Optimal design with three variables is then done to the elbow - bar mechanism of the mp1040b moulding machine by utilizing the method of punishing function for constraint problems and variational scale for unconstraint problems. the optimal target function is the maxium of gradient in one work travel for the moulding plank of the elbow - bar mechanism. the result shows that the maximal gradient of moulding plank in one motion period declines by 25. 7 after optimization, and the angular acceleration of the bottom moulding plank decreases greatly
動力學分析中，各構件的質量和轉動慣量是通過pro / engineer軟體，先建立各個構件幾何模型而求得；然後，利用解決約束問題的罰函數法和處理無約束問題的變尺度法對mp1040b型模切機肘桿機構進行三個設計變量的優化設計，優化目標函數為肘桿機構的下模切板在一個工作行程中達到的最大傾斜程度；通過優化設計，模切機肘桿機構的下模切板在一個工作行程中的最大傾斜程度降低了25 . 7 ，其角加速度明顯減小，提高了模切機動力學性能。 -

The experiment results indicate that 90 % pressure drop is attributed to minor pressure drop in heat sink and these results are higher than the theoretical value. the thermal resistance will drop with the increasing of pumping work and the extent of the drop will decrease when the pumping work reach some value. the maximal temperature difference between the heat - sink surface and the coolant will increase with the increasing of heat fluxes, as is same to the maximal temperature difference on the heat - sink surface
研究表明，在微射流熱沉中，熱沉總阻力主要是由局部阻力引起的，佔到熱沉總阻力的90 % ;微射流陣列冷卻熱沉熱阻隨泵功的增加而減小，但是當泵功增加到一定程度時，熱阻變化趨于平緩;熱沉散熱片底面溫度和溫差隨熱流密度增加而升高，但是溫差保持在一定范圍之內。
