This Ph.D. thesis presents the design, modeling, optimization, prototyping, and experimental methodologies for a novel actuation system for the synchronized segmentally interchanging pulley transmission system (SSIPTS). The SSIPTS is an improved transmission which offers the combined benefits of existing transmission systems for the automotive, the power generation, and the heating, ventilation, and air conditioning (HVAC) industries.
As a major subsystem of the SSIPTS, the Pulley Segment Actuation System (PSAS) plays a critical role in the SSIPTS operation and success. However, the overall design of the SSIPTS and its operation principle introduce very challenging and conflicting design requirements for PSASs that the existing actuation technologies cannot meet. To address the lack of actuation technologies for the PSAS application, this research proposes a unique actuation system that meets all the challenging design requirements of the PSAS. This new actuation system is based on the electromagnetic moving coil actuator (MCA) technology. The proposed system is conceptualized and modeled. The key parameters of the actuation system are defined following the conceptual design and modeling. Further, the geometry mapping optimization and the FEM analysis are conducted to determine the optimized values for the key design parameters. From the simulation results, the optimized actuator is shaped. Moreover, a proper control strategy is proposed for the motion of the actuator. Experiments are performed to find the empirical parameters of the actuator, to validate the proposed design, and to test the performance of the actuator. Experimental results show that the prototype of the actuation system meets the design requirements and is feasible for implementation in the SSIPTS.
The main contribution of this thesis is to develop a highly efficient and reliable ultra fast bi-stable actuation system for the PSAS for the SSIPTS. As an ultra fast bistable actuation system, the designed actuation system has many advantages over other types of actuation systems: higher load capacity, smaller dimensions, and good controllability. These performance characteristics make the designed actuation system an excellent candidate in applications requiring fast transient response, high precision, and high load capacity such as electromagnetic valve actuators for engines, high speed pick and place, and precise positioning.
