Abstract: A new loading test self-balanced loading test is introduced in this paper. Compared with the traditional loading test, its test principles and load transfer theory are presented. Based on the results of the contrast experiments of two methods, the conversion method from the results of self-balanced test to the results of traditional loading test is put forward.

Abstract: With the continuous development of large-scale integrated circuit technology, the importance of structural testing and testability design for digital logic circuit has become increasingly evident. In the testing domain, Bench is the most commonly used formats to describe a measured circuit. In order to test the measured circuit using computer, files with various formats must be converted to a netlist file which can be identified by computer. Lev format is a common netlist file. This paper mainly discusses how to convert the Bench file into Lev file, and it is proved by testing program correctness and robustness.

Abstract: The rigidity-step-change method is set up by Mechanics of Materials. Its distinguishing feature is at the steps of solving the deformation problem. It changes a deformation body to a rigid body before the solution of deformation of the body is get which fitting together with another. Then, step by step, it gets answer by Superposition Method. The main content of Conversion Method is at which the elastic axial line of the conversion beam substitutes the beam which being conversed. And the solution of deformation of the conversion beam could be found easily. In solving the elastic statically determinate frame, it uses the rigidity-step-change method and Conversion Method at suitable steps. It has good qualities for finding solution of the slope of the frame with simple support beam. Only primary computation is need. The steps of solution of the frame slope are given by an instance.

Abstract: Owing to lack of geometric method for calculating frames with the shape of T, the conversion method is used to resolve the frames in which no joint has lateral displacement. It puts forward the analysis steps of the solution of the frame. The concrete process of calculation belongs to primary computation of algebraic equation. It gets analytic solution. The calculation sequence of an example of a frame is advanced.

Abstract: Owing to lack of geometric method for calculating frames without forces in one direction, the conversion method is used to resolve the slope of the frames in which no joint has lateral displacement as no force in this direction. It puts forward the twins equations of the displacement and the analysis steps of the solution of the frame. The concrete process of calculation belongs to primary computation of algebraic equation. It gets analytic solution. The calculation sequence of an example of a frame is advanced.

Abstract: Acceleration time, as an important dynamic performance index of an automobile, is classified as acceleration time of shift and acceleration time at a given gear to evaluate an automobile’s acceleration performance. Compared with the traditional calculation method, this proposed algorithm calculates an automobile’s speed of optimal-power shift by using linear interpolation; calculates the acceleration time using Gauss integral, and calculates the acceleration time to a given distance by combining conversion method and interpolation method. A numerical example is given and the actual test results indicate that this algorithm is fit for automobile design.

Abstract: The influence of methods for converting torsion data (torque, number of turns and speed rotation) into equivalent variables (true stress, true strain and true strain rate) on the Garofalo equation parameters is studied. Torsion tests for a high strength low alloy steel at temperatures in the range 900 to 1150°C and strain rates in the range 0.5 to 30 s-1 were conducted. The flow behavior of the material was analyzed by means of the Garofalo equation which is especially adequate for the correlation of torsion data in wide ranges of temperatures and strain rates. The Garofalo equation was fitted at different strains: from peak strain to a value of strain where a steady-state is assumed. The parameters of this equation, A, Q, n, , were determined by the RCR method which does not need initial values and provides coefficients indicating the quality of the fitting. Finally, the Garofalo equation parameters were related to creep mechanisms operating in this steel.
