The three undulator lines of the SHINE are referred to as the FEL-I, FEL-II, and FEL-III. Shanghai Synchrotron Radiation Facility(SSRF) will manufacture a total of 42 undulators (U26) with a period length of 26mm for FEL-I and 22 undulators (U55) with a period length of 55mm for FEL-II. Both the U26 and U55 are 4m long and use a common mechanical system. By using the specially designed double lever compensation springs can eliminate different magnetic force on the drive units. A U26 prototype has been developed and tested at SSRF. This paper describes the mechanical system design¿simulation and testing results of the U26 prototype, as well as its compatibility with U55.
