问答题：
1．机构具有确定运动的条件是什么?
答：机构自由度大于等于1，当机构的原动件数等于自由度数时，机构具有确定的运动。

2．什么是运动副？什么是高副？什么是低副？
答：使两个构件直接接触并产生一定相对运动的联接，称为运动副。

以点接触或线接触的运动副称为高副，以面接触的运动副称为低副。

3．螺纹的导程S与线数n及螺距P之间的关系是什么？
答：导程S：在同一螺纹线上相邻两螺纹牙之间距离。

线数n：在同一圆柱面上制造螺纹线的数目。

螺距p：相邻两螺纹牙平行侧面间的轴向距离。

因此
np S
1、联轴器与离合器的主要功用和区别是什么?
答：联轴器和离合器主要都是用来联接两轴并传递扭矩，用联轴器联接的两根轴，只有机器停止运转后，经过拆
卸才能分离，而用离合器联接的两根轴在运转过程中能随时根据需要结合或分离。

1．什么是构件的强度？什么是构件的刚度？
答：强度是构件抵抗破坏的能力，满足强度要求是指在外力作用下构件不发生破坏。

（讲评：注意定义）刚度是构件抵抗变形的能力，满足刚度要求是指在外力作用下构件的弹性变形量不超过允许的限度。

1．为什么将蜗杆分度圆直径dl规定为蜗杆传动中的标准参数？
答：为便于加工蜗轮刀具的标准化，一般将蜗杆的分度圆直径规定为标准值。

2．为什么蜗杆的传动比i只能表达为i＝z2/z1，却不能以i＝d2/d1来表示？
答：因为蜗轮蜗杆传动的传动比与蜗杆的直径无关。

1．带传动产生弹性滑动和打滑的原因是什么?对传动各有什么影响?
答：由于带是弹性体，带紧边与松边拉力不同，由于带的弹性变形量的变化而引起的带与带轮间的相对滑动。

打滑是带传递的圆周力大于带能传递的最大有效圆周力，引起的带在带轮上全面滑动的。

弹性滑动将引起：
（1）降低传动效率；
（2）从动轮的圆周速度低于主动轮，造成传动比误差；
（3）带的磨损；
（4）发热使带温度升高。

打滑造成带的磨损加剧，无法传递动力，致使传动失效。

3．为什么多数螺纹联接工作前均要预紧？如何控制预紧力？螺纹联接的主要防松方法有哪些？
答：预紧的目的是为了增加联接的刚性、紧密性和防松能力。

用测力矩扳手和定力矩扳手
机械防松摩擦防松其他防松
2．试分析增速带传动工作时，其最大应力在哪里?
答：带紧边刚绕出小带轮处

2．根据尺寸和机架判断铰链四杆机构的类型。

答：a ）双曲柄机构 b ）曲柄摇杆机构 c ）双摇杆机构 d ）双摇杆机构
3．在图示铰链四杆机构中，已知，lBC=150mm ，lCD=120mm ，lAD=100mm ，AD 为机架；若想得到双曲柄机构，求lAB 的最小值。

解：要得到双曲柄机构，因此AD 杆必须为最短杆； 若AB 为最长杆，则AB ≥BC ＝150mm 若BC 为最长杆，由杆长条件得： CD

4．画出图示各梁的剪力图和弯矩图，并计算最大max Q 和max M 。

0=∑B M 024=++-F M R A 25.6=A R kN 75.3=B R kN
由 0=∑Y 得知 支反力计算无误。

由几何关系我们得知求出几个重要点的剪力和弯矩值我们就可以画处图像。

下面我们开始求在下列几处的剪力值： 在A 点左截面，0=Q
在A 点右截面，25.6==A R Q kN 在C 点左截面，25.6==A R Q kN 在C 点右截面，75.3-==B R Q kN 在B 点左截面，75.3-==B R Q kN
在B 点右截面，0=Q 画出剪力图，如下图： 同理我们根据几何关系求处几处弯矩值：
在A 点，0=M
KN R M A C 5.122=⨯=左 KN M R M A C 5.72=-⨯=右 在D 点，0=M 画出弯矩图，如下图：

（2）解：此题解法和上个题步骤基本相同，我们也可以用另外一种方法解题，下面我们用另外一种解法进行求解：

根据几何关系，AC 段没有载荷作用，弯矩图为一条斜直线；在C 点有集中力偶，弯矩图有突变， CB 段有均布载荷作用，弯矩图是一条抛物线。

为了做弯矩图，只需求出梁在下面各截面处的弯矩值：
在点A ， 0=M

在C 点右截面 2

在点B, 0=M
此外由剪力图知道，在CB 段内有一截面的剪力为零，这个截面的弯矩是梁CB 段内弯矩的极值。

即该点的
