Abstract:

To increase the operating range and improve the flexibility of the mechanism， a scissor aerial work platform with a rotating and telescopic power device was developed. Based on the preliminary design of the basic dimensions of the scissor aerial work platform， an analysis of the anti-overturning stability was conducted. When the operating platform was rotated to an angle of 90° with the bottom plate， the mechanical model was established to verify its load stability requirements by the stability coefficient method， and the speed and acceleration of the working platform were calculated using the cartesian coordinate method and the instantaneous velocity center method. The hydraulic cylinder thrust was obtained by the principle of virtual work， and the hinge point position of the lower hydraulic cylinder was optimized by genetic algorithm. Finally， dynamic simulation and comparative analysis were performed using ADAMS， and combined with the physical acceleration and velocity measurement results of the work platform， the correctness of the theoretical calculation and simulation results is verified.
