According to this device, there is no need to oscillate the object with a high frequency band and there is no need to enhance the stiffness of the housing of the measurement device, which leads to a downsizing of the device. Further, there is no need for measuring of acceleration speed of the object to be measured and accelerator can be eliminated to reduce the cost of the stiffness measurement device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Stiffness measurement method and device","description":"A calculating device of the stiffness measurement device pressurizes an object to be measured with a predetermined pressure and the stiffness of the object to be measured in the squeal frequency band ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9618434","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
