Characterising Modal Behaviour of a Cantilever Beam at Different Heating Rates for Isothermal Conditions

The effect of temperature on structural response is a concern in engineering applications. literature has highlighted that applied loads change the system vibration behaviour. However, there limited information available about impacting dynamic response. This paper investigated heating rates effects modal parameters for both with crack and without conditions cantilever beam. A beam subjected to three was considered: 2, 5, 8 °C/min. first one assumed as slow rate while others were moderate high, respectively. controlled achieved by using proportional-integral-derivative (PID) controller. results showed at different little impact parameters. While this minimal lower temperatures more evident higher temperatures. ramped °C/min compared numerical analytical only all isothermal conditions. It observed natural frequency its amplitude decrease increase depths. Therefore, it concluded can make slight dynamics any mechanical system.
