摘　　要：该文结合碟式太阳能聚光器实际受风载荷的状况,运用ANSYS模拟受八级自然风时碟式太阳能聚光器的瞬态动力学特性。研究发现,工作角在0°~15°时,碟式太阳能聚光器最大位移位置在聚光镜上边缘处,工作角在30°~90°时,最大位移位置在接收器支撑板处,最大应力位置始终为骨架与跟踪系统连接板处。并以0°工作角为例具体分析了其瞬态动力学响应。In this paper,the transient kinematic of a dish solar condenser subjected to eight wind loads is simulated by ANSYS in combination with the actual wind load condition of the it. It is found that when the working angle is at 0 degree to 15 degree,the maximum displacement of the dish solar condenser is at the upper edge of the condenser. When the working angle is at 30 degree to 90 degree,the maximum displacement is at the support plate of the receiver. The maximum stress position is always at the connection point between the skeleton and tracking system. The transient dynamic response of the 0 degree angle is analyzed in detail.
