Analysis of Braking Characteristic of Parachute Gear

A brief introduction of the parachute gear system,viewing the brake cable wire as continuum structure,the vibration controlling equation of system was established based on Newton's laws.In finite element software ANSYS,use lumped mass element to simulate self weight and load of cage,use plastic property of LINK180 element to simulate buffering effect of bumper and use elastic property of LINK180 element to simulate the brake cable wire.Through simulation of actual conditions,get the dynamics characteristic of system during braking of parachute gear finally.
