Abstract
A dynamic analysis of a tilting actuator for a projection TV is presented in this study. Severe vibration of a tilting actuator deteriorates the video quality of a projection TV. For this reason, a dynamic analysis of the tilting actuator system is essential to improve the video quality. The dynamic behaviors of the mirror reactive-type tilting actuator are examined in order to obtain design requirements of the lens transmissive-type tilting actuator. Based on these design requirements, a basic design is performed for the lens transmissive-type tilting actuator. With the basic design, the dynamic characteristics of the lens transmissive-type actuator are investigated by the finite element analysis After the prototype of the actuator is manufactured, the dynamic behaviors of the prototype are examined by experiments. As a result of this study, a new design for the hinge configuration of the actuator is suggested for better performance.
