Development of Data Logger for Motorcycles 2015-32-0828

The data loggers that are used on motorcycles are intended to measure the running data during races and when driving on closed courses [1]. These data loggers are small in size, lightweight, and optimized for mounting on motorcycles so that they do not affect the vehicle dynamics. Consequently, almost all of these data loggers are not equipped with the amplifiers and filters necessary for taking measurements from strain sensors. Most of the data loggers that have amplifiers and filters built into them are large in size and cannot be used on a motorcycle while it is being driven because of their poor durability, poor water resistance, and poor dust resistance. However, it is necessary to carry out strain and acceleration measurements when developing a new motorcycle body so that the body strength and motion characteristics can be understood [2][3]. Furthermore, the ability to increase the number of measurement channels and acquire position information is also being demanded to improve the efficiency of development and deepen our understanding of the phenomena that occur during driving.

Consequently, a new data logger was developed for use during the development of new motorcycle bodies. In the data logger that was developed, both amplifiers and filters are built in and it is able to measure the information coming from each of the various sensors. The number of channels was also increased by synchronizing multiple data loggers. In addition, the durability, water resistance, and dust resistance of the data logger were all improved by injecting resin inside the data logger case. As a result, the most suitable data logger for use during the development of new motorcycle bodies was developed.
