In this work, the topology optimization of a mortar base plate is analysed under impact loading conditions. Usually, in case, only ordinary volume constraints considered. However, to reduce quality and facilitate engineering applications, topological problem continuum constraint A finite element model has been established verified by testing for plate. The variable density method was used obtai...

Abstract Flexure oscillators are promising time bases, thanks to their high quality factor and monolithic design compatible with microfabrication. In mechanical watchmaking, they could advantageously replace the traditional balance hairspring oscillator, leading improvements in timekeeping accuracy, autonomy, assembly. As MEMS oscillators, performance can rival that of well-established quartz o...
