求翻译：轴承分析是一个接触分析问题。滚动体在载荷为零的情况下与圈体接触为一点。随着载荷的增加，点接触变成面接触。接触区域的大小、位置、形状、接触面压力及摩擦力分布等接触参数在分析前都是未知的，它们随着载荷的变化而不断变化，是工程应用中的一个难点问题。是什么意思？

Bearing analysis is a contact analysis. Rolling element in contact with the ring body load zero point. With the increase of the load, the point contact into surface contact. Contact area size, location, shape, the contact surface pressure and friction distribution of contact parameters are unknown p

Bearing analysis is a contact problem analysis. Scroll down to zero load in the body and turns to a contact point. As loads increase, Point of Contact into a face. Contact area of the size, position, shape, surface pressure and friction parameters, such as distribution in the analysis of the former

The bearing analysis is a contact analysis question.The rolling body in the load is in the zero situation and the circle stereoscopic contact is.Along with the load increase, selects the contact to turn the surface contact.Contacts contact parameters and so on the region size, position, shape, conta

Bearing analysis is an analysis of contact problem. Rolling load cases and contact with zero points. As the load increases, contact into contact. Contact area size, position, shape, distribution of contact pressure and friction contact parameters before the analysis is unknown, they are changing as
