| 中文摘要: |
| 在进行离心试验前，需要对离心机吊篮进行配平。对于大质量试验件，经常由于其质心位置尺寸不够准确，难以进行精确配平，当加速度载荷很大时，离心机吊篮耳轴会承受很大的不平衡扭矩。针对离心机吊篮转轴结构的特殊性，提出采用粘贴应变片、根据测点应变计算扭矩的测量方案，并进行了测量原理分析和试验验证。 |
| 英文摘要: |
| It’s necessary to equipoise the suspended basket of centrifuge before centrifugal test. But the accuracy is not always compatible with uncertain center-of-gravity station of massive sample. There will be unbalanced moment acting on the trunnion, with high centripetal acceleration. In allusion to the especial structure, the method of using strain gauge to measure the trunnion torque of centrifuge suspended basket was proposed. Accordingly, the principle was enunciated, and the experiment was described to show that the theory and method is correct and feasible. |
