Tolerances in Geometric Constraint Problems
نویسندگان
چکیده
We study error propagation through implicit geometric problems by linearizing and estimating the linearization error. The method is particularly useful for quadratic constraints, which turns out to be no big restriction for many geometric problems in applications.

An investigation the effects of geometric tolerances on the natural frequencies of rotating shafts
This paper examines the effects of geometric tolerances on the natural frequencies of rotating shafts. In order to model the tolerances, a code is written in MATLAB 2013 that produces deviated points. Deviated points are controlled by different geometric tolerances, including cylindricity, total run-out and coaxiality tolerances. Final surfaces and models passing through the points are created ...
متن کاملMulti-item inventory model with probabilistic demand function under permissible delay in payment and fuzzy-stochastic budget constraint: A signomial geometric programming method
This study proposes a new multi-item inventory model with hybrid cost parameters under a fuzzy-stochastic constraint and permissible delay in payment. The price and marketing expenditure dependent stochastic demand and the demand dependent the unit production cost are considered. Shortages are allowed and partially backordered. The main objective of this paper is to determine selling price, mar...
متن کاملOperations on polytopes: application to tolerance analysis
This article presents numerical methods in order to solve problems of tolerance analysis. A geometric specification, a contact specification and a functional requirement can be respectively characterized by a finite set of geometric constraints, a finite set of contact constraints and a finite set of functional constraints. Mathematically each constraint formalises a n-face (hyperplan of dimens...
متن کاملGeometric Constraint Problems and Solution Instances
Geometric constraint solving is a growing field devoted to solve geometric problems defined by relationships, called constraints, established between the geometric elements. In this work we show that what characterizes a geometric constraint problem is the set of geometric elements on which the problem is defined. If the problem is wellconstrained, a given solution instance to the geometric con...
متن کاملSolving Space Planning Problems Using Constraint Technology
Constraint programming techniques have proven their eeciency in solving high combinatory problems. In this paper, we study the adaptation , the extension and the limits of those techniques in the space planning problem which consists in nding the locations and the sizes of several objects under geometric constraints in a location space. For all that, we deene the formalism of Geometric Constrai...
