摘　　要：为扩大空中可操作范围,提高机构的灵活性,开发了一种带旋转伸缩动力装置的剪叉式高空作业平台。在完成基本尺寸初步设计的基础上,对作业平台抗倾覆稳定性进行了分析。当作业平台旋转至与底板夹角为90°时,通过建立力学模型,以稳定系数法验证了其载荷稳定性,以直角坐标法和瞬时速度中心法计算出作业平台速度和加速度。通过虚功原理得到液压缸推力,并采用遗传算法对下液压缸的铰点位置进行了优化。最后,采用ADAMS软件进行动力学仿真对比分析,并结合作业平台实物加速度和速度测量结果验证了理论计算和仿真结果的正确性。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.
