Parameter Weight Analysis of Car Side Impact Accident Reconstruction

Chong Li
In order to improve the accuracy of car side collision accident reconstruction, a domestic accident case is taken as an example to reconstruct the accident through PC-CRASH and design the orthogonal experiment. Through experiments, the weight ranking of PC-CRASH side impact reconstruction is obtained. According to the weight of the parameters, the accident case is reconstructed again. The results show that th

Optimization of AEB Key Parameters in Car to Electric-Two-Wheeler Accidents

苏敏 汤
In order to determine the optimal value of key parameters of automatic emergency braking (AEB) system, an optimization method based on real accident simulation is proposed. Accident reconstruction of 65 car to electric-two-wheeler collision accidents was carried out by using PC-Crash. According to the different parameter values of AEB system radar, the virtual accident reconstruction results are obtained. The optimal value of key

Gas Condensate Wells Simulation to Optimize Well Flow Performance Using Tubing Equations Coupled with Inflow-Performance-Relation (IPR) Curve

Ahmadreza Ejraei Bakyani, Alireza Rasti, Sajjad Qazvini, Feridun Esmaeilzadeh
Wells performance is evaluated by IPR curves that show the relationship between bottomhole pressure and inflow rate. This curve and its outcome equation can be applied for production schedule and maintenance management of well and reservoir. But, the measuring of bottomhole pressure to approach these curves needs much time and high expenses and also running special tools in wells. In these operations, the probability of catastroph
