摘要:
为设计新型并联式液压压力机,使其获得良好的运动学和静力学性能,提出用杆件无量纲参数建立其尺寸模型,该模型在有限区间内描述了并联式液压压力机所有可能的尺寸组合,模型空间中的任意一点代表具有相同或相似性能的同一族压力机结构。基于机构学理论建立了并联式液压压力机输入和输出间的运动学和静力学关系,提出以有效行程和平均输出力作为描述运动学和静力学性能的评价指标,并根据尺寸模型及定义的性能指标绘制了反映其机械性能与尺寸参数组合关系的性能图谱。基于性能图谱,可以对并联式液压压力机进行优化设计。
Abstract:
To design a novel parallel hydraulic press with prominent kinematics and statics performances,the dimensional model of the parallel hydraulic press is established by member dimensionless parameters.All the possible dimensional parameter combinations of the parallel hydraulic press are expressed in a finite region and each point in the region corresponds to a group of mechanisms having the same or similar performance.Based on the mechanism theory,the relationships of kinematics and statics between the input and output for the parallel hydraulic press are established.Two performance evaluation indexes of kinematics and statics performances,namely effective stroke and average output force,are presented.The performance atlases describing the relationships between the dimensional parameter combinations and mechanism performances is obtained based on the proposed dimensional model and evaluation indexes designed.Based on the performance atlas,the design of parallel hydraulic press can be optimized.
