vibration fatigue test

Research on vibration environment test technology of aircraft structure combined with fatigue or static load

飞机结构件复合加载振动环境试验技术研究

The design mainly involves the analysis of the stress, fatigue, thermal ratchet and fracture mechanics, the analysis of flow-induced vibration of the internals and the test verification.

主要涉及的内容包含每个设备部件的应力、疲劳、热棘轮、断裂力学分析和内部构件流致振动分析以及试验验证等。

Vibration fatigue test of tractor cab

拖拉机驾驶室振动疲劳试验研究

Analysis and experiment for accelerating vibration test of car fuel assembly are carried out on base of Miner's linear accumulated fatigue damage theory.

应用Miner线性累积损伤理论，对汽车燃油分配管加速振动试验进行分析和试验。

Load, frequency and cycle number are three key parameters of a vibration fatigue test. It is hoped that they are stable and can be adjusted steplessly.

载荷、频率和循环数是振动疲劳试验中的关键参数，既要能无级可调又要稳定。
