摘要:针对碟式太阳能发电装置俯仰传动系统实际应用中存在的问题,提出了俯仰传动系统的优化设计方案。利用Adams软件对比分析不同角度偏差作用下系统推杆的运行状况。仿真结果显示:未改进模型在一定安装偏差角作用下,推杆受到较大的侧向力作用,推杆处在危险工况。通过优化支撑组件结构,推杆所受侧向力大幅减小,最大侧向力仅为109N,与轴向力相比可忽略不
计。在实际应用中推杆运行平稳,改进效果明显。关键词:碟式太阳能装置;推杆传动;安装偏差;优化

Abstract: In view of the application problems of the pitch drive system for disc solar power generation de-vice, optimizing design scheme is proposed for the pitch drive system. Adams software was used to ana lyze the operation condition of push rod system with different installation deviation angles. The simulation resuits show that before optimization, the lateral force of the push rod was relatively large under the effect of installation deviation angle, and was working under dangerous condition. By optimizing the structure of the support assembly, the lateral force of the push rod was reduced substantially and the maximum lateral force was only 109 N, which was negligible compared with the axial force. The push rod also runs smoothly in practice, the improvement effect is obvious.

0引言
近年来碟式斯特林太阳能发电技术取得了较快的发展"]。碟式斯特林发电系统利用旋转抛物面反射镜将太阳光汇聚到置于抛物面焦点处的接收器上,接收器内工质被加热,驱动斯特林发动机工作,进行发电。该系统具有光电效率高、耗水量
小、发电方式灵活等优势[2]。碟式斯特林发电系统一般由立柱、碟板、横梁轮毂、斯特林发动机、传动系统等组成。由于碟式太阳能发电系统在工作中为保证发电效率,须实时跟踪太阳方位角,因此要求传动系统精确可靠。碟式太阳能发电装置的传动系统主要包括水平回转系统和俯仰传动系统[3]。本文利用Adams软件对推杆系统进行动力学仿真,
