日本日立公司开发出了可再现大型机械结构件疲劳现象的3轴试验装置,可用于实现部件材料、尺寸,以及结构的最优化。该装置配备可在0°、45°、90°方向对试验片材加载负荷致动器并将试验片材单侧固定的夹具,通过分别从3个方向向试验片材施加独立的负载,在试验片材上再现实际机械结构件运转时产生的复杂的受力情况。据介绍,3轴中的45°轴为固定
Hitachi Ltd. has developed a 3-axis test set-up that reproduces the fatigue of large mechanical structures that can be used to optimize part materials, dimensions, and structures. This device is equipped with a jig that can apply a load actuator to a test specimen in a direction of 0 °, 45 °, and 90 ° and fix the test specimen on one side by applying independent loads to the test specimen in three directions. The test sheet reproduces the complex forces that occur when the actual mechanical structure is in operation. According to reports, the 45 ° axis in the 3 axis is fixed
