3、proof starter shell can effectively under internal explosion pressure, can avoid high temperature internal explosion caused by the explosion of exterior explosive environment. Flameproof starter shell body is composed of

4、 two different rectangular, it first makes structure is simplified, the removal of non key parts of simplified, leaving the outer panel and the key force bearing component. The elastic and plastic mechanics is introduced

5、 into the design process, according to the shape size, the shell plate is simplified as a mechanical model, combined with the small disturbance theory, calculate the theoretical size of each panel; by comparison, accordi

6、ng to the theory and the real draw up plans of different plate thickness, using reinforced reinforcement on the panel;Two pairs of flanges on flameproof boxes and wiring chamber to meet stiffness requirements, the formul

7、a for calculating the size of the flange derivation, And obtained the results; Theoretical stress analysis the bearing on other key components, such as bolts. Analysis of the actual situation of the test and force the st

8、arter to determine the test load strength analysis, refer to the relevant standards and information presented launcher shell deformation allowable value.Three dimensional modeling of starter using UG 3D modeling software

9、, the solid model of the key force bearing components were made and simplified model. Use Workbench software startup shell finite element analysis. Efficacy of displacement and stress in the housing and parts produced un

10、der the test pressure 1MPa. Get key parts of the flameproof enclosure, doors and flange stress,According to the theory of value, to improves components of stress analysis on the starter casing and key, so as to improve t
