| dc.description.abstract | 本研究以華擎開發的車用發電機組（增程發電系統）為研究對象，利用模組化的包覆性結構將增程發電系統放置於結構內，此結構內部含有引擎支撐架及引擎腳作為增程發電系統與結構間的隔振，隔音擋板進行降噪，藉此達到較佳的NVH效果。其中隔音擋板使噪音降低的同時，伴隨著問題是散熱的效果下降導致內部流場溫度升高，使得各元件無法作在適當的操作溫度下運作，造成元件效率下降甚至損毀。為了解決彼此參數互相衝突的情況，本論文與降噪之論文一併進行全面性參數探討影響彼此程度的關係，並利用影響散熱程度較大的參數進行散熱流場的優化設計。本論文研究的工具以商用軟體Fluent進行散熱流場的分析，利用田口式直交表找出針對擋板的安排方式及外殼結構形狀對散熱流場影響較大的參數因子，進而利用此參數因子提出一組最佳的設計，最後加入影響降噪的參數因子如擋板的安排來探討彼此的消長關係，提出一版兼具散熱及降噪效果的包覆性結構。 | zh_TW |
| dc.description.abstract | In this study, a vehicle manufacturer’s Genset is used as our object. Using a modular package that covering the Genset , and the modular will has benefit with good performance of vibration isolation by the mounting systems and low nosing by the baffle , in order to get high NVH performance , on the other hand the baffle will let the cooling performance getting lower , led to the objects are working in the high temperature environment , and the objects will getting lower efficiency or even destroying . In order to solve the conflicting relationship with each other , this study in conjunction with the noise of the paper conducted a comprehensive parameter exploring the impaction of the extent of their relationship , and then use the large extent parameters to optimizing the thermal flow design . In this study the commercial software Fluent is the tool for thermal analyzing , which analyzing the influence of the flow field with the arrangement of baffle and the shape of package , the optimum solution will be found out in the section. Arrangements will be concerned both with the acoustic impact factor and thermal management , the acoustic and cooling performances of the developed low noise engine generator set will be found out in the end. | en |
