Basic Loop

This paper proposes a simulation method suitable for weft-knitted seamless kneepads. The purpose of this study is to realize the simulation of complete weft-knitted products, and it has the advantage of speed to display the simulation results online in real-time. The loop of the basic loop model is controlled by up to eight characteristic points and the yarn path is fitted by a three-dimensional spline curve. To string the loop model into the fabric, the coordinate of the characteristic point of the loop at other positions is obtained based on the loop model at the origin by using the translation matrix and the rotation matrix. The simulation of the weft-knitted kneepad is realized by the joint programming of Visual Studio and WebGL. The results show that the structure model can achieve the simulation of the kneepad with high efficiency. This method has strong real-time performance and practicability.

Computed Torque

A method of force allocation by optimizing the friction angles at finger contacts was combined with the computed torque method to find the torques to be commanded at finger joints for multifingered systems. In this way, slip can be avoided when the object is grasped or manipulated. The proposed method can be used to efficiently find the input torques, and is applicable for real-time computation. A history-based method is also proposed to improve the smoothness of the input torque commands. Three-dimensional simulation results are given.

This paper introduces the modular structure of NC turning simulation system and the characters of OpenGL. OpenGL is the standard interface of three-dimensional graphic software, and its main functions include modeling, transformation, mode setting of color, light and material setting, texture mapping, double buffer animation, etc. The application of OpenGL in development for NC turning simulation system is described, at the same time, its effect on three aspects of solid modeling, realistic effect and animation demonstration is specially illustrated. Simulation results prove that the NC turning simulation system based on OpenGL runs reliably, and can effectively simulate the machining process in real time.
