Abstract

Pendulum-based rebound resilience measurement is a well-established method for characterizing the energy absorption of elastomers. However, existing standards are limited to elastomers with a hardness range of Shore A30 to A85 and polymeric foams, providing only a single value of rebound resilience without further investigations into material behavior during impact. This study extends the application of this method to a broader hardness range (Shore 00–30 to D50) and enhances the analysis with advanced instrumentation, including a piezoelectric load cell, an angular transducer, and a high-speed camera, which enables capturing the impact duration, impact force, specimen compression, and the determining of elastic energy during the impact.

先进的仪器基于摆回弹测量方法表征弹性体的冲击动力学

基于摆法的回弹弹性测量是表征弹性体能量吸收的一种行之有效的方法。然而，现有的标准仅限于硬度范围为Shore A30至A85的弹性体和聚合物泡沫，仅提供单一的回弹弹性值，而没有进一步研究材料在冲击过程中的行为。本研究将该方法的应用范围扩展到更广泛的硬度范围（Shore 00-30至D50），并使用先进的仪器加强分析，包括压电测压元件，角传感器和高速摄像机，可以捕捉冲击持续时间，冲击力，试样压缩，并确定冲击过程中的弹性能。

期刊介绍： Polymer Testing focuses on the testing, analysis and characterization of polymer materials, including both synthetic and natural or biobased polymers. Novel testing methods and the testing of novel polymeric materials in bulk, solution and dispersion is covered. In addition, we welcome the submission of the testing of polymeric materials for a wide range of applications and industrial products as well as nanoscale characterization. The scope includes but is not limited to the following main topics: Novel testing methods and Chemical analysis • mechanical, thermal, electrical, chemical, imaging, spectroscopy, scattering and rheology Physical properties and behaviour of novel polymer systems • nanoscale properties, morphology, transport properties Degradation and recycling of polymeric materials when combined with novel testing or characterization methods • degradation, biodegradation, ageing and fire retardancy Modelling and Simulation work will be only considered when it is linked to new or previously published experimental results.
