Millions in the world suffering diabetes mellitus depends on insulin therapy to control their blood glucose level daily. However, the painful daily injections they need to take could lead to other complications if it is not done correctly. To date, it is suggested by many researchers and medical doctors that the needles should be inserted at any angles of 90º or 45º. Nevertheless, this recommendation has not been supported by clinical or biomechanical evaluation. Hence, this study evaluates the needle insertion for insulin therapy to find the favourable angles in order to reduce injury and pain onto the skin. Finite element analysis was done by  simulating the injection of three-dimensional (3D) needle model into a 3D skin model. The insertions were simulated at two different angles, which are 45ºand 90º with two different lengths of needles; 4 mm and 6 mm. This study concluded the favourable angle for 4 mm needle to be 90º while 6 mm needle was best to be inserted at 45º as these angles exerted the least maximum stress and strain onto the skin.

Y-Type rolling mill with three roller is a new kind of wire mill.The three-dimensional models of rolling are established by Pro/E. Based on the finite element analysis software ANSYS/LS-DYNA, the rolling process of wire by Y-type rollers is simulated. The rolling piece movement is analysed. Stress and strain of Y-type roller are also analysed.

The paper is to study the working device of rough terrain forklift, carried out forces analysis on a typical three section telescopic boom, results indicated that the boom working in the lowest position is the most dangerous situation, Adopted the CAD software of SolidWorks to build the three dimensional models of telescopic boom, then used the FEA component of SolidWorks Simulation to carried out finite element analysis(FEA) for the working device, obtained FEA results. By the use of comparing the stress testing results with the finite element analysis results, certificated that the finite element analysis models are reasonable and the finite element method by Simulation is feasible and reliable. All of these works have very important reference value for designing and optimization of the telehandler in the future.

Three dimensional models and finite element models of conductor clamps are built in software Solidworks and Abaqus. Different forces are loaded on finite element model of conductor clamps to obtain distributions of stress and displacement. Optimal design of conductor clamps is performed with finite element analysis and field test data. The results show that optimal design scheme achieves optimal target.
