摘　　要：针对剪叉式液压升降台在工作过程中存在活塞最大推力偏大、液压系统工作压力偏高的问题,建立剪叉起升机构力学模型,以活塞最大推力为优化目标,对影响起升液压缸最大推力的位置参数进行优化。优化后活塞推力减小37%,验证优化的有效性,为剪叉式起升机构的设计计算提供理论依据。In the working process of scissors elevating platform,the biggest thrust of the piston is too large and the pressure of hydraulic system is too high.To overcome these shortcomings,based on establishing hydraulic scissors elevating platform mechanical model,the parameters affecting the biggest thrust of the lift cylinder were optimized taking the biggest thrust of the piston as object.The optimization results show that the biggest thrust of the piston decreases 37%.It verifies the validity of the optimization and pro-vides reference for the design of the scissors elevating mechanism.
