Fourbar synthesizes and analyzes any fourbar, pin-jointed linkage. Kinematics and dynamics of cam-driven fourbar and sixbar linkages with or without sliders.

Interactive Four-Bar Linkage Dynamic Force Analysis Given position, velocity, acceleration, and inertia properties such as mass and mass moment of inertia for each moving link of a four-bar linkage, we are able to perform force analysis for the linkage. Three static equilibrium equations, in terms of forces in the X and Y directions and moment about the center of gravity of the link, can be written for each link. The is also available. For link 2, we get F12x + F32x + Fg2x = 0 (1) -m2g + F12y + F32y + Fg2y = 0 (2) Ts + (-rg2) x F12 + (r2-rg2) x F32 + Tg2 = 0 (3) where rg2=rg2*exp(i(theta2+delta2)) is the position vector from joint Ao to the center of gravity of link 2. F12 and F32 are the joint forces acting on link 2.

Fg2 and Tg2 are the inertia force and inertia moment of link 2. M2 is the mass of link 2 and Ts is the driving torque. For link 3 we get F23x + F43x + Fg3x = 0 (4) -m3g + F23y + F43y + Fg3y = 0 (5) (-rg3) x F23 + (r3-rg3) x F43 + Tg3 = 0 (6) where rg3 = rg3*exp(i(theta3+delta3)) is the position vector from joint A to the center of gravity of link 3. F23 and F43 are the joint forces acting on link 3. Fg3 and Tg3 are the inertia force and inertia moment of link 3. M3 is the mass of link 3.

For link 4 we get F34x + F14x + Fg4x = 0 (7) -m4g + F34y + F14y + Fg4y = 0 (8) (-rg4) x F14 + (r4-rg4) x F34 + Tg4 + Tl = 0 (9) where rg4=rg4*exp(i(theta4+delta4)) is the position vector from joint Bo to the center of gravity of link 4. F14 and F34 are the joint forces acting on link 4. Fg4 and Tg4 are the inertia force and inertia moment of link 4.

M4 is the mass of link 4 and Tl is the torque of external load.

The Matlab and Working Model files can be used to perform the position, velocity, and acceleration analyses of a four-bar linkage and to check Homework Problems 4.6, 4.7, 6.4, 6.6, 7.3, and 7.4 of the textbook. All parameters are defined in Figures P4.1, P6.1, and P7.1 respectively. To change the dimensions of the Working Model file, simply drag the slider control to change the link length or the orientation angle. If the link length is beyond the maximum/minimum of the slider range, adjust the range in the property table.
