Applications of dynamics metamodels of an eccentric crank-slider mechanism in the initial phase of their design

The concept of dynamics metamodels to predict the behavior of an eccentric crank-slider mechanism is presented. The mathematical model of the system is elaborated using the formalism of joint coordinates, homogeneous transformations matrices, and Lagrange equations of the second kind. The flexibility of the drive and links, friction in joints, and external impact on the slider, for example, in the form of a bumper, are considered in the proposed model. The appropriate indicators are introduced to assess the mentioned phenomena based on the values of the kinetic energy of the slider and driving torque.
