【Abstract】 Based on the actual operations of concrete-pump vehicles,the calculation method for theoretical loading values is proposed under the most dangerous working conditions on diverse booms.Then,the layout optimization on the cylinder-rod mechanism of boom system is developed using the improved genetic algorithm,viz.,encoded by floating point number.Through simulation model validation,the optimized layout options are obtained with operational property satisfaction and significant reduction of various cylinder lengths and pressures.Finally,this approach paves a venue for intelligent design on boom systems of concrete-pump vehicles.更多还原
