摘要
为了减小非同轴双输出脉冲发生机构输出角速度的脉动值,运用刚体动力学软件ADAMS进行参数化建模,并结合MATLAB进行数据分析,得到了双输出杆的速度、加速度的变化规律,以及机构平均输出角速度、脉动值及角速度突变量随曲柄长度变化的变化规律,通过实例仿真分析,验证了机构输出运动的一致性,曲柄调速的可调性;并得到了机构的脉动值随着曲柄长度增加而减小的变化规律。同时,分析了杆长OE和EF对机构双输出运动规律的影响,表明增加杆OE和EF的长度后,机构脉动值明显降低,为该脉冲发生机构的尺寸综合及优化提供了理论依据。
In order to reduce the pulsation of output angler velocity of the non-coaxial style of two-output impulse generating mechanism,by using rigid body dynamics software ADAMS for parametric modeling,and combining the MATLAB for data analysis,the variation law of the double output rod angular speed and acceleration and the institutional average,pulsation coefficient and abrupt change of angular acceleration with crank length change are obtained.Through the simulation analysis of example,the consistency of output motion and the crank speed adjustability are verified,and the variation law of the mechanism pulsation will be decrease with the increase of crank length.Finally,the impact of long-rod OE and EF change on the double output motion law of mechanism is analyzed,it is shows that,after increasing the length of the rod OE and EF,the mechanism pulsation decreased,a theoretical basis of the dimension synthesis and optimization of the impulse generating mechanism is provided.
