A clustering algorithm named “Clustering by fast search and find of density peaks” is for finding the centers of clusters quickly. Its accuracy excessively depended on the threshold, and no efficient way was given to select its suitable value, i.e., the value was suggested be estimated on the basis of empirical experience. A new way is proposed to automatically extract the optimal value of threshold...
Landmine and improvised explosive (IED) are the major threat to the occupants inside armored vehicles. IED-detonation introduced Global effects of severe acceleration can greatly hurt vehicle occupants. To investigate the responses of armored vehicle and its occupants subjected to landmine explosion, an low-cost equivalent miniature model of the vehicle replacing real-scale one was built. With a full...
The purpose of this paper is to study the remove insurance time with different stiffness of typical MEMS S&A (Safety and Arming)device, which are composed of the micro spring, slider, zigzag slot and card lock. According to higher dynamics theory, the zigzag slot collision energy loss, card lock closure features such as abstract the slider in the theoretical model of motion process, we used MATLAB...
In this paper, a MEMS S&A device has been proposed. The size of the device is φ 12×0.3mm. The role of the centrifugal insurance mechanism is to ensure the safety in handling transportation and storage, and reliable firing with the launch overload. Through establishing the three-dimensional model of the centrifugal insurance mechanism, establishing the force and the parameters of the centrifugal...
In this paper, aiming at the failure mode with MEMS spring fracture of MEMS S&A (Safety and Arming) device, the dynamic simulation and response surface method are combined to use to establish the relationship between the structure response and the structure random variables. The stress values are fitted by the least square method, and the binary quadratic equation, whose variables are the MEMS...
