As is well-known that the traditional semiempirical structure design method based on safety coefficients is phasing out because it can’t reflects the structure reliability with quantity, and the structure reliability design method based on the probability and statistics theories is applied widely by engineering designers. According to the above thoughts, the truss structure shape optimization design method based on the reliability is put forward. Firstly, the truss structure reliability calculation mathematical model is established by the improved first-order second-moment method. Secondly, the truss structure shape optimization design model is built on the condition of the reliability constraint. At last, the stress entropy improved chaotic particle swarm optimization algorithm is come up to solve the above model. The example of A 25-bar truss shape optimization design shows that the proposed model and algorithm in this paper is more reasonable than others and it can provide the reference about theory and application for the practical engineering structure shape optimization design.

Outlet flame trap is a kind of safety device, which can quenche flammable gas and reduce gas temperature in exhaust system for flameproof diesel engine. However, its installation increases exhaust system resistance， and influences performance and fuel economy of flameproof diesel engine. In order to decrease pressure loss, three dimensional model of outlet flame trap is established by using UG software. Then, with the applying of FLUENT software, CFD simulation of outlet flame trap is conducted. Moreover, this paper analyzed research that compared long square tube outlet flame trap and short square tube outlet flame trap. According to the simulation results, when gas flowing through outlet flame trap, since cross section suddenly changes between the imported segment and import square tube，the maximum pressure drop exists in the location of the fence segment, and the low pressure region exists in the import square tube sides. Low pressure region located in the square tube makes gas flow reverse, forms swirl, and weakens pressure drop. Long square cube outlet flame trap can reduce the intensity of swirl, decrease gas loss, enhance stability of flow field, and improve exhaust performance of outlet flame trap in flameproof diesel engine.
