The invention relates to the technical field of automobile safety, and provides a seat whiplash injury resistance optimization method based on test and simulation, and the method comprises the steps: firstly, through the comparative analysis of finite element simulation and whiplash test results of a seat, identifying main factors influencing whiplash injury, including design variables such as the thickness of a headrest rod and the thickness of a seat backrest supporting tube; sample points required by optimization are collected by using a Harmersley test design method, and an accurate approximation model is established through a radial basis function neural network (RBF). On the basis, a multi-objective genetic algorithm is adopted to carry out multi-objective optimization on seat design variables, and the purpose is to reduce the neck injury index (NIC) and the upper neck tension. The optimized design parameters effectively reduce the neck injury index and the upper neck tension, and the whiplash injury resistance of the seat is further improved. Through simulation verification, the error between the optimization result and the approximation model is controlled within a reasonable range, and the effectiveness and feasibility of the optimization design are verified.

The invention relates to the technical field of collision testing, in particular to a passenger injury prediction method and device suitable for a large-angle seat. The method comprises the following steps: acquiring a relative spatial position change curve of a passenger and a safety belt fixing point through a machine vision technology in a whole vehicle collision test; inputting the relative spatial position change curve into a passenger injury prediction model to obtain a passenger head acceleration time sequence curve and a neck axial tensile force and bending moment time sequence curve; according to the passenger head acceleration time sequence curve and the neck axial drawing force and bending moment time sequence curve, a passenger head injury index and a neck injury index are calculated. According to the method, passenger injury prediction in the collision process is achieved with low calculation cost, and a passenger injury prediction model which is low in cost, high in efficiency and high in precision is formed.

The invention relates to the field of neurological rehabilitation medicine, and particularly discloses application of task-oriented training in promoting functional recovery after spinal cord injury (SCI). The invention is based on the discovery that task-oriented training (such as single globule grasping training) can activate an NRG1 / ErbB4 signaling pathway by up-regulating the phosphorylation level of neuro-regulatory protein-1 (NRG1) and a receptor ErbB4 of the NRG1, thereby promoting regenerative cortical spinal bundle (CST) axons and spinal motor neurons to form functional excitatory synapses and inducing the conversion of synaptic phenotypes to excitatory. The invention provides a treatment method including task-oriented training and a combined strategy for combined application of the treatment method and a treatment method for activating endogenous axon regeneration capacity (such as by inhibiting PTEN expression), the treatment method is used for improving upper limb movement dysfunction after spinal cord injury, particularly after neck injury, and a new scheme is provided for clinical treatment.
