of a precise motion system used to restrict an object to a single axis of motion. The term linear slide is often used interchangeably with "linear stage", though technically "linear slide" refers to a linear motion bearing, which is only a component of a linear stage.
FACT combines principles of screw theory, linear algebra, projective geometry, and exact-constraint design. The methodology employs a library of vector spaces derived from these principles and represented by geometric shapes. These shapes are categorized into freedom spaces, constraint spaces, and actuation spaces, each serving a unique purpose ...
