Carbon steel has high and low temperature strength is very tough and has excellent fatigue strength.
The factor of life scatter is used for depicting the dispersibility of fatigue strength in low cycle fatigue, but in high cycle fatigue is the fatigue strength reduction factor.
Based on fatigue tests, this paper studies the flexural fatigue strength of layer steel fiber reinforced concrete, and gives the flexural fatigue equation.
Some characteristics of the rolls, such as strength vs. Thermal shock, tensile strength and contact fatigue strength, influence spalling. Thus, strength was investigated as a hardness parameter.
By analyzing the force applied on the tubing, the tensile strength and anti-fatigue strength of the tubing are calibrated.
The rotating bending fatigue strength is the criterion of resistance to propagation of hot cracks.
Designs o? The closed soft surface gear transmissions are generally restricted by the contact fatigue strength.
Design method to enhance fatigue strength of a dome is given without increase of total cylinder mass.
Basing on the experiments and analyses, it puts forward a simple and feasible method of checking the fatigue strength of revolving axle in a stable state.
Depending on the reliable design theroy of fatigue strength, the paper deals with the analysis method between drum and grinding head of a ball mill.
The test results show that, the flexural fatigue strength of polyacrylonitrile fiber reinforced concrete beams with bottom layer steel fiber is larger than the plain concrete 15.7% ;
Also it is possible that the fatigue strength is greater than that of conventional cover plates perhaps because of the thinness of the slider plate.
Also, the calculation formula of the contact stress, the fatigue strength and the static strength for the small thrust bearing which are attached at the end face of roller are derived.
The thesis researched the wheelset and axle-box fatigue strength of CRH_2 trailer and expected that the results could be valuable for establishing the standards of high-speed EMU.
It has been proved by researches that the effect of the sliding friction between on the bending fatigue strength of the tooth root of the idler should not be...
