【摘要】 对空间3-TPS并联机床的静平衡问题进行了理论分析及仿真优化.首先分析了机床自重产生的惯性力(力矩)对机床所造成的影响及驱动杆在整个工作空间中的输出力变化规律,然后采用液压平衡法和弹簧法平衡并联机床自重所造成的惯性力(力矩),最终大幅度降低了机床三驱动杆的输出力,实现了并联机床静平衡的目的.更多还原

【Abstract】 The static balancing of the spatial 3-TPS parallel machine tool is discussed theoretically and simulated for its optimization.Analyzes how the inertia force or the moment of inertia due to the deal weight of 3-TPS affects the machine tool and how the force output from the bar actuators changes in its whole working space.Then,the inertia force or moment of inertia due to the deal weight of the machine tool is balanced by way of hydraulic/spring balance.As a result,the force output from the three bar actuators decreased greatly to keep the machine tool in static balance.更多还原
