The equations used in our thrust block calculator can be found in nearly any college level fluid mechanics textbook (e.g. Munson et al., 1998) or fluid mechanics reference handbook. The force equations are based on linear momentum conservation. P2 is computed using the Bernoulli Equation, which...
More complex mechanisms with four or more blocks are described by systems with equations of higher degrees which do not have an analytical solution in the form of roots. A semi-analytical solution is also given for locating the point of application of the active thrust....

Three different failure mechanisms of the thrust wedge are examined, called, respectively, Mechanism 1 (with the thrust wedge formed by a single block), Mechanism 2 (where the thrust wedge is composed of two rigid blocks, one slipping with respect to the other) and Mechanism 3 (which ...

Figure 4. Block diagram of PPMLM direct thrust force control system based on IESO−CFDL−MFAPC. The internal and external disturbance produced in the system is called the total disturbance 𝑓f of the system; 𝑓f is a nonlinear equation formed by the unknown disturbance of the system,...
Equations (3) and (4) describe the operation of the known crank mechanism. However, in this example (Figure 4), the crank position is fixed at a given rotation angle 𝛾𝑐1γc1, and then the center “C” after such angle fixation can move along the axis 𝑋𝑎Xa. The mechanical ...
The static model will include two equations of equality of the flow rate Qp through the elastic orifice and Qk through the damping annular diaphragms, the flow rates Qk and Qh at the entrance to the bearing layer of the dimensionless thickness H, as well as the equation of force equilibrium...
Motivated by these considerations, this study aims to propose a new analytical solution to solve the inverse kinematics of shield thrust mechanism, in which all equations are explicit equations, and all the parameters are easy to determine. Based on the proposed model, the displacement, velocity, ...
