The unit load had large fluctuation when valve movement test was performed at 400 MW during the commissioning of unit 3 in Tuoketuo Power Plant,and when CV1 test ended,we could not open the valve and had to shutdown the unit.
The expression for the relation between the deform and the external force of progressive rate springs with variable arm length was established by using unit load method, and then the non-linear dynamics equations was given.
In this paper, Based on finite element inverse analysis and the least square method, a method is proposed to identify the magnitude and location of the undefinite load applied on the piezoelectric smart structure. The method chooses the piezoelectric responsive charge as fitting parameter in the object function. The initial load is determined by the unit load pre-approched method.
Briefly deals with the importance of checking the deformation conditions in moment distribution. Introduces and comments three check methods, and suggests that the unit load method to check the result of moment distribution in design would be used.
According to the general method to calculate the load capacity of involute cylindrical gears in GB 3480--83, it is necessary to calculate the relative deflection fsho in the tooth wide direction of gears which are loaded with one unit load.
Applying energy method principle,through a method of virtual supposing a moving load or unit load,the displacement equation of structure can be obtained by using A. Castigliano theorem or Moore integral.
By means of CAD, FEM and multi-body system dynamics method (MBSDS), and through numerical simulation calculations,the distribution of stresses and strains of metro vehicle bogie frame is deducted at unit load under the virtual environment of computer.
The economy index of annual cost for unit load and the reliability index of ASAI are adopted and quantified for the combination power system to study their trends by the change of load density and substation capacity. Different connection modes in the same condition are compared.
Last, a concept of unit load stress matrix is put forward.
The use of Cor-93 as a constructional material for large ceramic parts for a service temperature up to 1200°C and absorbing a unit load up to 150 MPa is recommended.
Results are given of an X-ray investigation of the formation of a textured surface layer on polytetrafluorethylene (PTFE) film and its dependence on external mechanical factors - unit load and sliding speed.
The influence of unit load on wear resistance of the white layer
Equations correlating permeability coefficient and unit load have been derived.
