The basic performance and designing principle of a kind of elastic layer material, which were applied in the Roller Mill to reduce the machine noise, were introduced.

The impact frequency caused by steel balls in 350/700 Roller Mills on the lining plates and the innate frequency of the system consisting of “lining plate elastic layer cylinder” are calculated.

Design and practice of elastic cushion layout of the power penstock in Manwan Hydropower Station;

Emphasis is laid on the application of elastic levels of isolation and floating slab track.

Numerical analysis of the deformation of elastic cushion and its effect on the forming results in MPF of sheet metal;

To obtain the exact object shape, the forming surface of MPF must be corrected based on the deformation of elastic cushion.

The dimples can be suppressed effectively by application of the elastic cushion and the thicker the elastic cushion the better its dimple suppression effect,but thick cushion leads to large error between the shape of the obtained part and its target shape.
