In this thesis, finite element analysis was performed on the V-shaped expansion joint with different sidewall angles to investigate its load-carrying and deformation compensation abilities with the purpose of promoting the application and standardization of this kind of expansion joint.

Based on the simulation of radial deformation of plunger couple of high pressure fuel injection pump used for common rail system,seven kinds of plunger couples were designed by using deformation compensation technology.

Structural optimization in line with the principle of deformation compensation is therefore conducted on base of the coupling effects contour plots,which is proved to be quite effective by compariso.

Based on the above, it researched the deformation compensation of the bracket .

Effects of compensation capacity and palatability on the dominance of plant species in grazing community;

Finally we introduce the concept in figure of merit of microware field to quantize the compensation capacity of the dispersion compensator.

Accroding to the structure characteristics and using request of the hanger, analyzed the press process, through using hole deformation compensation method, determined an efficient process plan and component blank size, designed the practical die structure, satisfied the component using request, reduced the cost.

Application of precompensation for deformation in diminishing the deformation of injection moulded products;
