  2. Constraint (computer-aided design) - Wikipedia

    en.wikipedia.org/wiki/Constraint_(computer-aided...

    The shaft and pulleys share a common centerline. The constraints of the key are set in relation to the keyseat. A constraint in computer-aided design (CAD) software is a limitation or restriction imposed by a designer or an engineer upon geometric properties [1]: 203 of an entity of a design model (i.e. sketch) that maintains its structure as the model is manipulated.

  3. Unilateral contact - Wikipedia

    en.wikipedia.org/wiki/Unilateral_contact

    There are mainly two kinds of methods to model the unilateral constraints. The first kind is based on smooth contact dynamics, including methods using Hertz's models, penalty methods, and some regularization force models, while the second kind is based on the non-smooth contact dynamics, which models the system with unilateral contacts as variational inequalities.

  4. Constraint - Wikipedia

    en.wikipedia.org/wiki/Constraint

    Constraint may refer to: . Constraint (computer-aided design), a demarcation of geometrical characteristics between two or more entities or solid modeling bodies Constraint (mathematics), a condition of an optimization problem that the solution must satisfy

  5. Degrees of freedom (mechanics) - Wikipedia

    en.wikipedia.org/wiki/Degrees_of_freedom_(mechanics)

    Joints that connect bodies in this system remove degrees of freedom and reduce mobility. Specifically, hinges and sliders each impose five constraints and therefore remove five degrees of freedom. It is convenient to define the number of constraints c that a joint imposes in terms of the joint's freedom f, where c = 6 − f.

  7. Overconstrained mechanism - Wikipedia

    en.wikipedia.org/wiki/Overconstrained_mechanism

    In mechanical engineering, an overconstrained mechanism is a linkage that has more degrees of freedom than is predicted by the mobility formula. The mobility formula evaluates the degree of freedom of a system of rigid bodies that results when constraints are imposed in the form of joints between the links.

  9. Multidisciplinary design optimization - Wikipedia

    en.wikipedia.org/wiki/Multidisciplinary_design...

    A constraint is a condition that must be satisfied in order for the design to be feasible. An example of a constraint in aircraft design is that the lift generated by a wing must be equal to the weight of the aircraft. In addition to physical laws, constraints can reflect resource limitations, user requirements, or bounds on the validity of the ...
