注意：
1、六连杆运动屏显程序、六连杆受力屏显程序、凸轮数据屏显程序没有打印出来。
2、由于各文本输出程序分析结果数据量过大，程序中使用5度为分度，打印时用了15度。
题目：
如图所示的六连杆机构中，已知l1=0.12m,l3=l4=0.6m,l6=0.38m;
曲柄1逆时针方向等速转动，转速n1=172r/min;
构件质量m3=20kg,m4=15kg,m5=62kg,构件1、2的质量忽略不计；
质心位置lCS3=0.3m,lDS4=0.3m,质心S5在点E；
构件3、4绕质心的转动惯量JS3=0.11kg·
m2；
该构件在工作行程时滑块5受生产阻力Fx=110N。
求：
1）曲柄回转一周过程中，滑块5的位移SE、速度υE、加速度aE及构件3、4的角速度ω3、ω4，角加速度α3、α4；
2）各运动副中的反力及应加在原动件AB上的平衡力矩Mb。
