密闭爆发器容积弹性增量的计算及对测试结果的修正

Calculation on the Elastic Increment of Closed Bomb's Chamber Capacity and Correction on the Testing Results

利用 CAD技术 ,对密闭爆发器壳体在测试中的弹性变形作出精确计算 ,得到了药室容积在受压情况下的实际弹性增量 ,以此修正由其体积的变化带来的测试误差 。

Using the technology of CAD, the elastic deformation of closed bomb for propella nt is calculated accurately in the test, the actual elastic increment of chamber capacity under pressure is gained. Through the research the testing error due t o the changing of cubage is corrected and the testing accuracy is improved.
