板簧itf文件，求大神知道！
昨天就建立了个板簧的itf文件，可是导入生成的模型时候，死活生不成。但又不知道具体哪里出错，请坛子中的大神现身指导下。还有在AXLE中设置里面有3处不懂：1、Reference Marker Height at Design load
2、Rise to Curb
3、Reference Marker to leafpack
虽然有英文帮助，可还是模糊，还请大神指导。
Itf文件如下（附件无法上传- -，不知道什么原因）：

这个如果测量弧长不应该完全等于230吧 1、Reference Marker Height at Design load
2、Rise to Curb
3、Reference Marker to leafpack
1、2、都可以理解为 车桥中心 在整车坐标系中的Z坐标，一般两者设置成一样的，主要用于生成板簧形状的设置，一般要求板簧是自由状态的，然后通过设置1、2的值，得到设计状态，就会自动有预载了，如果给的板簧是设计状态，1、2车桥中心也是设状态的值，建出来的板簧是没有预载的。
3、就是车桥中心到板簧第一片表面夹持中心点的距离。
具体错误一般都会给你提示的。 看你文件的板簧各片设置，不知道你的各片长度是测得直线长度还是弧长感觉你测的是直线长度， 正确的应该是弧线长度 77043839 发表于 2014-8-21 21:19

你好！我这提示的信息只是让你重新校对下itf文件，重试一下。没有其他信息了。你若有时间的话，能帮忙看下itf文件哪里的错误吗？不胜感激 会不会就是我说的板簧长度比如最后一片 明显是有弧度的可是你给的长度只是在X方向的长度 你先看下是不是这方面的原因如果不行我再帮你看吧 77043839 发表于 2014-8-21 21:22
看你文件的板簧各片设置，不知道你的各片长度是测得直线长度还是弧长感觉你测的是直线长度， 正确的应该 ...
板簧是1450跨距的，板簧固定支架和吊耳支架X方向是1420，吊耳长85，板簧加紧弧高125.我测得长度是弧线长度。 77043839 发表于 2014-8-21 21:38

多谢大神，问题解决了，不胜感激！以后恐怕还要多多想大神学习！望不吝赐教！ 是什么问题呢，大神当不起，互相交流吧！ 77043839 发表于 2014-8-21 23:18

你好，我把板簧和软件自带的steering_suspensiong模板装在一起，同向跳动，报错，如下：
Static equilibrium analysis has not been successful.
The maximum number of iterations 25, has been reached.
For the last attempted iteration:
The equation with the largest error was model.leaf.lfl_aft2_part_7 Comp = 6 Error = 9517751049.013542
The variable receiving the largest increment was model.leaf.lfl_leaf_2_3_joint Comp = 5 Delta = 12538841206.374254.
请问，这个是板簧模型中哪个地方出错了？ shixizixin 发表于 2014-8-23 10:22

应该是连接的问题吧，你可以测试下通讯器的连接，或者在装配体中查看约束是否正确。 shixizixin 发表于 2014-8-23 10:22

你好，我也遇到这样的问题，麻烦问一下你这个问题最后解决没，我重新检查了一下通迅器，没有问题，刚开始我查了，在板簧生成时有报错的一此信息，有两个BUSHING编号有问题，然后就是板簧右侧板簧座命名有问题，反正尝试了很多，都没有成功，想问一下你用leafspring最后做成功没有 ipqpvss 发表于 2016-7-31 17:20

会不会就是我说的板簧长度比如最后一片 明显是有弧度的可是你给的长度只是在X方向的长度 你先看下是不是这方面的原因如果不行我再帮你看吧
