摘要
主要根据拉、压不同模量弹性力学理论,采用空间轴对称体有限元法,对多脉冲发动机的陶瓷盖板结构进行了应力分析。根据发动机的工作特点,在应力分析中考虑了动力响应的问题。为了得到符合工作要求的较为理想的陶瓷盖板结构形式,研究了盖板形状、尺寸大小、支承条件对应力分布的影响。
According to the elastic theory with different tensile and compressive modulus, the stress distribution of the ceramic coverplate in multipulse motor with finite element method for axisymmetrical configuration, and with consideration of the effect of dynamic load is analyzed. In addition, to obtain the perfect structure of ceramic coverplate, the stress distributions in different shape, dimension and boundary conditions are calculated.
