Development of aerospace technology is inseparable from the excellent performances of guidance system. It often tests performances of guidance system on simulator in engineering. It can be drawn that coupling effect among the rotary axes in simulator is present by analyzing mathematical models of simulator. Currently, experimental study carried out for the conclusion about coupling effect among the rotary axes is a few. Therefore, experimental study about coupling effect among the axes at the time of simulator linkage is carried out to determine the existence of such a coupling effect and observe its impact.

Theoretical Results

The mechanical behavior of multi-cracks under compression has become a very important project in the field of fracture mechanics and rock mechanics. In this paper, based on the previous theoretical results of the failure criterion for brittle materials under compression, experiment study is implemented. The specimens are square plates and are made of cement, sand and water, and the cracks are made by using a very thin film (0.1 mm). The relations of material compressive strength versus crack spacing and the lateral confining stress are obtained from experimental results. The experimental results agree well with the failure criterion for brittle materials under compression, which indicates that the criterion is effective and applicable.

Response of sand dune when overwashed by tsunami or storm surge, is investigated by conducting small scale laboratory study. Dune consisting of initially wet sand and initially dry sand are tested for three different sand grain sizes. Overtopping of water and the corresponding sediment transport are analyzed. These data set can be used to validate mathematical models associated with dune sediment transport as well as prediction of dune profile.
