A Crank Slider Mechanism Is Shown In Figure 1 Perform Kinetostatic Analysis For The Mechanism The Crank Is Running At 1 (118.43 KiB) Viewed 33 times
A crank-slider mechanism is shown in Figure 1. Perform kinetostatic analysis for the mechanism. The crank is running at 3600 rpm (constant speed) CCW. The stroke is 76 mm. L/R = 3.5 (L: length of the coupler, R: length of the crank), m2 = 5 kg, m3 = ( 0.5 kg, m4 = 0.3 kg, rG2 = 0.3R, rG3 = 0.36L, IG2 = 0.05 kg m2, IG3 = 0.002 kg m2. Ignore friction. The gas force is shown as the black curve in Figure 2. 1) Determine L and R according to the required stroke. 2) Consider the gas force only, determine the corresponding shaking force, the shaking moment based on the point O, and the output torque T2. 3) Consider the inertial force only, determine the corresponding shaking force, the shaking moment based on the point O, and the output torque T2.
