RESEARCH ON THE FATIGUE LIFE CALCULATION METHOD OF HYDRO-TURBINE HEAD COVER CONNECTING BOLTS BASED ON PD-STFA by LIU Yu, JIN Jian, WANG YongFei, ZHAO JunJie, YU Bo

“…Long-term alternating loads on the connecting bolts of hydro-turbine head cover,which results in fatigue damage causing many serious accidents.Therefore,it is necessary to carry out in-depth study on the calculation method of fatigue life of head cover bolts in order to improve the accuracy of fatigue life calculation.In order to solve the above problems,a method for calculating the fatigue life of Turbine head cover bolts based on combination of power density and short-time Fourier analysis（PD-STFA） is put forward,with emphasis on the influence of coupling action of loading frequency and amplitude load on the fatigue life of head cover bolts.Firstly,the position and stress of dangerous section of connecting bolt are calculated by finite element method;secondly,the average stress of contact surface of bolt head is measured by strain-based hollow pressure sensor,and then the measured average stress of contact surface of bolt head is transformed into the stress of dangerous section according to generalized Hooke’s law;finally,based on linear damage accumulation theory,the fatigue life of the head cover bolts is calculated by PD-STFA method and the traditional rain flow counting method.The calculation results show that the fatigue life of the head cover bolts is 1.966× 10~5 h based on PD-STFA method and 4.113 ×10~5 h based on traditional rain flow counting method.According to the investigation of power plant users,the calculation results based on PD-STFA method are closer to the actual service life of bolts for about 30 years,and can predict the fatigue life of the turbine head cover connecting bolts more accurately,thus providing theoretical guarantee for the safe and stable operation of the hydro-turbine.…”

Calculation of Involved and Noninvolved Organs Doses in Carbon Therapy of Brain Tumor Using GEANT4 Simulation Toolkit by Maria Ahmadi, Seyed Mohammad Motevalli, Payvand Taherparvar, Vahid zanganeh

“…Beam parameters were also evaluated per ICRU guidelines.Results: This study estimated the flux and dose distributions of secondary particles—protons, electrons, neutrons, alpha particles, and photons—in the brain tumor and surrounding tissues. We calculated the cumulative dose from both carbon ions and secondary particles, finding an absorbed dose ratio of 0.003 in healthy brain tissue compared to the tumor, with values of 4.8 × 10-4 for the skull and 2.6 × 10-5 for the thyroid. …”

Study on the Calculation Method of the Diffusion Range of Grouting Slurry for a High-speed Railway Ballastless Track Subgrade by Changwei Yang, Jinhao Guo, Shaowei Wei, Liang Zhang, Sifeng Li, Yang Liu

“…The numerical simulation results show that, in the grouting process, the greater the grouting pressure, the wider the diffusion range of the slurry and the greater the damage to the microscopic contact force of the slurry to the soil; in addition, when the grouting pressure is below 0.15 MPa, the diffusion form of the slurry in the soil is osmotic grouting; when the pressure is about 0.3 MPa, the diffusion form of the slurry in the soil is compacted grouting; on the basis of the simulation results, a deeper research is carried out, and the calculation formula of the slurry diffusion curve is obtained. …”
