查询词典 arbitrary constant

The first process is to optimize the geometric parameters of the press, on the assumption that the servomotor rotates at a constant angular velocity equal to that of the constant velocity motor. The second process is to optimize the displacement trajectory of the servomotor based on the results of the first process while keeping the geometric parameter unchangeable.

然后，建立了混合驱动压力机的优化设计模型，并将优化分为两步：第一步，假定伺服电机角速度与常规电机相同的条件下，优化设计出压力机的尺寸参数；第二步，在第一步优化结果的基础上，使机构的尺寸参数不变，优化设计伺服输入运动规律。
