1) Suspension Analyzer v2.4 B Released  Based on your feedback, we've been working very hard on several new features for the Suspension Analyzer v2.4 B.  

 

Some of the new features include:

• The program has 2 new steering options to simulate Alfa Romeo and solid axle Jeep suspensions.
• You can now use a panhard bar or a watts link with leaf springs as the Lateral Locator. 
• The program has new inputs in Vehicle Specs for front, rear or all wheel drive (what percent of the power is being delivered through the front drive tires), inboard or outboard brakes, unsprung weight.
• There are new Calculation Utility "Clc" screens calculating King Pins dimensions for solid axle front suspensions, and bump springs (including "stacked springs").
• The program now allows you to specify what the opposite end of the car is doing. This lets you apply "pitch" to the car to see what happens to the calculations. 
• You can now enter specs for bump springs for the front and/or the rear suspension. (This feature is not available for push or pull rod type suspensions.)  
• The program now calculates and displays new outputs, like Bump Spring Force and Dynamic (after dive and roll are applied) Roll Stiffness, Roll Couple, Front and Rear Lateral Load Transfer, and Natural Frequencies. This is very handy to watch what happens once the Bump Springs are encountered with suspension movement. 
• There are new inputs for Ride Height. You can then watch Ride Height change when you apply Bump and Roll and the new Pitch input to the suspension. When you do a top view of the suspension, the location where the Ride Height measurements are made are drawn as small boxes. These measurement locations are located in the Vehicle Specs screen, as they always have been. 
• You can now include a picture file with the suspension which will be drawn on the main screen if there is room, and included in printouts of reports or graphs as you direct. 
• The program now reads some types of Bill Mitchell’s WinGeo (.gem) files, like double a arm and McPhearson strut.
• The program now remembers some inputs you have entered in the "Clc" calculation utility screens, like for spring rate, roll bar rate, and the new Unsprung Weight, and more. These are saved with the file, so in the future you will know where, say, the roll bar rate came from.

2) Shock Dyno - Big Force Testing We often get questions like "Can a 1.5 HP motor handle the 'high tie down' shocks now used in many circle track classes?"   We recently ran one of these JRI shocks with close to its max 'tie down' setting with the results shown below.  You will see that it is handling over 1850 lbs at about 6 in/sec.  This is a fully computerized, very rugged, "scotch yoke" shock dyno starting at the low price of just $4499.
