Considering the processing method of roller and mold, the surface roughness Ra is in the range of 1.6-25 μ m.

It is assumed that the geometric errors of the left roller, the right roller and the outer circle of the

If the mold has eccentric mass at the roller support, the eccentricity is e = 0.03mm, and the phase angle

The transfer matrix method is also used to calculate the dynamic performance of the cast rotor. Firstly, the rotor is

At any time t, the lower part of the mold contour always contacts with a point of the upper part

The microscopic shape of an object’s surface is called surface topography. No matter what method is used to process the

In fact, due to the influence of processing accuracy and other factors, the profile of roller and mold will produce

Establish the coordinate system origin 0 as shown in Fig. 1, which coincides with the center of the left roller,

There are two types of excitation on the rotor of rotating machinery, one is the excitation force acting on the

In the theoretical calculation, the theoretical model is still consistent with the model described, but in the programming calculation, some

In order to verify the correctness of the theoretical model in this chapter, an experimental device for vibration measurement of

There is an eccentric mass on each section along the axis of the mold. The eccentric mass on the i-th

Through programming calculation, the first four critical speeds of centrifugal casting machine can be obtained. It can be seen that

Taking the horizontal roller supported centrifugal casting machine of an equipment manufacturing Co., Ltd. as an example, the vibration performance
