摘要

基于随机抽样理论

建立光线追踪风致振动镜面聚光分布预测模型

采用流场-结构-光学多物理场瞬态计算方法

以太阳位置、定日镜仰角及方位角为变量

获得脉动风荷载作用下反射镜面聚光分布变化规律

对聚光效率、净风荷载及镜面位移等关键物理量进行脉动、时程及高斯特性分析。研究结果表明：风致振动导致定日镜聚光效率下降8.26%~19.48%

正午时刻镜面聚光效率损失达到最大

镜面变形每增加1 mm

聚光效率损失增加约2.87%;随着风速增加

镜面净风压和平均位移呈正相关增长趋势

聚光效率表现为负相关变化规律;镜面净风压、平均位移及平均聚光效率的波动特征表现出瞬时同步性。

Abstract

Based on the theory of random sampling

a ray-tracing model for predicting the wind-induced vibration of the mirror surface and its concentrating distribution is developed. A transient multi-physics approach is employed

integrating the flow field

structure

and optics. The model takes the solar position

heliostat elevation angle

and azimuth angle as variables

and analyzes the variation in the concentrating distribution of the mirror surface under pulsating wind loads. Pulsation

time-history

and Gaussian characteristics of key physical quantities such as concentrating efficiency

net wind load

and mirror displacement are also examined. The results show that wind-induced vibrations cause the heliostat’s concentrating efficiency to decrease by 8.26% to 19.48%

with the maximum efficiency loss occurring at noon. For every 1 mm increase in mirror displacement

the concentrating efficiency loss increases by about 2.87%. As wind speed increases

the net wind pressure and mean displacement exhibit a positive correlation

while concentrating efficiency follows a negative correlation. The fluctuation patterns of net wind pressure

mean displacement

and mean concentrating efficiency display instantaneous synchronization.
