摘要
Counter-balance boom of tower crane with upper part rotating is studied.The writers use the grid optimum method with continuous and dispersed mixing variable.Design variable is section steel number.Several parameters and members of counter-balance boom are optimized.Its optimum length and mass are obtained.Calculation result shows that the optimum method is simple and practical.The calculation and program show that the calculating speed is fast and it can commonly be used.
