虛擬裝配環(huán)境中的人手抓取行為與操作研究
[Abstract]:With the popularization of VR technology, virtual assembly is gradually applied to discover unknown errors in the process of product assembly, which is completed by the interaction between human hands, virtual hands and virtual assembly components. Whether the virtual grasping is realized or not will directly affect whether the virtual hand can accurately complete the assembly goal in the virtual environment. Because of the high complexity of manpower, many factors need to be considered in how to better restore the realistic assembly behavior of hand in virtual environment. This paper mainly focuses on the grasp and operation behavior of human beings in virtual assembly environment. First of all, according to the analysis of manpower structure, the manual model is constructed, which obtains the structure size through theoretical data and practical observation, which accords with the shape characteristics of human hand, and can realize the motion performance of human hand. Through SOLIDWORKS modeling and assembly of knuckles, joints and palms, the main actions of human hands are simulated. Secondly, the motion characteristics of fingers under different grasping gestures are analyzed, the fingertip motion trajectory is established, and its correctness is verified by forward and inverse kinematic analysis. The grasping rules based on grasping gestures are put forward to improve the grasping efficiency while ensuring stable grasping. Finally, the influencing factors of the two hands are analyzed, and the movement state of the left and right hands is classified according to the motion state of the left and right hands, and the interaction between the left hand, the right hand, the parts and the assembly is analyzed. Finally, the effectiveness of the trajectory of the target object is verified in MATLAB environment, and the grasping behavior of the single hand trajectory is simulated by SOLIDWORKS, and the single hand grasping is realized. An example is established to realize the assembly process of two hands under different modes. The results show that the method of establishing motion trajectory in this paper is effective, the analysis of two hands mode is feasible, and the assembly goal can be completed.
