摘要

車輛懸吊系統主要功能為吸收車輛通過不平整路面時的震動能量，目前的設計均以被動式阻尼器吸收路面產生的震動能量。由於路面震動隨著車輛行駛持續產生，若能將此震動能量以電能方式儲存，則不但能控制整車書是性能，更能提高能源使用率。本研究主要設計一種能量回收型半主動式避震系統，將原有阻尼器以發電機產生取代，以產生電能並儲存，同時藉由控制發電電流，以提供懸吊系統不同的阻尼力，達到半主動式懸吊系統的功能。此懸吊系統較適合用於在崎嶇路面行駛之載具，如越野車，農用車或工程用車輛等。
本研究首先設計該系統之機械與控制結構，然後探討車輛於不同車速，行駛於不同粗糙度路面時，整車之乘適性、操控性以及所產生的電能，以進行參數最佳化設計。而評估的性能指標為車體加速度與輪胎變形量、發電能量，以及懸吊發電系統之限制。
數值模擬結果顯示，本研究所設計的懸吊系統與傳統液壓筒式相比，在乘適性與操控性的表現皆較佳，並且能將能量回收至電瓶中儲存。

The main function of vehicle suspension system is to absorb the vibration energy from uneven roads. This thesis is focused on energy recovery suspension system (ERSS) that is expected to control the damping force of the system while transform the kinetic energy into electric energy. In contrast to traditional design with a hydraulic damper, the proposed ERSS adopts a rotary-type electric generator as the damper. By controlling the generating current, the generator not only offers an adequate amount of damping force to the suspension system, but also transforms the kinetic energy into electric energy. The purpose of this thesis is to develop a design and evaluation procedure for the ERSS, under constrains of mechanical working space and characteristics of the generator. From the numerical simulation results, the design system can achieve high performance in terms of vehicle body acceleration, tire deformation, and recovery electric energy.
