摘  要:
通过设计的金属干摩擦特性试验装置,测量得到了金属材料试件在固定正压力下的干摩擦迟滞特性,并且在MSC/MARC中建立了与试验相一致的有限元模型来仿真预测干摩擦接触的粘-滑迟滞特性。通过与试验数据的比较,验证了仿真模型的正确性,发现有限元模型结果与试验结果以及理论计算结果吻合程度较好,从而有助于分析工程实际中材料干摩擦特性和阻尼特性,验证了有限元方法的可行性。

摘  要:
A test apparatus of metal's dry friction characteristic was built to measure the dry friction hysteresis characteristic curve of metallic material specimens under given normal force.A corresponding MSC/MARC finite element model is developed to simulate the friction stick-slip hysteresis characteristic of contact dry friction for any prescribed quasistatic load cycle.Comparisons of test data and simulation data demonstrate the accuracy of the FEM model.The simulation result is consistent with the test and theory data which can help analyzing the material's dry friction characteristic of real project and provide the reliable computation for the NVH simulation of engine.
