摘要
橡胶扭振减振器在中小型内燃机上应用比较普遍 ,其特性对所匹配发动机的扭振影响很大 ,目前其特性参数测试技术不能适应匹配的需求。本文介绍了一套自行研制的内燃机橡胶扭振减振器特性参数计算机自动检测分析系统 ,它基于正弦扫描法 ,实现了检测过程—数据分析—检测报告全过程的自动化。用该系统和 (B&K)测试系统对同一样件进行测试的结果表明 ,该系统能准确测定出减振器的特性参数 。
Torsional vibration dampers for crankshafts are widely used in internal combustion engines. Characteristics of the dampers affect greatly engine's performance, yet there is a lack in testing devices for damper characteristics. An automatic testing system for the parameters of torsional vibration dampers on engine crankshafts is presented. Based on the sinusoidal scanning, a process of 'testing-data analysis-test report' is automatically achieved. Compared with the B&K testing system, the new system can provide the characteristic parameters of crankshaft torsional vibration damper more accurately.
