動力夾頭幾何公差方面的一個關鍵乃是確定動力夾頭系統的夾緊力和接觸力，工件的變形是由夾緊力引起的。當夾緊力增加到最大極限以上時，會發生變形。但是，如果夾緊力降至最小極限以下，則可能會分離工件，從而導致嚴重的碰撞。動力夾頭的耐用性也是至關重要的因素，因為在夾持工件的過程中會發生損壞和碰撞。在確定零件是否可以承受應用的各種邊界條件時，應力起著關鍵作用。
這項研究代表三爪動力夾頭3H-06的動態特性評估。本文共分三個部分。在第一部分中，對三爪動力夾頭進行剛體分析，並分析無摩擦以及帶摩擦的工作條件下的夾緊力。在第二部分中，對三爪電動夾頭進行撓性體分析，並在不同的邊界條件下，使用FFlex，RFlex和RFlexGen體分析方法對鑄鐵和鋁材料的最大應力和最大變形進行分析。研究諸如懸臂樑和簡支梁邊界條件以及在不同載荷條件下的情況。在第三部分中，進行疲勞分析，並且確定鋼（MANTEN）材料的動力夾頭主鉗在不同負載條件下的損壞（最大）和壽命（最小）。本論文之研究載具為佳賀精機股份有限公司所設計的動力夾頭3H-06模型。該公司使用三維繪圖軟件（SolidWorks）設計動力夾頭模型。為了評估剛體分析和疲勞分析，則使用RecurDyn V9R2軟件。為了確定撓性機械零件分析，使用ANSYS Mechanical APDL 19.1和RecurDyn V9R2。仿真數據可以研究夾緊力，接觸力，最大應力和最大變形以及三爪動力夾頭系統的耐久性。

A key aspect in the geometric tolerances of power chuck is determining the clamping force and contact force of power chuck system. The deformation of the work piece is caused by the clamping force. Deformation occurs when the clamping force increases above the maximum limit. However, if the clamping force falls below the minimum limit, it is possible to detach the work piece, which can lead to severe crashes. The durability of the power chuck is also essential factor as damage and crashes occur in the process of holding the work piece. When deciding whether the part can withstand the various boundary conditions of the application, stress plays a key role. Stress also occurs when the work piece is held by 3 jaws. Stresses also depend on the material properties of the work piece.
This study represents the dynamic characteristic evaluation of the 3-jaw power chuck 3H-06. This thesis consists of three sections. In the first section, the rigid body analysis of 3-jaw power chuck was performed. The clamping force without friction and with friction conditions were analyzed. In the second section, the flexible body analysis of 3-jaw power chuck was performed. The Max.Stress and Max.Deformation of work piece for Cast iron and Aluminum materials using FFlex, RFlex and RFlexGen flexible body analysis methods under various boundary conditions such as cantilever beam and simple supported beam with different load conditions were investigated. In the third section, fatigue analysis was performed. The Damage (Max.) and Life (Min.) of master jaw of power chuck for steel (MANTEN) material under different load conditions was determined. The Auto-Grip machinery Co. Ltd Company had designed the power chuck 3H-06 model using three-dimensional drawing software (SolidWorks) to design the power chuck model. In order to evaluate the rigid body analysis and fatigue analysis, RecurDyn V9R2 software was used. In order to determine the flexible body analysis, ANSYS Mechanical APDL 19.1 and RecurDyn V9R2 were used. The simulated data allow to investigate the clamping force, contact force, Max.Stress/Max.Deformation and durability of power chuck system.
