Abstract
Blade mould is the key equipment in the manufacture of wind turbine blades.Now,the opening and closing of wind turbine blade mould mainly depends on mechanical crane lifting and full-automatic hydraulic overturning.The mechanical crane lifting is discontinuous and has poor accuracy.However,the most existing automatic mould clamping devices are provided two symmetrically arranged hydraulic cylinders,the dead point may be hit and cause great damage to the hydraulic cylinders during overturning.In order to solve the above problems,in this paper,a new type of automatic clamping device for wind blades with double hydraulic cylinders is introduced,and its structure and working principle are described.The author established the geometric model of the device,deduced the mathematical model for calculating the torque of the main and auxiliary hydraulic cylinders of the hydraulic system during the overturning process,and optimized the hinge point position of the double hydraulic cylinders of the automatic clamping device through the Matlab genetic algorithm toolbox,so that the dynamic torque change of the hydraulic cylinders during the overturning process can fit the resistance torque of the load as much as possible.The optimization design results show that the size of the device can be further optimized by this method,and the efficiency and accuracy of blade clamping can be improved.关键词
