A study on tolerance design of machine tool components based on shape generation motions

open access: yesNihon Kikai Gakkai ronbunshu, 2016
The kinematic motion deviations of the five-axis machining centers are deeply influenced by the geometric deviations of the components, such as guide-ways and bearings.

3D SOI edge coupler design for high tolerance

open access: yesAIP Advances, 2023
We designed and manufactured two single-mode fiber-to-chip three-dimensional (3D) edge couplers with taper and semi-cone structures on a 3.5 µm silicon device layer of a silicon-on-insulator.

Numerical Study on Design Approaches for Reduction of Float and Elimination of Over-constraints in Hole-pin Pattern Assembly [PDF]

open access: yes한국정밀공학회지
This paper addresses the issue of over-constrained assembly in mechanical designs using hole-pin patterns. When two hole-pin pairs are used, they can cause interference between components, leading to assembly failures.

Multiobjective Optimization Design of Truss Antenna

open access: yesInternational Journal of Aerospace Engineering, 2022
During the design and manufacturing process of the truss antenna, the surface accuracy of the truss antenna is inherently affected by tolerance. An appropriate optimal design of the truss antenna structure is important to improve surface accuracy.

Design of fault-tolerant computers [PDF]

open access: yesProceedings of the November 14-16, 1967, fall joint computer conference on - AFIPS '67 (Fall), 1967
Reliable performance of hardware has been a requirement for digital systems since the construction of the first digital computer. Improper functioning of the logic circuits in a digital system is manifested by logic faults, which are defined for this paper as "permanent or transient deviations of logic variables from the values specified in design."

Fault tolerant design for autonomous vehicle [PDF]

open access: yes2017 4th International Conference on Control, Decision and Information Technologies (CoDIT), 2017
A fault-tolerant control design strategy based upon sliding mode control and a descriptor observer for Upschitz system is presented. The aim is to mitigate the vehicle speed faults and provide accurate measurements for the control. Thus, the additive faults affecting the vehicle speed sensor are estimated, and accurate speed measurments are used to ...
