Acquiring force data in real time and live is critical to understanding the complex physics involved during the transitions of strides of the horse, every movement of the horse affects the sulky in some fashion, also every movement of the sulky affects the horse. Newton's Third law: When a first body exerts a force on a second body, the second body simultaneously exerts a force on the first body. The force is equal in magnitude and opposite in direction.
Page 3 on this site will describe in detail the locomotion of the horse and what affects the sulky has on the horse while being pulled at speed. An excerpt from the book "The Lame Horse" written by world renowned veterinarian Dr. James R Rooney will be cited.
Pressure gauges were used in the first experiments testing the Force Equalizer, after confirming the concept, digital components replaced the gauges. Using thin filmed pressure transducers with an output of 4-20 ma connected to a Dataq DI-145 data acquisition module, we were able record data on a waveform browser using a Toshiba laptop as a processor.

Welcome. On this website we are going to provide an insight into the future embodiment of the racing sulky, and how it will evolve. We are going to examine the different types of racing sulkies and equipment used in standardbred racing. Our objective is to create a design for a racing sulky which will enhance its performance, while at the same time design ergonomically friendly sulkies for the harness racing drivers, trainers as well as the equine athlete. My opinion is that if a horse is comfortable while racing, the horse will perform better. Our goal is to obtain and analyse data acquired with the "Sulky Force Equalizer and Analyzer" . We will use this data for designing sulkies with superior tracking, superior anti vibration materials and components, as well as superior structural strength. The Sulky Force Equalizer and Analyzer not only acquires data from a sulky, it also can acquire data from the horse. Each step a horse takes can be recorded and displayed on a waveform browser. You can determine what foot hits the ground, how long its in contact with the ground, the magnitude of of force, the acceleration and deceleration that is produced and the duration of each individual step. Acquiring and recording data such as this can provide countless benefits from diagnosing lameness issues in the early stages to comparing a horses gait signature to that of a champion racehorse. In the future you might see along with the pedigree of the horse, a waveform display of the horses gait signature. The analyzer is a comparable piece of equipment to the "Black Box" used on aircraft to record flight data such as g-force, roll, pitch and yaw motions. We are also going scrutinize some beliefs or opinions concerning the uplift theory. Hopefully with this effort we will be able to ascertain what is actually fact or fiction. Questionable data, calculations and observations obtained in the early 70's seems to be a little confusing as well as misleading.
Also during our experiments we are going to explore the affects of driver and sulky weight as well as wind resistance and track surface friction.
The above photo is the Sulky Force Equalizer installed on a Tel Star Eliminator sulky. This configuration would be used for racing.

The photo above taken making a 180 degree turn, the Sulky Force Equalizer allows for an abundance of mobility. Note the hitch on the right fully extended, the hitch on the left fully retracted.
The images below is the newly designed Sulky Force Equalizer being checked for sizing and compatibility on a Tel Star sulky. Powder coating or nickel plating will be the next step prior to installation on the new sulky. Final destination of the hitch will be somewhere in the Pocono mountains.
