The block allows you to simulate mechanisms in which the fastening planes of the hinges C1 and C 2 are parallel or perpendicular (fastening to a vertical plane). The figure (Figure 1) shows a mechanism with a parallel arrangement of the hinge attachment planes. In case of arbitrary arrangement of the hinge attachment planes, this should be taken into account when determining the angle α.
The block allows you to set the reference directions of the angle and the linear position of the slider: if the rotary and translatory motion go on "in one direction", then the increase in the angle at the port "C1" (angle φ1) will correspond to the increase in the linear position at the port "S". The figure (Figure 1) shows a mechanism with the motion "in different directions", since an increase in the angle φ1 corresponds to a decrease in the position S.
- ω – angular speed of the port "C", rad/s
- v – linear speed at the port "S", m/s
- ε – angular acceleration at the port "C", rad/s2
- a – linear acceleration at the port "S", m/s2
- T – torque supplied to the port "C", Nm
- F – force applied to the port "S", N
- K – coupling coefficient, m
- dir – value indicating the matching of the reference directions of the angle φ1 and the linear position S, has a value of 1 or -1
- R – distance between the hinges (Figure 1), m
- α – angle between the bodies, rad. As a rule, it is determined by the difference between the angles φ1 and φ2 (Figure 1)
The block defines the torque T and the force F by solving the coupling equation.
