The invention discloses a link mechanism experimental device with outputted parameter regulating and controlling functions and a method for regulating and controlling outputted parameters, and belongs to the field of transmission technologies for link mechanisms. The link mechanism experimental device and the method have the advantages that the link mechanism experimental device and the method are mainly used for displaying classroom teaching experiments and designing and optimizing mechanical structures during practical application; variable rotational speeds and variable link lengths can be inputted into motors, the rotational speeds of active components and the link lengths of units with variable link lengths can be changed in real time in link mechanism running procedures, and accordingly functions which cannot be implemented by certain traditional link mechanisms can be implemented; the possible problem that speeds and acceleration of designed link mechanisms exceed safety threshold values can be solved by the aid of the method, the problem that outputted parameters of the designed link mechanisms are not completely fit with required outputted parameters further can be solved, accordingly, application of the link mechanisms is free of constraints of fixed link lengths and fixed rotational speeds, and the application ranges of the link mechanisms can be expanded; the link mechanism experimental device and the method with solving ideas not only can be applied to classroom teaching experiments, but also can be applied to actual production.
