摘要
为了测试单体六极线圈经过绕制、热处理、环氧浸渍等一系列工艺过程后,电磁性能是否达到设计指标,设计了能够一定程度上模拟六极磁场及其应力分布的Mirror测试结构。由于Mirror结构在室温装配过程中采用Bladder-Key技术对六极线圈施加预应力,为了能够模拟从室温装配到冷却降温的操作流程、验证ANSYS有限元仿真方法与实验结果的一致性,依据六极线圈外形尺寸加工了一个模拟线圈。实验结果表明,铝壳和模拟线圈中心处的应变与ANSYS仿真计算结果基本一致,最大误差均在10%以内,验证了结构设计的合理性和仿真结果的可信性。
To test the performance of the individual sextupole coil after the process of winding, heat treatment and vacuum-impregnation, a Mirror structure based on a Bladder and Key technology during the magnet assembly was devised. In order to simulate the assembly procedure from bladder and key pre-stress at room temperature through cool-down and verity the proposed method with ANSYS, a dummy coil according to the size of the sextupole Nb3Sn coil was got. Test results of the strain in the middle of shell and dummy coil exhibit a very good agreement with expected results calculated with the structural analysis program ANSYS, and the maximum error is less than 10%. The result verifies the rationality of the Mirror structure design and the credibility of simulation results.
