Abstract

Inspired by the biomechanical mechanism of locust jumping

an ejection device with joint torsion spring and double trapezoidal structure is designed

which has the ability to achieve large ejection stroke for low thrust demand and keeps the characteristics of initial bow angular velocity and angle during missile separation. The efficient mechanism layout parameters are optimized by the optimization methods based on parameterized models and Kriging surrogate models. The influence of arm flexibility effect on missile ejection separation parameters during launch is studied based on a rigid-flexible coupling dynamic model. The projectile-machine

separation process is investigated based on computational fluid dynamics. The research results indicate that the optimization method based on parameterized models and Kriging surrogate models can be used to quickly obtain the mechanism parameters that meet the design requirements. In the process of ejection

the flexible deformation of middle arm will lead to the difference between the actual separation parameters and the ideal design parameters. The flexible effect cannot be ignored in the detail optimization design

and the structural stiffness should be increased to reduce the design deviation. The given design example can meet the design criteria and the missile can be safely separated

proving the effectiveness of the new design in this paper.

At the moment of ejection, a great impact load is generated on the upper frame and air inlet. The ejection impact loads of embedded missile bay should be accurately calculated for structural design. A dynamic model of missile ejection mechanism is established. The influence of connection form of hanging point on the impact load is obtained through the rigid or flexible treatment of the hanging point of embedded missile bay. The relationship between peak output and impact load characteristics of different actuators is studied. The influence of the mass of a missile on the impact load after retrofitting the ejection frame is analyzed. The research results show that the flexible connection form can correctly describe the transfer process of impact load. And the peak pre-power mode can provide better ejection effect. The task envelope of the modified ejection system can be guided from the relationship between the mass of missile and the peak value of power. Key
