A refined stress-strain analysis in the load transfer zone of flat specimens of high-strength unidirectional composites in uniaxial tension 3. Effect of grip misalignment

The influence of a preliminary bending induced by misalignment of the grips of a testing machine on the stress-strain state of a flat specimen made of a high-strength unidirectional carbon fiber composite under uniaxial tension is estimated. An analysis of the analytical solution obtained is carried out, and the results of finite-element calculations and modeling experiments are presented. __________ Translated from Mekhanika Kompozitnykh Materialov, Vol. 43, No. 6, pp. 745–760, November–December, 2007.     

Productivity of tillage loosening and separating machines in an aggregate with tractors of various capacities

Currently, chemical methods of weed control are increasingly being replaced by mechanical weeding. One of the promising mechanical devices for weed control is a rotary loosening and separating stratifier. This tillage machine can provide high quality tillage to a depth of up to 18 cm. Its performance is determined by the width of the grip of the gun and the speed of movement and is limited by the traction capabilities of the tractor. Using the Goryachkin formula for the traction resistance of a tillage machine, the authors obtained the dependence of productivity on the width of the grip and the speed of movement at different depths of tillage. The obtained dependencies on the example of tractors John Deere 8330, HTZ 16131-05 and MTZ 1523.3 showed the presence of a pronounced maximum, which led to the solution of the optimization problem. The article presents a method for calculating the optimal width of the grip and the speed of movement that ensure the maximum productivity of the tillage machine, depending on the depth of processing and the specific resistance of the soil. The use of optimal parameters of the tillage machine allows you to increase its productivity by 2–3 times.     

自我感觉能力的实验性研究

研究认为自我感觉能力随负荷的减小而降低,其误差率增大,实施小负荷的动作,往往用力较大,导致耗能、动作不协调等现象。
