  • holonomic 与 nonholonomic 的本质区别是什么？ - 知乎
    本文部分参考了目前在加州大学河滨分校任教的Flip Tanedo教授在康奈尔大学读PhD的时候写的Notes on non-holonomic constraints以及CMU大牛教授Matthew T Mason教的mechanics of Manipulation课的Lec5-Nonholonomic constraint。
  • classical mechanics - What are holonomic and non-holonomic constraints . . .
    Non-holonomic constraints are basically just all other cases: when the constraints cannot be written as an equation between coordinates (but often as an inequality) An example of a system with non-holonomic constraints is a particle trapped in a spherical shell In three spatial dimensions, the particle then has 3 degrees of freedom
  • Non-Holonomic constraints - Physics Stack Exchange
    @Eli has shown how this is a holonomic constraint mathematically However, there might be concerns about the periodicity of the generalized coordinates and the configuration In this question, we are only looking at the constraints without considering the dynamics, so gravity is ignored as usual
  • classical mechanics - Holonomic and non-holonomic constraints - Physics . . .
    If we now impose further [e g non-holonomic$^\dagger$] constraints, the generalized coordinates $(q^1, \ldots, q^n)$ wont be completely independent anymore $^\dagger$ Semiholonomic constraints can be implemented with the help of Lagrange multipliers , cf e g my Phys SE answer here
  • Lagrange equations for non-holonomic monogenic system
    Goldstein is talking about semi-holonomic constraints; not general non-holonomic constraints, such as, e g inequalities Goldstein's treatment of semi-holonomic constraints via a stationary action principle has already been criticize in e g Ref 3 and this this related Phys SE posts
  • Definition classification of holonomic and non-holonomic constraints
    Ref 1 defines a non-holonomic constraint as the opposite of a holonomic constraint Ref 1 mentions that inequalities (aka one-sided constraints) are examples of non-holonomic constraints For completeness, let us also mention semi-holonomic constraints References: H Goldstein, Classical Mechanics; Section 1 3
  • Why is this a non-holonomic constraint? - Physics Stack Exchange
    For example, the motion of a particle constrained to lie on the surface of a sphere is subject to a holonomic constraint, but if the particle is able to fall off the sphere under the influence of gravity, the constraint becomes non-holonomic
  • 如何判断完整性约束移动机器人？ - 知乎
    而Non-holonomic 非完整性约束是指 可控自由度小于机器人总自由度。通常地面机器人的自由度为3，包括x,y与朝向。对于角轮（castor wheels）或者是全向轮（Omni-wheels）的机器人，是holonomic的，因为它能够朝各个方向移动，并且机器人总自由度与可控
  • classical mechanics - Non-holonomic generalised forces of constraint . . .
    OP's starts with the correct non-variational Lagrange equations (1) for affine non-holonomic constraints (=semi-holonomic constraints) It should be stressed that the attempt in Ref 1 to construct a variational formulation for non-holonomic constraints is flawed and has been retracted, cf this Phys SE post
  • Can the Lagrange multiplier method be used with non-holonomic constraints?
    On one hand, it is possible to use d'Alembert's variational principle to incorporate semi-holonomic constraints (1) into the Lagrange equations with the use of Lagrange multipliers $\lambda^1,\ldots ,\lambda^m$, cf this Phys SE post
