一种碟式聚光器反射表面的抗冲击特性仿真模拟

Impact Resistance Simulation of Reflective Surface on a Kind of Dish Solar Concentrator

由于太阳能聚光碟片结构相对复杂，试验成本相对过高，冲击过程中所受到的应力大小和变形量均不便从试验中直接得出。为研究一新型结构的太阳能聚光碟片的抗冲击特性，本文采用ANSYS／LS—DYNA软件建立了该种聚光碟片有限元模型，并对不同厚度的反射玻璃的抗冲击特性进行模拟仿真分析。

Since the structure of dish solar concentrator is relatively complex, test costs are relatively high, The stress and deformation value suffered during the impact are inconvenient obtained directly from the test.In order to study＇ impact properties of a new structure dish solar concentrator, In this paper, we build finite element model of this kind of dish solar concentrator by ANSYS / LS-DYNA software, and simulate impact properties of reflecting glass of different thickness.
