摘要：Under three-dimensional plane geometrical constraints ( X,Y,θ ), with two asymmetric achromatic sections, the combined three-section structural FODO-like magnet lattice design is adopted and finely optimized in the SSRF electron-beam transfer lines. The magnet lattice has high flexibility and robustness, and the Courant–Snyder parameters can be easily adjusted within a wide range to meet the requirements of transmission and injection for different operation modes of the linear accelerator, booster synchrotron, and storage ring. In this article, the main parameters of the linear optics design of the SSRF electron-beam transfer lines are described, involving the physical design criteria, the total geometrical layout, the magnet lattice, and the beam Courant–Snyder parameters matching. The studies of the variant beam dynamic simulation program calculations show that the design purpose of the efficient beam transmission and injection will be basically achieved.

摘要：采用试验和数值模拟相结合的方法,开展了爆炸箔起爆器(ExplodingFoilInitiator,EFI)在慢烤、快烤条件下的热安全性研究。设计并组建了一种适用于EFI等小型火工品的烤燃装置,开展了EFI烤燃试验;同时,利用ANSYS/FLUENT对EFI烤燃响应状况进行了数值仿真计算。试验结果显示:EFI在10K/h慢烤条件下响应时间约为25.8 h,响应温度约为555K;在快烤条件下响应时间约为135min,响应温度约为565K。在两种条件下EFI响应等级均为爆燃。将数值模拟结果与烤燃试验结果进行对比分析,数值模拟与试验响应时间相差小于10%,响应温度相差小于2%。研究表明本文设计组建的烤燃装置适用于EFI的烤燃试验,数值模拟模型较为准确。

摘要：为提高大量程六维力传感器的灵敏度,设计了一种适用于机械臂末端的应变式传感器。该传感器采用十字梁式弹性体结构,通过优化应变梁结构和合理布置应变片等方式,使传感器在大量程条件下仍具有较高的刚度和灵敏度。使用有限元法分析验证了传感器应力分布的合理性,并根据最小二乘法标定原理对传感器进行解耦标定实验,实验结果表明:传感器静态性能良好,最小灵敏度为0.375 m V/N,满足使用要求。
