A Review of Scientific Instruments

Mechatronics Technology is a growing career field that deals with the integration of mechanical and electronic components managed by control systems. Mechatronics technicians troubleshoot, maintain and repair mechanical equipment controlled by electrical, electronic and computer systems. These types of systems are increasingly used in a wide variety of manufacturing and industrial settings. Clark College's Mechatronics Technology (MTX) classes emphasize current concepts and technology by providing practical, hands-on experiences with the latest, industry standard equipment. In addition to the technical knowhow needed to maintain and repair equipment, the certificate and degree programs will help prepare students to think critically, function as a successful team member and communicate clearly too internal and external customers.

Design and Performance Analysis of a Sub-micron Piezoelectric Flexible Micro Drive System

Measurement results of the output stepping rotary angle of a piezoelectric-driven rotary actuator by means of inchworm motion have been compared with results obtained from three-dimensional Finite Element Analysis (FEA). Comparison results showed a good quantitative agreement, and confirmed the validity and accuracy of the finite element method in the design and analysis of the inchworm-type rotary actuators. In addition, the effect of the gap between the stator and rotor on the working performance of the actuator was investigated by using FEA. With the increase of the gap, both the stepping rotary angle and the output torque of the rotor decrease significantly. Therefore, this factor must be taken into consideration in the design and machining of this kind of actuators.
