Both motor car and each trailer of HST were modeled as a multi-rigid-body system with two suspensions, and LVT was modeled as an assembly of track segment elements with 24 degrees of freedom. The vertical vibration matrix equation of the system was established on the basis of the principle of the total potential energy with stationary value in elastic system dynamics and the rule of "set-in-right-position" for formulating system matrixes, and then Wilson-θ numerical integration method was used to solve the problem. The dynamic responses of the system were calculated when the train runs at the speed of 200 km/h. And the effects of vertical stiffness of rail fastener and block pad on vertical vibration responses of the system were investigated.

When researching the producer's behavior,such as factor input and output efficiency,using product function or cost function,researchers frequently ignore the economic inefficiency and assume that the productor can attain the production possibility frontier.

通常采用生产函数或成本函数研究生产者行为时，一般默认生产者总是在生产可能性边界安排生产，而忽略了由于产出的经济无效率所造成的偏差，这种偏差最终会影响要素替代弹性、要素最优配置及产出效率的准确测度。本文采用面板模型的三要素成本函数循环参数估计法，通过施加规模报酬不变的假设，估算了辽宁省工业部门二类行业的相对技术无效率、配置无效率程度及要素间的相对价格扭曲，并计算了资本、劳动、能源要素间的交叉替代弹性。

Based on rail/wheel reaction and track/bride reaction theory and systems engineering theory, new vehicle-track and vehicle-track-bridge system dynamic models are established and discussed in details, including ballast track model and ballastless track model. The characteristics of the models are:(1) vehicle-track and vehicle-track-bridge system dynamic models are coupled in vertical and lateral;(2) track vibration on bridge is taken in account, track on bridge is considered as one or two layer continuous-point supported rail model, according to actual track structure, interaction between vehicle and bridge transfer from track structure;(3) three type of ballastless track models (tieembanked, elastic-tie-block, slab track) are presented;(4) models reflect the main feature of actual vehicle, track and bridge structure, the response computation frequency of models is relatively broad, which can be applied to analyze both low frequency and high frequency vibration.
