摘要
建立了复印纸张定影过程的瞬态非线性温度场数值模型 ,运用有限元 -有限差分法对普通复印纸张通过定影辊轮时的温度场的变化规律进行了仿真计算 .通过对纸张温度场的变化及力学特性的综合研究表明 ,纸张前端在通过定影辊轮 0 6s后 ,纸张温度、干燥收缩对其向上形变的影响可以忽略 ,因此分离爪应设置在距定影上辊接触点弧长为 6 0mm的最佳位置 .研究结果为复印机结构的计算机辅助工程 (CAE)的优化设计提供了理论依据 ,根据该理论依据改进后的复印机 ,大大降低了卡纸的故障 .
The transient nonlinear temperature field model of copier paper was established. The temperature field of ordinary copier paper is simulated by the finite element method and the finite difference method during passing through the fusing rollers. The analysis of the varying characters of temperature field and mechanical characters of copier paper shows that when the paper passed the rollers 0.6 s, the temperature, dryness and shrinkage of paper only slightly influence its upward deformation. Consequently, the separating claw should be mounted at the optimum position - radian length of 60 mm away from the upper roller contacting point. The conclusions provide a theoretical foundation for the CAE copier design.
