The influence of selected factors, such as wood Two-Piece sets species, veneer combinations, and loading cycles, on the bending strength and modulus of elasticity of glued laminated wood was investigated after cyclic loading of 0, 1000, 3000, and 7000 cycles with European beech (Fagus sylvatica (L.)) and Eurasian aspen (Populus tremula (L.)) The la

The problem of randomness and fuzziness of mechanical design could effectively dealed with through the fuzzy reliability optimization design which established by the combination of fuzzy mathematics method and mechanical optimization technique.Taking the multi-stage planetary gear train as research object,the optimization and allocation of transmis
