DMA Dynamic Viscoelasticity Measurement Technical Document for Sports Equipment

A double-drive DMA viscoelastic device that evaluates the durability of sports equipment.

In the sports equipment industry, the durability of products is highly valued. Especially for products exposed to impacts and friction, accurately understanding the viscoelastic properties of materials is essential for improving product quality. Inappropriate material selection or design can lead to early deterioration or damage of the product. Our DMA dynamic viscoelastic measurement device achieves high load performance and high-precision measurements through a double drive system, strongly supporting the durability evaluation of sports equipment. 【Usage Scenarios】 * Material evaluation of sports equipment such as rackets, balls, and shoes * Evaluation of shock absorption, abrasion resistance, and fatigue resistance * Optimization of material selection in product design 【Benefits of Implementation】 * Improved product durability * Reduced product development time * Enhanced efficiency in quality control

Applications/Examples of results

Dynamic viscoelastic data, which is essential for product development, is highly dependent on "strain" and "stress." Data obtained under conditions different from actual usage does not accurately reflect the material properties in product development. The "Double Drive" system controls dynamic and static loads with two independent motors, providing dynamic displacements of ±0.01μm to ±6.000mm and dynamic loads of ±0.01N to ±500N (with higher models up to ±4000N). Additionally, static displacements of up to 60mm and static loads of up to 1500N can be applied through individual motors. This allows for the reproduction of the actual loads that products experience, accommodating a variety of materials including rubber, resin, carbon (CFRP, CFRTP), film, metal, ceramics, and glass. Product lineup: ◎ 1500℃ Temperature Control HT Series ◎ Standard Type 25N–500N Series ◎ High Load Type 2000N–6000N Series ◎ Flexometer GABOMETER 2000N/4000N
