Q6. Two strips of PZT are bonded to form a bimorph actuator shown in the figure below. The bimorph has a small mass at the free end. OV Mass, m Supply OV Each actuator has the following specifications: Dimensions: length = 50 mm, width = 5 mm, thickness = 0.5 mm d13-133x10-12 m/V, d33 = 500x10-¹² m/V PZT charge constant: PZT Young's Modulus: Available voltage source: E = 70×109 N/m² ±200 V (Assume ideal actuator characteristics.) • With no electrical connections to the bimorph, the mass vibrates freely at 63.66 Hz when disturbed. What is the value of the mass, m? • By applying a voltage to the supply as shown, the mass can be raised and lowered. Find the full range of motion available. ● Find the voltage required to maintain zero deflection with the weight added.
