Dropping Damage Evaluation for Critical Components of Tilted Support Systems
摘要
Abstract
Dimensionless dropping shock dynamic equations of tilted support spring system with critical components are established and solved by adopting 4th order Runge-Kutta method. The system parameter, initial velocity of the dropping shock and the angle of support, the frequency ratio or the damping ratio are regarded as basic parameters and the dropping damage boundary of the critical components is obtained. The influences of the support angle, frequency ratio and damping ratio of the system on the dropping damage boundary of the critical components are analyzed. Results of evaluation demonstrate that decreasing the angle or increasing the frequency ratio are beneficial for expending the safe zone of the critical components; the optimal damping ratio of the system exists, and reasonably choosing the damping ratio can improve the anti-shock property of the tilted support spring system; in order to obtain ideal vibration reduction and dropping shock resistance characteristics for the tilted support spring system, effects of the stiffness coefficient of the products, the original length of the spring and relevant parameters need to be considered comprehensively.关键词
