摘要
本文考虑到在冲撞过程中汽车和护栏共同变形的影响,建立了汽车-钢筋混凝土护栏的连续系统的计算模型,用Runge-Kutta法求解运动方程,由计算机仿真模拟汽车冲撞护栏的全过程,给出了汽车运行轨迹、车体转角、减加速度以及护栏受到的冲击力等值.
The dynamic model of vehicle-reinforced concrete guardrail system considering the deformation of both vehicle and guardrail is developed in this paper and Runge-Kutta method is used to solve the dynamic equations.The simulation program is coded on microcomputer and is used to simulate the whole process of vehicle impacting on reinforced concrete guardrail. The vehicle responses such as displacement, acceleration, etc. and the vehicle impact forces acting on the guardrail are also given in this paper.
