A multiplepoint to surface flexible contact model was developed to describe the deformation of contact area, microslip phenomena and effects of dry friction between the soft bottom of shoes and hard ground. Force constraints instead of unilateral geometry constraints were used to develop a set of secondorder ordinary differential equations of the dynamics for a 15 degree of freedom rigidbody human model to study various human motions. A jumpping movement was numerically simulated to study the reaction force between the shoes and the ground with different model parameters. The results show that the reaction is complicated and more careful study is needed. This work provides an efficient method to study human body dynamics with ground contact.

AIM:To study the characteristics of human body dynamics response and injury induced by+Gx &+Gz high acceleration landing impact. METHODS:Using Hybrid III dummy to put in the backing cabin of space,experiments on landing impact of all levels were carried out and related data were analyzed. RESULTS:Experimental data showed good consistency.The injury values of head,neck,thorax and vertebra respectively showed good orderliness quadratic function(R2 >0.9) and increased with 6-30 g input accelerations.Using different guideline,injury factors were analyzed to obtain the damage degree of different parts of human bodies. CONCLUSION: The regular patterns of dynamic response to injuries of head,neck,thorax and vertebra are dissimilar.It is necessary to focus on high injury sensitivity bodies for studying injury regular pattern and protection principle at high G landing impact conditions.
