The statistical background of wave-induced bending moment, i. e. spectral density, transfer function, correlation function, distribution function, and their applications has been reviewed. The shortterm distribution of stress amplitudes-Rayleigh function, the long-term distribution of stress amplitudeslog-normal function, and the probability distribution of impact-induced bending moment-normal function have been introduced respectively. Several methods for determination of design standard of bending moment are presented, such as the design standard of bending moment may be determined by the probability of joint distribution of wave-height and wave-length at severe sea state, or by using' the rule of "3σ"or "4σ" (σ-standard deviation) adopted from statistics. After consideration of problems existing in statistical analysis of wave-induced bending moment of ships, the following conclusions are made: (1) The investigation of design standard of wave-induced bending moment is based upon the strength of an actual ship. (2) Full-scale ship trials of short-term and long-term must be carried out. (3) The actual distribution of extreme value of high stress, and the analysis of spectrum of wave-induced bending moment have to be studied.

In this paper reasons of premature failure of gear teeth of coal mining machinery are analyzed. The author points out that premature fracture of gear teeth may be caused by high-frequency cyclic loading, as well as low-frequency cyclic loading, when high stress concentration occurs. Gear teeth fracture may also occur in case of overloading. In addition to the conventional calculation on bending strength for gear teeth, it is suggested that the calculation of impact fracture and the calculation based on fracture...

In this paper reasons of premature failure of gear teeth of coal mining machinery are analyzed. The author points out that premature fracture of gear teeth may be caused by high-frequency cyclic loading, as well as low-frequency cyclic loading, when high stress concentration occurs. Gear teeth fracture may also occur in case of overloading. In addition to the conventional calculation on bending strength for gear teeth, it is suggested that the calculation of impact fracture and the calculation based on fracture mechanics must be made for gear teeth in order to provide a basis for selecting the optimum materials and heat treatment technology. Residual life for fractured gear teeth can be evaluated according to the fracture mechanics. Finally some suggestions have been made to improve the gear strength for domestic coal mining machinery.

In this paper, stress analysis has been made on a barge-carrier by the finite element method, For this new ship design, two plans of structural arrangement have been proved. The stress analysis of these structures are made in two different ways, For one of these designs, the stress of the whole ship structure is cal -culated by the finite element method, Due to the symmetry of the ship and its loading about the longitudinal axis, only one half of the whole structure should be considered. In this analysis, the domain analysed has been divided into about 1000 elements. For the other design, the stress analysis is first made by considering the whole ship structure as a simple beam to find the points of maximal stress and maximal.deflection. In general,they arelocated near the mid-section. Then a certain part of subdivision around the mid-section is re-analysed by the finite element method.The domain analysed is also divided into about 1000 elements, The meshes around the maximal stress and maximal deflection points are made denser in order to improve the accuracy of ther calculation.
