%X Dynamic equilibrium is critical aspect of fruit quality and ripeness. Dynamic equilibrium is determined according to sinusoid stress-strain. Pear fruit makes marked effects on dynamic modulus and phase position in different pre-load, active power and ripeness. Test shows that in same frequency pre-load makes modulus of elasticity increase, least mature Huanghua pears have smaller phase position and bigger modulus of elasticity than ripe ones.
