A muffler is a key component of a car's exhaust system, designed to reduce noise levels and emissions. The vibration of a muffler can have a significant impact on its performance and life. In order to understand the performance and behavior of the muffler, it is necessary to make multi-point vibration measurement. First, it enables engineers to assess the structural integrity and durability of a m...
