Ball bearings are used in vast majority of mechanisms for space applications (such as Solar Array Drive Mechanisms, pointing mechanisms or reaction wheels) in order to provide low friction and smooth motion between parts. These applications differ from the ground ones due to space ... Per saperne di più
Using the Solid Mechanics interface, a model is set up to investigate the impact of static stress on a bicycle chain for different geometries related to three chain generations. A contact model is used to induce the stress. Plastic deformation is taken into account. Based on the ... Per saperne di più
针对某机床动态性能不足，对整机进行结构优化，首先需要建立准确、高效的机床有限元动力学模型。借助COMSOL软件中的Solid Mechanics模块和Optimization模块可以很好地完成机床的建模仿真。 据文献统计，60%-80%的刚度、90%左右的阻尼由各种结合部决定。因此建立机床动力学模型的难点在于确立结合部的特性。首先需要进行机床的模态试验，得到整机的固有频率和模态阻尼比等参数。利用Solid Mechanics模块进行机床的动力学建模，将整机的结合部简化为8个，添加一致对来模拟各个结合部，并给定初始的弹簧基础的刚度值Ki ... Per saperne di più
In this work the effective elastic properties of a SU8 photoresist matrix reinforced with ZnO nanomaterial (in the form of cylindrical nanowires, spherical and ellipsoidal particles) have been evaluated employing COMSOL Multiphysics® software. The Solid Mechanics physics interface of ... Per saperne di più
When treating fractures of the accessory carpal bones in horses, it is important to understand the forces that implants (screws and plates) must withstand. The etiology of the fracture is not fully understood, but their high incidence during exercise suggests a relation to biomechanical ... Per saperne di più
Advanced Gas Cooled Reactors (AGRs), owned and operated by EDF Energy, generate around 15% of electrical power in the UK. As AGRs approach their end of life, cracking is liable to occur in the graphite bricks which make up a major part of the reactor core. Safety cases to justify ... Per saperne di più
Polymer–metal is a kind of new composite materials rather than traditional metal packaging materials. It has both features of polymer film and sheet metal. However, the polymer film will damage in the sheet metal forming process. Therefore, we try to established a sheet metal forming ... Per saperne di più
Focused ultrasounds are used in many medical applications as a treatment: it is important to evaluate the induced effects of such a procedure to achieve a high accuracy while keeping the untargeted surrounding areas safe. In the present paper, COMSOL Multiphysics®, a simulation software ... Per saperne di più
The semiconductor industry is always looking for early anticipation of manufacturing risk, pushing the development of Computer Aided Engineering (CAE) modeling of processes. Robust Chip-Package Interaction requires a deep understanding of thermo-mechanical stresses imposed during the ... Per saperne di più
In solid mechanics, there is considerable interest in achieving “invisibility”. The applications in mechanics include protection of structures and parts of structures from potentially harmful transient waves and steady state vibrations. A suggested large scale application is that ... Per saperne di più
