2.2 Constrained – Unconstrained Mechanism<\/strong><\/h1>\n

“Constrained mechanism”<\/strong><\/span> may mean two different things in mechanisms literature.<\/p>\n

    \n
  1. It may refer to mechanisms in which F = 1.<\/li>\n
  2. It may refer to mechanisms whose degree-of-freedom may be greater or equal to one, but the number of inputs (the number of independent parameters) defined is equal to the degree-of freedom.<\/li>\n<\/ol>\n

    With Unconstrained mechanisms<\/span><\/strong> we mean those mechanisms with more than one degree-of-freedom and the number of inputs defined is less than the degree-of-freedom of the mechanism, but the motion is constrained by the forces and dynamic characteristics of the system. A good example is the differential of a car where the rotation of the wheels is governed by the moment acting on them. Due to these characteristics, when taking a turn, the inner wheel rotates less than the outer wheel. This unconstrained motion will create problems in icy conditions.<\/p>\n

    \"\"<\/p>\n

    Above, two other examples for unconstrained mechanisms are given. One of the freedoms of the mechanism is usually controlled by a continuous motion. The other freedom is usually controlled by a spring and a key (not shown in the above examples). The motion is governed by both the continuous input plus the force or moment acting on the links under the spring force.<\/p>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div>\n\n\n
