9807853 Shareef An SGER award supports cooperative studies between Bradley University and Caterpillar, Inc. under the GOALI program. The purpose is to develop analytical solutions for the elastohydrodynamic conditions in the cam/roller contact system, where unusual challenges exist due to high friction and contact load and significant surface roughness, and where conditions continually change during the operation cycle. The analytical work will be supplemented with post- mortem analyses of the nature of the damage to actual cams and the locus of the damage initiation, combined with simulation tests in a test rig to be constructed at Caterpillar. ***

9807853 Shareef SGER奖支持布拉德利大学和卡特彼勒公司之间的合作研究。根据GOALI计划。 其目的是为凸轮/滚子接触系统中的弹性流体动力学条件开发分析解决方案，其中由于高摩擦和接触载荷以及显著的表面粗糙度而存在不寻常的挑战，并且其中条件在操作循环期间不断变化。 分析工作将通过对实际凸轮损坏性质和损坏起始位置的事后分析，以及在拟在Caterpillar建造的试验台中进行的模拟试验来补充。 ***
