Brake Hysteresis Test using CompactDAQ and LabVIEW

Brake Hystersis Test

Overview

Brake Hysteresis Test using CompactDAQ and LabVIEW. An automotive lab needed a program to perform brake testing. The system had to acquire data from multiple load cells, control solenoids, and activate load cell shunts. The software had to plot force and position on an XY graph. The customer also needed a real time numeric display of the measurements and save the data to a predefined excel template.

In Vehicle Brake Controller Data Acquisition

data_acquisition

Overview

A company manufacturing brake controllers for towing trailers needed an in-vehicle test system that monitored various quantities (i.e. brake temperature, vehicle speed, brake distance, etc.). The company needed the system to be flexible enough to add or remove data channels as needed. They also needed a triggering function (i.e. when a data channel reached a certain level the data acquisition would begin). Logging the data to an excel file was required. A read back function was needed to display the data for analysis purposes.

Wireless Data Acquisition System

WDAS

Overview

An automotive company needed to monitor the temperature and pressure of a fluid inside a fan clutch. They needed a custom circuit board to collect 4 channels of temperature data and 4 channels of pressure data. This data then needed to be sent wirelessly to a PC to be logged for later review. The circuit board and housing needed to be balanced along the x and y axis due to the fact it was mounted directly to the fan clutch. Any unbalance would cause the clutch to vibrate, yielding erroneous data.

Automotive Side Mirror Functional Test

Overview

An automotive supplier that manufactures side mirrors needed to upgrade their automated mirror testing station. The previous software required the operators to analyze the data from each run using a cumbersome software tool and transfer the results to a hand written report. The user interface wasn't intuitive, and required the operator to do a lot of manual set up. The operator also had to do a manual analysis to determine if the mirror passed or failed the test. Finally the data from each run could not be saved for later analysis.

Optical Probe Test

Overview

A research and development department needed custom automated measurement software to control and monitor an experiment. They needed the software to communicate with a Infrared Spectrometer, Optical Reflectance Probe, a Temperature Controller, and a Pressure Controller. The software also needed to control a 3 axis motor drive. The experiment also had to run in an automatic and manual mode, and save the acquired data for analysis.
