This study checks and analyses the design of a disk braking caliper bench testing machine, to testify its moving characteristics. The analysed objects include rotating axes and four weighting disks. The first procedure is to use the design software SolidWorks to build axis and weighting disks models. Next, the models are transferred to the finite element analysis software ANSYS to add boundary conditions and to conduct mode analysis. The ANSYS simulates axis and four weighting disks rotating stress analysis under 2000 RPM condition. The results show axis full-loaded rotating natural frequency is 74 Hz (4,440 RPM), the frequency is far away from working speed 2,000 RPM. The maximum stress is 67.9 MPa; when the stress is compared with material's ultimate stress is more than 10 times. The maximum displacement at disk is 0.056 mm. The design should carefully check the tolerance between disk and machine cover. So the result of this design is safe. These design parameters can use for design check and machine manufacturing.
