摘　　要：In the SSRF Phase-II beamline project, a superconducting wiggler（SW） will be installed in the electron storage ring. It may greatly impact on the beam dynamics due to the very high magnetic field. The emittance growth becomes a major problem, even after correction of the beam optics. A local achromatic lattice is studied, in order to combat the emittance growth and keep the performance of the SSRF storage ring as high as possible. Other effects of the SW are also simulated and optimized, including the beta beating, the tune shift, the dynamic aperture, and the field error effects.In the SSRF Phase-II beamline project, a superconducting wiggler（SW） will be installed in the electron storage ring.
