Calculation of Interface Width and Contact Stress of Spinning Top Roller and Roller;

The calculation of contact stress of rock bit floating ring journal bearing under disalignment;

Numerical simulated analysis of the contact stress on the sealing rubber of the packer;

This paper focuses on the contacting stress between the plunger and the seal ring,and analyzes the effect of the seal ring structure parameters on the contacting stress.

On the basis of theoretical study on the high speed cylindrical roller bearing a finite element analysis was carried out on the common steel bearings and the ceramics bearings, and the influence of rotary speed on the contacting stress and the equivalent stress.

According to the calculation on the contacting stress and the linear speed of the gear in the hoist of the 16t-30m portal crane,the N460 heavy duty industrial gear oil was selected instead of the recommended lube oil in instruction book.

Based on large quantity of observed results,the contact pressure on soil between piles and the contact pressure on piles are assumed to distribute in a parabolic form.

Having studied present analysis method on the contact pressure of flexible bearings.

Described are the research achievements in reducing the contact stresses at the wheel-rail interface and the wheel-rail forces in North American Railroads.

During the construction process,the change of groundwater level results in the change of the water pressure under foundation,and then the change of the distribution of contact stresses.

Studies have shown:Bear the weight of increase of strength with the shaft,the shaft exposed to contact stresses increase to some extent,exposed to width increase wide too,the shearing stress function some distance most exposed to superficial depth increase, have sure influence in wearing.

Effect of mates and slide rate on wear resistance of 40Cr steel strengthened by electrical dischange was investigated under a large contacting stress.
