拉普拉斯变换法 meaning in English
method of laplace transform
Examples
- Then , taking into account the effect of the compression of the approach roadway and the differential slope of the bridge slab , the author analyzes the dynamic response of man - vehicle - road system when the vehicle approaches and leaves the bridge by means of laplace transform , the curve of man ' s acceleration versus time , the vertical force between the vehicle and road versus time , the man ' s maximum transient vibration value and the maximum force between the vehicle and road are got , and the program about the calculating progress above are edited . based on the analysis above , the influence on the maximum transient vibration value of some parameters about the vehicle and road such as the movement direction and speed and weight of the vehicle , the differential slope of the bridge slab and the length of the approach slab , are studied , and some conclusion are given
分上桥和下桥两种情况，考虑车路耦合和桥面沉降坡差的影响，对车辆通过设和不设搭板的路桥过渡段时“人?车?路”系统的相互作用用拉普拉斯变换法进行了动力响应分析，得到了人的加速度及路面对车的垂直作用力随时间的变化曲线、人的加速度最大瞬态振动值和路面对车的最大作用力，分析了车辆的行进方向、速度和载重，桥面沉降坡差和搭板长度等车和路各参数对计算结果的影响，并编制了相应的计算程序。 - Considering that a hollow circular chimney composed of the multi - layers of fire - resistant , heat insulation and reinforced concrete and that low temperature chimney has short term super - high temperature phenomena , one - dimension transient physical model and mathematical model were established by using laplace transform method , with formula of transient temperature concluded
