多轴动态加速度试验夹具设计方法研究

Fixture Design Method for Multiaxial Dynamic Acceleration Test

目的针对多轴动态加速度试验的特点探索一种适合多轴动态加速度试验的夹具设计新方法。方法分别采用传统经验设计法和新方法对同一简单模型进行力学仿真分析,并进一步对比两种方法所得结果的差异。结果新方法所得结果更具全面性,在多轴动态加速度试验过程中更有利于保证夹具的安全性,适合推广应用。结论多轴动态加速度试验与传统的单一稳态加速度试验差异较大,在相应夹具设计时更应该注重试验的全过程。

Objective To explore a new method for the fixture design suitable the test according to the characteristics of multiaxial dynamic acceleration test. Methods The traditional experiential design method and the new method were applied to the mechanic simulation analysis of the same simple model, and the differences in the results by the two methods were compared. Results In the process of multiaxial dynamic acceleration test, the new method could achieve more comprehensive results and guarantee the safety of the fixture, which was suitable for popularization and application. Conclusion There is a big difference between the multiaxial dynamic acceleration test and the traditional single static acceleration test, the whole process of the test should be concerned in the corresponding fixture design.
